Eotomistoma is a dubious genus of crocodyliform from the Lower Cretaceous of China.
History
Eotomistoma was named by Chung-Chien Young in 1964 based on two pieces of the snout.[1] Young assigned it to the Tomistominae. However, other researchers, such as Eric Buffetaut, were skeptical of Young's interpretation, and in 1981 Denise Sigogneau-Russell re-studied it and determined the specimen was a chimera of a crocodylian and a choristodere.[2] Sigogneau-Russell named the choristodere fossil Ikechosaurus. The remaining snout fragment, still the holotype of Eotomistoma, is now considered to be an indeterminate crocodyliform.[3]
Paleoecology
Eotomistoma is known from the Lower Cretaceous Luohandong Formation. It was a contemporary of the choristodere Ikechosaurus and the crocodyliforms Theriosuchus and Shantungosuchus.[3]
