Sauropods evolved from prosauropod ancestors, that is, prosauropods were ancestral to saurpods.
The pleurocoels in sauropodomorph vertebrae may have contained air sacs.
Sauropods are divided into several clades including the basal “cetiosaurids” and Camarasaurids, Diplodocids, Titanosaurids and Brachiosaurids.
Sauropod skeletons are often found missing their heads, parts of their tails and their feet.
The heads, the feet and parts of the tails are often found missing from sauropod skeletons.
Although a new study suggests that really long-necked sauropods like Diplodocus probably didn’t lift their heads high above the ground, this is not the case for Brachiosaurus.
Sauropods are noted for their great chewing ability.
Seismosaurus may have choked on an extra large gastrolith that it attempted to swallow, a gastrolith that it needed because sauropods are not noted for their great chewing ability.
Many sauropodomorphs lived in herds that migrated large distances.
The dinosaur depicted in the overhead projection is Plateosaurus.
