Diagnosis
ReferenceDiagnosis
J. F. Bonaparte 1986Cetiosaurid of large size, with tall dorsal vertebrae; posterior dorsals with elevated neural arches and well-developed neural spines, formed from 4 divergent laminae and with a massive dorsal region; dorsoventrally-oriented neural spine cavities, more expanded than in Barapasaurus. Anterior and lateral regions of the neural arch similar to that of Cetiosaurus and Barapasaurus. Sacrum with 5 vertebrae, elevated neural spines, and a large dilation of the neural canal forming a neural cavity. Pelvis with pubis showing distal and proximolateral expansions, more developed than in Barapasaurus, and a less expanded pubic symphysis than in Amygdalodon. Ischium slightly transversely compressed, with a ventromedial ridge of sublaminar type, and with a clear distal expansion. Ratio of tibia-femur lengths from 1:1.5 in juveniles, reaching 1:1.7 in adults. Mandible with weak medial torsion. Spatulate teeth with occlusal traces. (Translated by M. Carrano.)
