A Review of the fossil record of turtles of the clade Baenidae

Joyce, Walter G. ; Lyson, Tyler R.

In: Bulletin of the Peabody Museum of Natural History, 2015, vol. 56, no. 2, p. 147–183

The fossil record of the turtle clade Baenidae ranges from the Early Cretaceous (Aptian—Albian) to the Eocene. The group is present throughout North America during the Early Cretaceous, but is restricted to the western portions of the continents in the Late Cretaceous and Paleogene. No credible remains of the clade have been reported outside of North America to date. Baenids were warmadapted...

Fossils provide the principal basis for temporal calibrations, which are critical to the accuracy of divergence dating analyses. Translating fossil data into minimum and maximum bounds for calibrations is the most important, and often least appreciated, step of divergence dating. Properly justified calibrations require the synthesis of phylogenetic, paleontological, and geological evidence and...

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...
