Dr. Lawrence M. Witmer is an American paleontologist and paleobiologist. He is a Professor of Anatomy and a Chang Ying-Chien Professor of Paleontology at the Department of Biomedical Sciences at the Heritage College of Osteopathic Medicine in Ohio University. Witmer is considered to be one of the world's foremost experts on soft-tissue anatomy of the skull in extinct animals such as dinosaurs and pterosaurs.[citation needed] One of Witmer's largest contributions to vertebrate paleontology was the creation of the Extant Phylogenetic Bracket approach to ancestral character state reconstruction.[1] This methodology incorporates extensive comparative anatomy using physical and digital dissections of extant animals.[2]
