Georgalis, Georgios L. ; Villa, Andrea ; Delfino, Massimo

In: Annales de Paléontologie, 2018, vol. 104, no. 2, p. 155–159

The fossil record of amphisbaenians in Europe has recently been augmented through the description of new finds across the continent. It has been suggested that the post- Miocene range of amphisbaenians followed a progressive southward constriction that ultimately lead to their extant disjunct distribution. We herein describe amphisbaenian vertebral material from the Pliocene of northern...

A review of the fossil record of old world turtles of the clade pan-trionychidae

Georgalis, Georgios L. ; Joyce, Walter G.

In: Bulletin of the Peabody Museum of Natural History, 2017, vol. 58, no. 1, p. 115–208

Turtles of the clade Pan-Trionychidae have a rich fossil record in the Old World, ranging from the Early Cretaceous (Hauterivian) to the Holocene. The clade most probably originated in Asia during the Early Cretaceous but spread from there to the Americas and Europe by the Late Cretaceous, to India and Australia by the Eocene, and to Afro-Arabia by the Neogene. The presence of a single...

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

Joyce, Walter G.

In: Bulletin of the Peabody Museum of Natural History, 2016, vol. 57, no. 1, p. 21–56

Turtles of the total clade Pan-Chelydridae have a relatively sparse fossil record that reaches back to the Late Cretaceous (Santonian). The clade was only present in North America during the Cretaceous but spread along unclear routes to Asia and Europe during the Paleocene, only to go extinct on those continents by the end of the Pliocene. Final dispersal to South America took place at some time...
