| J. F. Bonaparte 1996 | Sauropod provided with a prominent spinous acromial process in scapula, internally flat, but externally with a rounded ridge running obliquely to scapular longer axis, along the middle of the acromial process. Deep, semicircular separation between acromial process and anterior (dorsal) border of scapular blade. The latter well expanded distally. Acromial depression dorsoventrally elongated. |
