Diagnosis
Reference | Diagnosis | |
---|---|---|
R. Allain and N. Aquesbi 2008 | Gravisauria is a node-based taxon defined as the most recent common ancestor of Tazoudasaurus and Saltasaurus Bonaparte & Powell, 1980 and all its descendants. This definition encompasses the older definition of Sauropoda (McIntosh 1990). Gravisauria is diagnosed by two unambiguous and non-homoplastic synapomorphies: the dorsal neural spines which are broader transversely than anteroposteriorly, and the asymmetry of the femoral distal condyles, with a broader tibial condyle.
