Anchisaurus

ANG-kih-SOR-us name means “Near lizard”

One of the very first dinosaurs — small enough to hold, but built like the giants to come.

Anchisaurus was a member of a very early group of dinosaurs, the prosauropods. These dinosaurs were relatives of the giant plant-eating sauropods. Indeed, many of the sauropod features can be seen in Anchisaurus, such as a long muscular tail, a large, barrel-shaped body, a long neck, and a relatively small head. The five-fingered Anchisaurus and its prosauropod cousins were the first tall dinosaurs able to feed from tall trees, in addition to eating small plants and shrubs.

Small Head, Huge Body

Small Head, Huge Body

Anchisaurus had a rather small, lightweight skull. It had coarsely serrated teeth that it used to saw through stems and leaves. Like other members of the prosauropod family, Anchisaurus had a very small head in proportion to the rest of its body.

Prosauropod Relatives

Prosauropod Relatives

Anchisaurus is shown here with a few of its larger prosauropod relatives. Prosauropods were among the first big plant-eating dinosaurs. Some experts say that these herbivores grew so big because plant-eaters needed larger digestive systems than the meat-eaters of the same period.

MassospondylusThis dinosaur may have a build similar to one of the giant sauropods, but it measured only sixteen feet long. The tail of Diplodocus, one of the biggest sauropods, measured forty-five feet—about three times as long as one Massospondylus!
PlateosaurusThis was one of the earliest dinosaurs, living about 200 million years ago.
