Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| M. T. Young et al. 2024 | Teleosauroid crocodylomorphs with the following unique combination of characters (4): anterior and anterolateral premaxillary margins are oriented anteroventrally and extend ventrally (125.1); anterior margin of the supratemporal fossae is noticeably inclined anterolaterally (195.1); postorbital extensively forms part of the orbit ventral margin (283.1); palatal ramus of the maxilla takes part in the anteromedial border of the supratemporal fenestra (349.1). |
