Denazinemys

Denazinemys was a genus of baenid turtle that lived in the Late Cretaceous of New Mexico. The holotype specimen, which D. nodosa was based on, USNM 8345, consists of a partial carapace and plastron. It came from the De-na-zin Member of the Kirtland Formation, and therefore, Denazinemys lived in the Kirtlandian land-vertebrate age. Many specimens other than the holotype have been assigned to Denazinemys.[1]

Previously, Scabremys ornata was assigned to Denazinemys as D. ornata. Below are the features found in Denazinemys distinguishing the two genera:[1]

Classification

Denazinemys is a baenid along with Plesiobaena, Boremys, Scabremys, Baena and Chisternon.[1]

Below is a cladogram made by Sullivan et al. in 2013 showing the relations of Denazinemys: (note: Boremys pulchra is partly a junior synonym of Boremys grandis)[1]
