WitmerLab members are like many paleontologists in having their teaching responsibility in the medical gross anatomy lab. Here Witmer and grad student William Porter work with OU-HCOM med students.

August is vacation time at most universities. For members of our research lab, however, summer is the busy season. We’re completely consumed by teaching a comprehensive medical gross anatomy course at our academic home, the Ohio University Heritage College of Osteopathic Medicine (OU-HCOM). “Wait…what? I thought you were dinosaur guys…paleontologists, not medical people.” I get that all the time. We’re both, and it’s not as crazy as it sounds, nor as unusual as you might think.

Alligators are everywhere. They’re team mascots, Transformer toys, actors in Lubriderm commercials (and CSI: Miami), unwanted golfing partners, and even expensive cowboy boots. What might be a surprise is that they’re also “model animals” for scientists, meaning that there are dozens, if not hundreds, of published technical articles on all things gatorly. They’re also commonly used in K-12 and undergraduate classrooms. WitmerLab has been working on American alligators for years, because crocodilians are one of just two living groups (birds are the other) of that great tribe known as archosaurs that includes dinosaurs and pterosaurs. Now, we’re joining with Casey Holliday’s lab at the University of Missouri to present the 3D Alligator, two parallel, complementary, and growing websites that present alligator anatomy in all its 3D digital glory. In both cases, we’re starting with the skull, although we include a few soft-tissue systems that are active areas of research for us (brain, inner ear, sinuses, etc.). Casey’s team presents an adult skull, and we present a wee gatorling, a “day-0” hatchling that was stillborn on its birthday. Sad perhaps, but this little guy is now immortal, because we’re releasing him to the tubes of the interwebz. We also present some of our 3D alligator work on an adult done “way back” in 2008. Check out the WitmerLab 3D Alligator site and the Holliday Lab 3D Alligator site. (more…)
