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 found in Denazinemys distinguishing the two genera:[1]
- a carapace that is sub-triangular with widest dimension posteriorly;
- prepleurals present and touching the first vertebrae medially;
- the first vertebrae an irregular hexagonal shape with the greatest width posteriorly, contacting anterior second vertebrae;
- extracervicals lateral to the primary cervicals, the cervicals being sub-divided;
- and carapace nodes irregular and not forming distinct ridges.
Classifiation
Denazinemys is a baenodd, 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]
