A review of the fossil record of nonbaenid turtles of the clade Paracryptodira

Joyce, Walter G. ; Anquetin, Jérémy

In: Bulletin of the Peabody Museum of Natural History, 2019, vol. 60, no. 2, p. 129–155

The fossil record of nonbaenid paracryptodires ranges from the Late Jurassic (Kimmeridgian) to the Paleocene of North America and Europe only. Earlier remains may be present as early as the Middle Jurassic (Bathonian). Only a single dispersal event is documented between the two continents after their breakup during the Cretaceous in the form of the appearance of the Compsemys lineage in the ...

A new testudinoid turtle from the middle to late Eocene of Vietnam

Garbin, Rafaella C. ; Böhme, Madelaine ; Joyce, Walter G.

In: PeerJ, 2019, vol. 7, p. e6280

Testudinoidea is a major clade of turtles that has colonized different ecological environments across the globe throughout the Tertiary. Aquatic testudinoids have a particularly rich fossil record in the Tertiary of the northern hemisphere, but little is known about the evolutionary history of the group, as the phylogenetic relationships of most fossils have not been established with...

A Review of the fossil record of turtles of the clade Pan-Kinosternoidea

Joyce, Walter G. ; Bourque, Jason R.

In: Bulletin of the Peabody Museum of Natural History, 2016, vol. 57, no. 1, p. 57–95

Turtles of the total clade Pan-Kinosternoidea have a relatively poor fossil record that extends back to the Late Cretaceous (Campanian). The clade is found only in North America during its early history, but dispersed to Central America no later than the Miocene and to South America no later than the Pleistocene. Ancestral pan-kinosternoids were likely aquatic, bottom-walking omnivores or...

A review of the fossil record of turtles of the clade Pan-Carettochelys

Joyce, Walter G.

In: Bulletin of the Peabody Museum of Natural History, 2014, vol. 55, no. 1, p. 3–33

Turtles of the total clade Pan-Carettochelys have a relatively poor fossil record that extends from the Early Cretaceous. The clade is only found in Asia during the Cretaceous, but spreads to Europe and North America during the Eocene. Neogene finds are restricted to Europe, Africa and Australia, whereas the only surviving species, Carettochelys insculpta, lives in New Guinea and the Northern...
