Episode 61: WitmerLab
Dr. Larry Witmer’s lab at Ohio University studies the anatomy of modern animals to make interpretations regarding the functional morphology of extinct vertebrates. WitmerLab incorporates anatomical studies with cutting-edge technology, allowing for the reconstructions of soft-tissue structures no longer present in fossils (including respiratory apparatuses, brains, and inner ears). These reconstructions allow Dr. Witmer and his students to study the original physiology, biomechanics, and evolutionary adaptations of creatures long extinct.

“This model accompanies an article published in the open-access journal PeerJ on 8 December 2015 (https://peerj.com/articles/1475/), describing the skull of the basal ankylosaur Kunbarrasaurus ieversi (formerly Minmi sp.) from the Lower Cretaceous Allaru Mudstone of Queensland, Australia, with an analysis of its brain endocast structure (blue), cranial nerves (yellow), inner ear (peach), nasal passage (green), olfactory chamber (pink), and nasal loop (purple). The article authors are Lucy G. Leahey, Ralph E. Molnar, Kenneth Carpenter, Lawrence M. Witmer, and Steven W. Salisbury. 3D modeling of the skull and internal structures was done by Ryan Ridgely. The background image shows the near complete holotype skeleton (QM F18101); photo © O’Toole & Leahey. See https://skfb.ly/IO9w for an annotated Sketchfab of the skull.”
