Saurischians are divided into 2 definite clades: Sauropodomorpha
& Theropoda (although it is not clear what to do with Segnosauria).
Theropoda & Sauropodomorpha are the 2 definite clades into
which saurischians are divided, although it is not clear what
to do with Segnosauria.
Although it is not clear what to do with Segnosauria, saurischians
are divided into 2 definite clades: Sauropodomorpha & Theropoda.
Prosauropods were ancestral to saurpods, that is, sauropods
evolved from prosauropod ancestors.
Sauropods evolved from prosauropod ancestors, that is, prosauropods
were ancestral to saurpods.
Sauropods are divided into several clades including basal form, "cetiosaurids" and Camarasaurs & Titanosaurs.
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.
The pneumatic openings in sauropod bones have nothing to do with sauropod breathing; that is, sauropod bones definitely did not hold air sacs and sauropods definitely did not have unidirectional airflow in their lungs, like birds.
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 .
