Plesiochelyidae is a clade of relatively large coastal marine turtles that inhabited the shallow epicontinental seas that covered western Europe during the Late Jurassic. Although the group has been reported from many deposits, the material is rarely identified at the species level. Here, we describe historical plesiochelyid material from the Kimmeridge Clay Formation of England and compare...

The skeletal morphology of the solemydid turtle Naomichelys speciosa from the Early Cretaceous of Texas

Joyce, Walter G. ; Sterli, Juliana ; Chapman, Sandra D.

In: Journal of Paleontology, 2014, vol. 88, no. 6, p. 1257-1287

The fossil record of solemydid turtles is primarily based on isolated fragments collected from Late Jurassic to Late Cretaceous sediments throughout North America and Europe and little is therefore known about the morphology and evolutionary history of the group. We here provide a detailed description of the only known near- complete solemydid skeleton, which was collected from the Lower...
