“Breath-Taking” Brachiopods

July 13, 2017

Written by Chilea Dickson, Paleontology Summer Intern

As a biology major at Shaw University, I was very eager to participate in the NSF funded Paleontology internship at the North Carolina Museum of Natural Sciences. Coinciding with my study of living organisms, I was able to step beyond the “grave” to see the history of the living through paleontology, which is the study of fossils. Paleontology has always been a fascination of mine, however, I have not had any exposure to it. But this was my opportunity! The first day of my internship, I was introduced to brachiopods (which I had never even heard of before!)

Looks like a clam right?! Wrong! It’s a beautiful brachiopod!

What is a brachiopod?

Look at the very intricate design of this fascinating creature!

Brachiopods are the only members of the phylum Brachiopoda and are a clade of protostomes, meaning the mouth develops before the anus in the embryonic state. Brachiopods look similar to clams, but their anatomy is quite different. Brachiopods have hard shells, with two unequally sized valves. The larger valve is the pedicle valve and the smaller is the brachial valve.

Photo of a brachiopod showing the two unequally-sized valves.

Notice how the pedicle valve overlaps the brachial valve.

Their shells are hinged at the back end, while the front area can be opened for feeding, or it can remain closed, for protection. Brachiopods have a fleshy stalk at their back end called a “pedicle” which is used to attach to a substrate.

An extant brachiopod. The lovely structure that looks similar to a tail is actually the pedicle. This specimen is part of the NCSM’s Non-Molluscan Invertebrate Collection.

These marine organisms were abundant in the Paleozoic era (about 251-542 million years ago). Brachiopods, though less common, are still around today. But think about how long these animals have been around and what they might have lived through. Wow! Brachiopods bring a whole new meaning to “survival of the fittest!”

Brachiopods were around before dinosaurs!!!

Cabinets and Cameras

July 11, 2017

Written by Mark Reyes, Paleontology Summer Intern

As an Environmental Science major at North Carolina Central University, what better way to start my future professional career than by getting a head start as an intern at the North Carolina Museum of Natural Sciences. Over the course of two months, I’ve had the opportunity to work alongside some of the best paleontologists in the state. Every week, for three days, two other interns and I would move drawers and boxes of various fossil bones, shells, rocks, and even dinosaur poop from old cabinets and into new cabinets. Sometimes cabinets also had to be moved. Usually this process involved a lot of strenuous muscle activity similar to a day at the gym doing crossfit.

Moving drawers and specimens often included going up on ladders to reach top cabinets that either needed to be filled or emptied. Chilea Dixon (left), Elizabeth Altier (middle), and Jacob Van Veldhuizen, Paleontology Collections Technician (top right).

My internship wasn’t just about reboxing, or moving never-ending drawers of unorganized fish vertebrae (enough for pescatarians to go vegan), we also had the opportunity of photographing fossils from collections and turning them into 3D models for the museum’s website at the Natural Research Center (NRC), just a bridge away from the “old’ part of the museum (NEC).

Drawer after drawer of Tetradontidae Osteichthyes (fish) vertebrae had to be moved and/or re-boxed. Most of them were unorganized or had multiple specimen cards with their assigned fossil in a single box. These fossils had to be re-boxed individually which would take up an enormous amount of time.

One of the tasks assigned to us paleontology interns was to turn fossil photos into a virtual 3D models. Taking pictures involved making sure to get just the right amount of light and that the image is focused on the fossil. Sometimes this wasn’t easy, especially for small tooth specimens. Teeth are hard to capture because they are small and because they reflect a lot of light. Because of this we had to change the backdrop to a baby blue color and we had to cover the tooth with baby powder. This proved much more successful than using a black backdrop.  Taking photos of these fossils required what looks like a miniature makeshift photo studio placed in front of a camera where the fossil is turned multiple times to get all angles. After making sure each angle of the specimen has been captured, the next step was to transfer photos to the computer where the process of editing and 3D modeling takes place.

