Anatomy and Paleontology

I am a comparative anatomist by training, and my main research areas are vertebrate paleontology and human anatomy. Along with my coauthor and colleague Mike Taylor, I blog about paleontology and anatomy at Sauropod Vertebra Picture of the Week, https://svpow.com/.

In my spare time I enjoy stargazing, and I write the monthly Binocular Highlights column and the occasional feature article for Sky & Telescope magazine.

    Paleontology and Comparative Anatomy

    As a paleontologist I have mostly worked on long-necked sauropod dinosaurs and the evolution of air-filled bones in dinosaurs and birds. I’m also interested in the evolution of heads and necks in vertebrates, and in the nervous systems of very large animals. I’ve been fortunate to coauthor three papers naming new dinosaurs: the sauropods Sauroposeidon (2000) and Brontomerus (2011), and the early horned dinosaur Aquilops (2014). In 2016 my book The Sauropod Dinosaurs: Life in the Age of Giants, with artist and lead author Mark Hallett, was published by Johns Hopkins University Press. I currently do fieldwork in the Late Jurassic Morrison Formation in Utah and the Oklahoma Panhandle.

    Human Anatomy

    In the arena of human anatomy, I’m particularly interested in variation in the nerves and muscles of the lower extremity, and in structures derived from the embryonic pharyngeal arches. I regularly mentor WesternU students in anatomy-based research projects.
