Biology:Fontainechelon
Fontainechelon is an extinct genus of testudinid from Saint Papoul, France during the Early Eocene. It is known from a single species, F. cassouleti.[1]
Fontainechelon is the oldest European testudinid, and the most basal of all testudinids.[1][2]
Etymology
It was named after Jean de La Fontaine, alluding to some of his fables in which the protagonist was a tortoise.
Taxonomy
Fontainechelon cassouleti was historically considered a species of Achilemys. The genus Achilemys is now restricted to North America.[1] Fontainechelon was found to be the most basal of all testudinids.[1][2]
Description
The species is known primarily from the holotype, which includes a partial carapace, a complete plastron, the right humerus, and the left femur. There are also several highly fragmentary referred specimens. The holotype had an estimated shell length of 37 cm.[1]
