Denazinemys was a genus of baenodd 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]
Distinguishing characteristics
Previously, Scabremys ornata was assigned to Denazinemys as D. ornata. Below are the features distinguishing the two genera:[1]
- a carapace sub-triangular with widest dimension posteriorly;
- prepleurals present and contacting the first vertebral medially;
- first vertebral irregular hexagonal shape with greatest width posteriorly, contacting anterior second vertebral;
- extracervicals lateral to primary cervical, gular sub-divided;
- and carapace nodes irregular and not forming distinct anteroposteriorly-directed ridges.
