Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. T. Young et al. 2024 | Thalattosuchian crocodylomorphs with the following unique combination of characters (13): external and internal antorbital fenestrae are subequal or not distinguishable (169.0); supratemporal fenestrae longer than the orbits (198.2); squamosal does not project further posteriorly than the occipital condyle (reversal in the unnamed Chinese teleosauroid) (249.0); orbits have a dorsal inclination (271.1); in palatal view, the maxilla projects anteriorly with straightened margins creating a sub-rectangular shape (353.2); consistent presence of occipital tuberosities (410.1); within the trigeminal fossa, the foramina are fully divided into two openings by a bridge formed by proötic, dorsal opening interpreted as rostral middle cerebral vein and ventral opening as exit for trigeminal branches (441.1); paired ridges present on the medial ventral surface of the basisphenoid (449.1); main body of the quadrates are strongly inclined (464.2); first and second premaxillary alveoli form a couplet (reversals present within Teleosauridae) (584.1); third dentary tooth occludes against the premaxilla–maxilla suture (635.0); coracoid with a fan-shaped distal end and a triangular-shaped proximal end (741.1); scapular blade is less than 1.5 times the width of the scapular shaft (shared with the unnamed Toarcian metriorhynchoid) (744.1). |