Resident graduate student, Khai Button at the Paleontology Lab at the Natural Research Center (NRC) working on a 3D model of a plant fossil (Annularia) using PhotoScan Pro.

Using Photoscan Pro (the computer programs that creates the models) was not easy, but eventually through much trial and error (enough to drive my supervisor nuts!) most of the 3D models turned out well. The process involved masking and editing pictures from “chunks”, (different angles of the specimen) and applying markers to create a polished virtual version of the fossil. 2D images will then be downloaded onto the museum’s website. Pictures and information of specific fossils can be accessed here by using key information such as a specimen number and/or other information such as genus.

In June we had a new shipment of cabinets come in. We used pallet jacks to transfer full and half cabinets from one floor to another. In the weeks following, we moved several cabinets, drawers, and fossil specimens around while splitting other responsibilities such as photo taking and re-boxing each week.Somewhere along the way we ran out of small boxes, and it didn’t make sense to transfer a small, individual fossils into a large box that would take up too much space in a drawer. After these small boxes ran out, we had to eventually halt re-boxing. However, this did not prevent our supervisors from finding things to keep us occupied.

By marking the boxes with a pH indicator box we can determine whether these boxes are acid-free. A purple mark indicates an archival box while a brown mark indicates a non-archival box.

As I am writing this blog, my fellow interns and me are now filling our time by attending staff meetings and museum-related tours. The museum hosted a series of lecture meetings throughout the summer. The primary focus of these weekly meetings was to find better ways to communicate science to the general public. Open to interns and the staff, such meetings included how to talk to the media and how to communicate science to elected officials and policy makers. The museum also hosted a geology tour around downtown Raleigh and a dinosaur tour over at the NRC.

Although museum-related activities were fun and oftentimes very insightful, our supervisors were not necessarily paying us (well, some of us) for this time outside of collections and the paleontology lab. So new tasks such as identifying specimens and cleaning shells of Byne’s disease have been added to our list of duties. Taking pictures however, is still one our main priorities.

Reflecting back on this whole internship experience, I can’t help but be thankful for the opportunity that was given to me. It was quite nostalgic to be surrounded by fossil specimens of every kind and to be around paleontologists and specialists of other scientific backgrounds.

As an environmental science major at NCCU, and an aspiring ornithologist, I deeply appreciate the work of scientists, more so than before I started my internship. I learned through cabinets and cameras, that the scientists I’ve come across here at the museum were once annoying students and interns too.

I am a senior at NCCU getting my degree in Environmental GeoScience. I plan to stretch my academic career to become an ornithologist someday. Thank you to the Natural Science Museum and the amazing crew at the Paleontology department. I still often wonder why you guys hired a short Filipino kid with little muscle strength to move heavy cabinets around. It was still worth it. 🙂

Things to do when your kid likes rocks.

July 1, 2017

You’ve just entered that stage of parenthood where your offspring is developing strong interests in scientific topics. And that topic is rocks and minerals. What to do? There aren’t any shots for it. I know.

It’s a good thing to encourage. Geology is the perfect gateway into the physical sciences. College students take geology to avoid biology, chemistry, and physics, only to discover that geology is all of those and more. The science of geology is very interdisciplinary, so it has a lot of polymath types who have a wide range of interests. If your child is good at more than one thing, the Earth Sciences are probably a good match. Even better, the geosciences require good three-dimensional visualization skills. So does Art. If you have a young artist with a liking for the sciences, Geology is right where they would fit in best.

There are lots of family outings in North Carolina for the whole family. We have a terrific State Parks system that covers the whole state. Best of all, there are books on the geology of the parks to help. Kevin Stewart and Mary-Russell Roberson put together Exploring the Geology of the Carolinas: A Field Guide to Favorite Places from Chimney Rock to Charleston. Kevin Stewart, and the science is well explained. Free guidebooks  are available to download as pdf files from the Carolina Geological Society. There’s a good chance that an area near you is covered. CGS meets once a year for a field trip and banquet, and the membership is open to anyone.

