Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M.-C. Buchy et al. 2006 | "A member of the genus Geosaurus characterized by its extremely long and narrow supratemporal fenestra, the length of which reaches about 2.5 times its caudal width. The lateral margins of the supraorbital portion of the frontal are grooved, suggesting that this bone was excluded from the centre of the dorsal margin of the orbit by the prefrontal. The lateral margins of the intertemporal bar are straight, except for the narrow parietal table located in the middle area of the bar." |
