description Lawrence Witmer Overview

Lawrence Witmer is an American paleontologist known for applying advanced CT scanning to the study of extinct vertebrates. His research uses internal fossil evidence to reconstruct soft tissues, brains, and sensory systems that are not normally preserved as visible bones. The work is especially relevant to studies of dinosaur anatomy and to researchers and students examining how anatomy and sensory biology can be investigated through digital paleontological reconstruction.

help Lawrence Witmer FAQ

What does Lawrence Witmer use CT scanning to study?

Witmer uses CT scans and 3D visualization to examine cavities and structures hidden inside fossil bones. This can reveal evidence about brains, inner ears, nasal passages, blood vessels, muscles, and other soft tissues.

Where does Lawrence Witmer teach and conduct research?

Witmer is a professor at Ohio University, where he is also the Chang Ying-Chien Professor of Paleontology. His WitmerLab combines paleontology, anatomy, CT imaging, and computer modeling.

Does Lawrence Witmer study animals besides dinosaurs?

Yes. His work covers extinct vertebrates including pterosaurs as well as dinosaurs such as Tyrannosaurus rex. He also compares fossils with living birds and crocodilians to make anatomical reconstructions.

What is the extant phylogenetic bracket used by Witmer?

It is a method that compares living relatives of an extinct animal to infer soft tissues that fossil bones do not preserve directly. In dinosaur research, birds and crocodilians provide the living comparison points for reconstructions of features such as the brain and breathing system.
