Tanytrachelos is an extinct genus of tanystropheid archosauromorph reptile from the Late Triassic of the eastern United States.[1] It contains a single species, Tanytrachelos ahynis, which is known from several hundred fossil specimens preserved in the Solite Quarry in Cascade, Virginia. Abundant fossils of Tanytrachelos are found in a series of lakebed sediments that were deposited over the course of about 350 thousand years in a lake which existed approximately 230 million years ago. Some fossils are very well-preserved and include the remains of soft tissues.[2][3] Tanytrachelos is the most likely trackmaker of the ichnogenus Gwyneddichnium.[4]

A "type A" Tanytrachelos, believed to be a female.

Tanytrachelos remains have also been found in the Chinle Formation of Arizona[5] and the Lockatong Formation of New Jersey.[6]
