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]
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]
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]
