Diagnosis
ReferenceDiagnosis
L. E. Fiorelli and J. O. Calvo 2007Relatively small, thin and slender crocodyliform, diagnosed by the following combination of poscranial characters: lengthened cervical vertebrae with low ventral keel, parapophysis and diapophysis anteroposteriorly lengthened. Neural spines elongated in dorsal vertebrae, with their centra lengthened without ventral keel but with a very low anterior hypapophysis. Two laterally enlarged sacral vertebrae. First caudal vertebra with a tenuous opisthocoelous and elongated anterior caudal vertebra, relatively low. Scapula with an important dorsal expansion and a good development of the posterodorsal hook. Humerus with a good development of the lateroproximal expansion, long and thin diaphysis of the humerus with the medial condyle biggest than the lateral one. Very lengthened and thin ulna, with olecranon process. Very thin and proximally expanded radius. Thin and long pubis with a very light distal expansion. Non-sigmoid and lengthened femur, smaller than the tibia.
