Diagnosis
ReferenceDiagnosis
M. T. Young et al. 2024Teleosauroid crocodylomorphs with the following unique combination of characters (5): between 50% and 65% of the premaxilla total length is posterior to the external nares (shared with Teleosaurinae) (127.1); orbit longitudinal ellipsoidal in shape (reversal in Machimosaurini) (shared with non-crocodylomorphs sampled; the early diverging crocodylomorph Carnufex; the shartegosuchoid Sichuanosuchus; the early diverging thalattosuchian Plagiophthalmosuchus; the teleosauroids: the unnamed Chinese teleosauroid, Platysuchus, Seldsienean, and Aeolodon; the metriorhynchoid clade Eoneustes + Metriorhynchidae; the pholidosaurid Pholidosaurus purbeckensis; and the hylaeochampsids Pietraroiasuchus and Iharkutosuchus) (273.1); basisphenoid cultriform process exposed on the palate anterior to the quadrates (451.1); retroarticular process oriented posteriorly (reversal in Lemmysuchus and Yvridiosuchus) (568.1); humerus proximal region very strongly deflected posteriorly and hooked (shared with Aeolodon) (753.2).
