Apatosaurus or “deceptive lizard” is a genus of herbivorous sauropod dinosaur that lived in North America during the Late Jurassic period.

Apatosaurus was a large, long-necked, quadrupedal animal with a long, whip-like tail. Its forelimbs were slightly shorter than its hind limbs. Most size estimates are based on specimen CM 3018, the type specimen of A. louisae. In 1936 this was measured to be 72 ft.

The skull is small in relation to the size of the animal. The jaws are lined with chisel-like teeth suited to an herbivorous diet. The snout of Apatosaurus and is squared. The braincase of Apatosaurus is well preserved in specimen BYU 17096, which also preserved much of the skeleton.

Some skulls of Apatosaurus have been found still in articulation with their teeth. Those teeth that have the enamel surface exposed do not show any scratches on the surface; instead, they display a sugary texture and little wear.

The limb bones are also very robust. The arm bones are stout, so the humerus of Apatosaurus resembles that of Camarasaurus, as well as Brontosaurus. Apatosaurus had a single large claw on each forelimb. The first three toes had claws on each hindlimb. The single manual claw bone (ungual) is slightly curved and squarely truncated on the anterior end.

The pelvic girdle includes the robust ilia, and the fused (co-ossified) pubes and ischia. The femora of Apatosaurus are very stout and represent some of the most robust femora of any member of Sauropoda.
