Calcarichelys ('spur turtle' or 'thorn turtle')[1] is an extinct genus of protostegid turtle from the Late Cretaceous of the Selma Formation in Alabama, and possibly from Angola.[2][1][3][4] It contains only one species, C. gemma.[3][5]
Discovery
The holotype specimen of Calcarichelys is known from Mooreville Chalk, Alabama.[1] More complete specimens are later described from same formation.[3] Another specimen that possibly belongs to Calcarichelys or related species is known from the Maastrichtian of Bentiaba, Angola.[4]
Description
Calcarichelys is a small protostegid, with a carapace length of 25.3 cm (10.0 in).[3] It is probably closely related to Chelosphargis, as they share some characteristics.[1][3] Unlike Chelosphargis, Calcarichelys is characterized by thorn-like neural plates.[1][3]
