Craspedochelys picteti

Reptilia - Plesiochelyidae

Taxonomy

Craspedochelys picteti was named by Rütimeyer (1873). Its type specimen is NMS 8510 (holotype; formerly NMS 129), a partial shell (left anterior portion of a shell with poorly preserved plastron), and it is a 3D body fossil. Its type locality is Limestone quarry within or around Solothurn, which is in a Kimmeridgian shallow subtidal limestone in the Reuchenette Formation of Switzerland.

It was synonymized subjectively with Plesiochelys etalloni by Gaffney (1975).

Diagnosis

Reference	Diagnosis
J. Anquetin et al. 2017	Craspedochelys picteti differs from all other Craspedochelys by having a carapace with a heraldic shield shape, a greater size (up to 550 mm), a reduced or absent contact between costal VIII and peripheral XI, and a smaller and narrower pygal bone. Craspedochelys picteti further differs from Craspedochelys jaccardi by having a lower length/width ratio of the costal bones (around 4.3, as opposed to 4.8 or more for costal IV), and slightly longer than wide hyoplastra.
