Sinosauropteryx
"Sinosauropteryx" was a small theropod with an unusually long tail and short arms. The longest known specimen reaches up to in length, with an estimated weight of It was a close relative of the similar but older genus "Compsognathus", both genera belonging to the family Compsognathidae. Only one species of "Sinosauropteryx" has been named: "S. prima", meaning "first" in reference to its status as the first feathered non-avialian dinosaur species discovered. Three specimens have been described. The third specimen previously assigned to this genus represents either a second, as-yet unnamed species or a distinct, related genus.
Savannasaurus
"Savannasaurus" was a medium-sized titanosaur about in length. The sacrum and the fused ischium-pubis complex are both over one metre in width at their narrowest points, making "Savannasaurus" an unusually wide-bodied titanosaur. In addition to this, the describers identified several other distinguishing characteristics: the first few caudal vertebrae have shallow pits, or fossae, in their sides, a feature that was previously only known among brachiosaurids; the edges of the sternal plates are straight, not kidney-shaped like other titanosaurs; the end of the fourth metacarpal is hourglass-shaped; there is a ridge on the side of the pubis extending forward and downward from the obturator foramen; and the astragalus is taller than it is wide or long.
