Sur quelques Castorides du bassin d'Aquitaine

Abstract

Fossil Castoridae, except for isolated fossil teeth, are little known in the Aquitaine basin of southwestern France. Recent discoveries at Sansan suggest a fairly large population, and a possible evolutionary relationship between Steneofiber viciacensis, S. depereti, and S. jaegeri involving a progressive simplification of the crown of molar teeth.

Denudation history and palaeogeography of the Pyrenees and their peripheral basins: an 84-million-year geomorphological perspective

“…The Aquitaine Basin also turns out to be an extremely rich repository of continental fossils, with an inventory of several hundred sites -whether in fluvio-lacustrine stratified context or in a karst setting. Some of these are benchmark sites used in the indexation of Paleogene (MP) and Neogene (MN) biozones of the ELMA scale (Richard, 1948;Crouzel, 1957;Bergounioux and Crouzel, 1960;Sudre et al, 1992;Duranthon, 1991Duranthon, , 1993Muratet and Cavelier, 1992;Antoine et al, 1997Antoine et al, , 2011Duranthon and Cahuzac, 1997;Astruc et al, 2003;etc.). The most significant among these reference sites, however, are situated in the distal, often lacustrine molasse deposits of the basin.…”

The last of the large-sized tortoises of the Mediterranean islands

“…The taxonomy of large and giant fossil tortoise species has been puzzling for decades, and only recently have we started to understand their true diversity and their relationships. Historically, all giant tortoise species were considered as members of Testudo Linnaeus, 1758 (a name now restricted to five extant species and their closely related, extinct taxa; TTWG, 2021), like the majority of other tortoises, and were later transferred into other 'wastebasket genera', in particular Cheirogaster Bergounioux, 1935 andGeochelone Fitzinger, 1835 (Bergounioux, 1935;Hummel, 1935;Kuhn, 1964;Auffenberg, 1974;de Broin, 1977;Fritz & Bininda-Emonds, 2007;Georgalis & Kear, 2013;Luján et al, 2014;Vlachos et al, 2014).…”