If you would rather go collecting minerals, there are a lot of clubs in the state just for that purpose. If you are local to Raleigh and Wake County, there is the Tarheel Gem and Mineral Club. North Carolina’s other big cities have gem and mineral clubs as well, Winston-Salem and Forsythe County, Greensboro, and Charlotte. Kids will need to have an adult with them out on a collecting trip. In addition to meetings with speakers and trips for collecting, the gem and mineral clubs usually have a yearly show.

Gem and minerals shows are always an event. Most have minerals specimens and fossils for sale, as well as beads and jewelry. The next big one is in Franklin, NC at the end of this month (July, 2017). The following week is the Spruce Pine, NC show. The Tar Heel Gem and Mineral Club holds a big show the first weekend in April. If you keep an eye on the schedule, there are other shows at the North Carolina State Fairgrounds a couple of times a year.

And did I forget to mention museums? The Schiele Museum in Gastonia is opening a new and updated Earth Science exhibit hall . You can watch for updates at their main page (click here).  On the Blue Ridge Parkway is the Museum of North Carolina Minerals near Spruce Pine, always a fun stop. The local Chamber of Commerce has information there to help you find the commercial gem panning operations, too. The Colburn Earth Science Museum in Asheville has a new location, new exhibits, and a new name, the Asheville Museum of Science. Their wonderful mineral exhibits are still there, in the Colburn Hall of Minerals.

And, of course, the oldest of these is the North Carolina Museum of Natural Sciences. Come see us first.

Bogoslof Volcano

June 19, 2017

You may (or may not) have noticed that I have been absent from the R&C blogs for quite some time. What can I say? I had cancer surgery in December of 2014, which caused it to snow and delay my escape departure from the hospital. Back surgery for a major broken disc took place barely a year later, which also caused it to snow. I tore a rotator cuff the day of back surgery. That was repaired about 8 weeks later, well into the springtime to prevent further snowing. Then a second rotator cuff surgery about three months later, when the original repair popped loose. Sometime about August of 2016, I realized that I had been taking pain killers for more of 2016 than I had been without them. Any blog I might have written would have been pretty random.

One symptom of rotator cuff tears is that it keeps you awake. Pain is bigger at night. That’s when I started reading Twitter. Late at night, 140 characters are just about right for reading material. If you’re full of pain killers and muscle relaxers. And if you can only use your left hand because your good hand is in a sling.

Much of my Twitter feed is geologist friends, and scientific societies like the American Geophysical Union and the Geological Society of America . The ones I follow most closely are from the United States Geological Survey- the volcano observatories and the seismic alert network. Yes, kids, that’s entertainment to me, perhaps more of an anti-social media than social media. Other people follow actors and actresses, or comedians, or political figures, but I’d rather know what’s shaking and blowing up.

My Twitter feed has been full of the eruption of Bogoslof volcano, a 6,000 foot tall edifice, of which only 200-300 ft. peeks out above sea level. It was named by Russians when it surfaced during an eruption in 1796. There’s lots of Russian names scattered through the Aleutian Islands because they were first explored by Vitus Bering, a Danish cartographer serving Tsar Peter I. The Bering Sea and Bering Straits were his greatest hits.

Geologists are interested because the Aleutians are an island arc, explosive volcanoes that form over a subduction zone. During tectonic collisions, island arcs are jammed onto the edges of continents. It’s one way the continents get bigger.

NC map2

Volcanic island arc rocks of the Carolina Terrane are shown in blue-green. Pink shows granite about 300 million years old, and dark brown shows Triassic Basins. Dark blue is the edge of North America, and gray is terranes that may or may not be North America.

North Carolina’s own Carolina Terrane is one example. It collided with North America about 450 million years ago. It’s of interest to geologists and everyone else as the real estate where most of North Carolina’s gold is found.

