Echmatemys cibollensis
Taxonomy
Emys cibollensis was named by Cope (1877). Its type specimen is USNM 2578 (holotype), a partial shell (shell fragments), and it is a 3D body fossil. Its type locality is Gallinas River region, which is in a Wasatchian terrestrial horizon in New Mexico.
It was synonymized subjectively with Echmatemys lativertebralis by Lichtig and Lucas (2015); it was recombined as Echmatemys cibollensis by Hay (1906), Hay (1930), Zonneveld et al. (2000) and Vlachos (2018).

---|---|---|
E. Vlachos 2018 | “Echmatemys” cibollensis can be diagnosed as a member of Pan-Testudinoidea based on the extensive covering of the plastral scutes viscerally and is tentatively associated with Echmatemys based on the morphology of the epiplastra. “Echmatemys” cibollensis differs from other Echmatemys by the restriction of the short and wide gulars to the epiplastra and medial covering of the epiplastra by the humeral scutes. |
