Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. Anquetin et al. 2017 | Jurassichelon can be diagnosed as a thalassochelydian by the full list of characters provided for this clade above. Juras- sichelon is differentiated from all other thalassochelydians by medium size (350 to 400 mm in carapace length), the presence of reduced costo-peripheral fontanelles, distally thinning costal bones, vertebral scutes that cover about half of the costals, a mostly ligamentous contact between the hyoplastron and the epi- and entoplastron, and the presence of a small xiphiplastral notch. |