At iris.edu, you can use the 3D seismic viewer  to look at the downgoing oceanic slab north of the trench. To find Bogoslof, first find the Okmok Caldera (classic volcanic mountain with circlular hole on top) on northern Umnak Island. Bogoslof is north of that. On the next island east, Unalaska, you can follow the outlet of the Makushin Bay west to Bogoslof. It works best if you pick a high number of earthquakes, press “Apply”, then push the “3D view” button. With the mouse, you can “grab” the S (for South) and flip it up and rotate it.

Aleutian earthquakes

Looking below the surface at the earthquakes shown above. Light blue line is, again, the deep trench. Away from the trench, earthquakes accompany the oceanic crust as it dives back into the mantle. The islands in white are volcanoes above this subduction zone. Graphic created with the 3D Seismic Viewer, Iris.edu.

Earthquakes mark the top of the slab. As it descends, it releases water that causes melting, and the melt migrates to the surface as magma. The slab in this area is very steep, so the line of volcanic islands is fairly narrow.  Volcanoes are basically a pipeline to return water and carbon dioxide to the surface.

The excitement started on 16 December of 2016, although when they looked back, unrest started earlier in the month. Since then, there have been more than 40 explosive eruptions.  One big burp of sulfur dioxide gas was followed by satellite from Alaska to Nebraska.

Bogoslof volcano is fun because it’s so far away from anything that it’s only monitored remotely. It has to be monitored, because it can blow ash high enough that the cloud can disrupt airline traffic. Ash clogs the jet engines, then melts in place so that the engine is dead. Volcanic gasses tend to be very acidic, which isn’t exactly the cure for engine trouble. Finally, all the windshields get sandblasted. So the Alaska Volcano Observatory (AVO) pulls out all the stops. Seismic, satellite, infrared, infrasound, lightning detection, and a few pictures taken from Alaska Airlines flights or Coast Guard boats. Much of this is available online, so you can track as the island is blown up and rebuilt on a weekly or daily basis.

Seismic data shows what happens below the ground, and infrasound what happens above. Lightning is the result of ash particles rubbing together.

It easy to remember that the Year Without Summer, 1816, was the result of the eruption of island arc volcano Mount Tambora. Volcanic aerosols lowered global temperatures enough to cause worldwide famine and crop failures. Farmers in North Carolina suffered poor crops, but farther north and at higher elevations, there were no crops. I suppose I watch volcanic eruptions for the same reason people watch weather forecasts.

Volcanic eruptions are good for the spirit, too. They remind me that the Earth is alive, living on a time scale much different from the regimented days and weeks of human time. The Earth’s clock creeps and jerks erratically, but there is always lots of time. Plenty of time. That’s a good thing to remember. There’s always something going on, especially when you’re stuck in bed, flat on your back.

 

Paleontology Collections Move: Invertebrates Part 2: Re-boxing

March 7, 2017

In between shipments of new cabinets, we finally have some time to start re-boxing, and relabeling our specimens. You might be thinking, why bother? Aren’t your new cabinets all archival? They are, but a lot of the boxes the specimens are in and some of the labels are not. In the Invertebrate Paleontology Collections this can lead to Bynesian decay or “Byne’s disease.” Byne’s disease occurs when acidic vapors react with calcium carbonate. As some, most or all of you know, a lot of invertebrate shells, tests, or other hard parts are composed of calcium carbonate. Over time, non-archival boxes or non-archival labels reacting with water vapor (we do open our cabinets and humidity is a problem in NC) can give off acidic vapors, which in turn can cause decay and deterioration of our invertebrate specimens. So we are re-boxing and relabeling with archival materials. But there is more to it than simply swapping boxes.

Crayfish fossils in their old cabinet and boxes. Note the labels are all akimbo.

Jacob and I have been using our fossil crayfish collection as a means to work out a re-housing protocol that we can then use for all the specimens in the Paleontology collections. Jacob will be presenting a poster on this in April at the Association for Material and Methods in Paleontology (AMMP) meeting.  As illustrated below, steps include checking to see if specimens need repair, treatment for Byne’s or pyrite disease, or additional preparation. Our crayfish specimens need preparation which one of our volunteers, John Adams, is doing a spectacular job of.

