Diagnosis
ReferenceDiagnosis
M. Delfino et al. 2005A basal gavialoid that can be differentiated from any other crocodylian by the following combination of characters: an unusually enlarged foramen aereum, dentary alveoli arranged in couplets, evident “quadrate crest” ventrally developed at least on quadrates and pterygoids, nasals reaching and deeply entering between premaxillae, W−shaped basioccipital tuberosity. A further peculiarity could be represented by the presence of an unusual “step−like” widening of the orbital margin of prefrontal.
