Its type locality is Limestone quarry within or around Solothurn, which is in a Kimmeridgian shallow subtidal limestone in the Reuchenette Formation of Switzerland.

Diagnosis
ReferenceDiagnosis
J. Anquetin et al. 2017Craspedochelys 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.