Photo of John's hands as he prepares a crayfish fossil using an airscribe.

John doing the delicate task of preparing one of our crayfish fossils.

Prep work takes time, so in the interim we’re checking to see if the current box and labels are archival. If not, then it’s time for re-boxing and relabeling.

Photo of a man sitting at a table full of fossil crayfish specimen and tubs of pre-cut foam.

Jacob starts the task of swapping non-archival boxes for archival boxes and adding foam to separate matrix vials from specimens.

We’re also adding archival foam to the box to either cushion the specimens or to separate them from matrix samples, or from other specimens in the same box. Because these crayfish fossils are being used as a part of a research project, we are making an effort to keep the matrix that comes off during preparation. But we don’t want the matrix vial rolling into, and potentially damaging, the crayfish.

Photo of three crayfish fossils in archival boxes with foam separating them from their matrix vials.

Frequently, we don’t write specimen numbers on specimens until after preparation. There are many reasons for this including, the likelihood that the number will be etched off. Mind you this can lead to chaos if the people preparing the specimens don’t keep labels with specimens. With the crayfish specimens we’re numbering the specimens after preparation and are trying not to write directly on the specimen. So we’re painting a small stripe on the surrounding matrix on which we can then write the specimen number.

Photo of a woman's hands painting small white stripes on the back of crayfish fossil. On the table are two specimens that have already been painted.

Trish paints small white stripes on the back of fossils specimens. Once the paint is dry, she’ll write the specimen number on the painted stripe.

As you might imagine, none of this is a particularly quick process, but I think you’ll agree the results are worth it.

A Few Words About Words

February 24, 2017

Scientists, you’ve got to love us. We use a whole lot of big words to describe everything, even ourselves. For example, I’m a paleontologist (someone who studies fossils), a geologist (someone who studies the Earth), and a taxonomist (someone who spends way too much time classifying organisms according to their presumed natural relationships). If you’re a taxonomist like me, it means whenever you work on a new group of organisms, you need to learn a whole new vocabulary. It’s kind of like learning a foreign language. Ever wonder where these words come from and why they are necessary? Well…I’ll tell you.

I’m currently working on a group of organisms known as entocytherid ostracods (seed shrimp… though technically they aren’t shrimp… don’t get me started). Entocytherid ostracods are ectosymbionts of other crustaceans… Just stop with the jargon already and get to the point!

Photo of a gravid female of Dactylocythere daphnioides, an entocytherid ostracod from North Carolina displaying its ruffled skirt. The balck arrow points to the ruffled skirt, the red arrow points to the egg mass.

Gravid female of Dactylocythere daphnioides, an entocytherid ostracod, which was removed from a crayfish from North Carolina, displaying its ruffled skirt.

One of the new words I’ve recently learned is “amiculum”, which comes from Latin, meaning a mantle or cloak. So why not just use mantle or cloak? Well, there’s a story behind that. Back in the day, 1955 to be exact, Horton Hobbs Jr. described a particular piece of anatomy seen in adult female entocytherid ostracods as the “ruffled skirt.” Though other authors, Crawford (1959), Hobbs and Walton (1960), followed suit, a problem arose in 1961, when Hobbs and Walton discovered an entocytherid “species” with a decidedly “unruffled skirt!” These authors explain it this way …”it seems inappropriate to refer to it as an unruffled, ruffled skirt. Although neither the minute structure, nor its function is understood, to aid in the preparation of future descriptions we propose that it be designated the amiculum (L.-a mantle).”

Photo of a gravid female of Donnaldsoncythere donnaldsonensis from New York displaying a decidedly unruffled skirt. The red arrow in the center of the image points to the egg mass, the black arrow to the left point to the "unruffled skirt."

