Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. Anquetin et al. 2017 | Idiochelys fitzingeri can be diagnosed as a “eurysternid” by the full list of characters provided for that taxon above: thin-shelled and small to moderately sized (carapace length 200 to 400 mm), by the presence of a ligamentous bridge and lateral plastral fontanelles, and a tendency toward the reduction of sutural contacts between the hyoplastra and the anterior plastral elements. |
