ABOUT DRYOSAURUS. Dryosaurus was a small bipedal Ornithopod dinosaur from the Late Jurassic Period. Named by paleontologist Othniel Charles Marsh in 1894, its fossil remains have been found in WY - including at our digsite - as well as in Colorado and Utah, and Africa (Tanzania).
The long-necked Dryosaurus had a horny beak and a mouth lined with cheek teeth, which may have allowed the dinosaur to store and chew coarse plant material. Its name --“oak lizard"-- is derived from the oak leaf-like shape of its teeth.
Fast runner. Skeletal remains have revealed that Diplodocus most likely lived in herds and was definitely built for speed. Its long, slim legs were powerfully built, and its long, stiff tail provided a counterbalance for changing direction quickly when being pursued.
Lithe and agile. A small, slim and agile herbivore, adult Dryosaurus grew to a length of up to 10 feet, stood 5 feet tall at the hips and weighed close to 200 lbs.
