Diagnosis

Reference	Diagnosis
J. E. Powell 1992	Titanosaurs of medium size, smaller than those in the remaining subfamilies. The skull with basal tubera fused medially. The supratemporal fenestra is closed. There are complex triangular basipterygoids with a prominent sagittal crest. The fenestra ovalis is open for the passage of nerves IX-XI. The foramina for the internal carotids are situated medially and anterior to the basipterygoids. The pleurocoels on the centra of the cervical and dorsal vertebrae are reduced. The cervical vertebrae are shorter and more robust than those of the Titanosaurinae. The neural spine of the dorsals is extremely thick and rounded. The centra of the caudal vertebrae are broader than tall, with variable development of spongy bone. The spines of the caudal vertebrae are posteriorly inclined, spines of the anterior vertebrae are low. Medial prominence is close to the upper edge of the scapula. There is a broad pelvis with ilia whose preacetabular process is extended laterally.