Gravid female of Donnaldsoncythere donnaldsonensis removed from a crayfish from New York displaying a decidedly “unruffled skirt”.

Thus the term amiculum is now part of the entocytherid vernacular, which is probably a good thing because there are several genera of entocytherid ostracods whose adult females have neither an unruffled ruffled skirt, nor a ruffled skirt. In fact some wander around with no skirts at all. Oh the humanity!

Photo of a gravid female of Entocythere reddelli from North Carolina showing its amiculum, which for my mind is sort of a combination of ruffled and unruffled skirt. The red arrow in the center of the image points to the egg mass. The black arrow to the left points to the amiculum.

Gravid female of Entocythere reddelli removed from a crayfish from North Carolina showing its amiculum, which for my mind is sort of a combination of ruffled and unruffled skirt.

Though I admit I find this all very entertaining, I find it even more fascinating that to this day, over a half century later, we still don’t know what the purpose of this structure is. The ammiculum is only seen in adult, usually gravid (full of eggs), females. Not all entocytherid genera have this structure. Though it sits in the same portion of the carapace (shell) as the copulatory complex of the males, it is highly unlikely the amiculum is the female equivalent, because mating/impregnation seems to occur before this structure is developed.

Photo of a gravid female of Uncinocythere occidentalis from Oregon. This specimen has lots of egg masses, but isn't wearing a skirt (amiculum). The red arrow in the center points to the egg masses. The black arrow to the right points to the empty space where the amiculum would be if it had one.

Gravid female of Uncinocythere occidentalis removed from a crayfish from Oregon. This specimen has lots of egg masses, but isn’t wearing a skirt (amiculum).

I have plenty of unsupported theories on the subject, but all are pure speculation. Ask me if you’re interested. But I can say entocytherids are weird, and gravid female entocytherids are particularly peculiar. There is one genus, Entocythere, where adult females not only develop an amiculum, they also grow what I like to call an extra “happy hand” on their antennae. What’s the point in that?

Moving Right Along: Invertebrate Paleontology Collections Move Part 1

Bivalves! You want ’em, we got ’em! One box of the many thousands of Invertebrate Paleontology specimens we are moving into new cabinetry.

The NCSM Invertebrate Paleontology Collections contains approximately 58,000 specimens, all of which are moving thanks to a National Science Foundation Collections in Support of Biological Research Grant to the NCSM Paleontology Unit to replace deteriorating cabinetry with archival cabinets.

To do this, we have to move specimens out of old cabinetry, place them into holding cabinets, remove the old cabinets, install new cabinets, then move the specimens into them. Seems simple enough…kind of.

Photo of a woman in the foreground with her hand on a box containing invertebrate specimens, while the man in the background places specimens into a drawer.

Madison and Jacob transfer specimens of Anomia from a cart into holding cabinets.

Nothing is ever that simple. When we removed the row of old cabinetry that was lined up against the wall, we discovered the backs of the old cabinets had been rusting. Time for a bit of elbow grease…and an overnight delay to give the wall time to dry.

Cabinetry install time! Using palette jacks and with the help of NCSM Facilities folks, we got the first row of invertebrate cabinets installed in about a day.

Then it was time to move the specimens again! Bivalves lots of bivalves. This made all of us hungry for clam chowder.

Three carts full of Mercenaria. The genus Mercenaria is still around today. These clams are also known a quahogs, and make a nice chowder or baked stuffed clams.

In under a week we managed to remove an entire row of old cabinets, wash and dry a wall, install new cabinets and fill them with invertebrates. The Invertebrate Paleontology Collection is generally arranged taxonomically, but we do have some cabinets set for site specific collections. In this part of the move we’ve rehoused Protista, Porifera, Bryozoa, Brachiopoda, Cnidaria, and the bivalve part of Mollusca, as well as several site specific collections.

Though this is somewhat back breaking and mind numbing work, it has been nice to see specimens I haven’t seen in years. Please stay tuned for future installments.
