- Camptosaurus dispar
- Jurassic AgeMorrison Formation
- Bone Cabin Quarry
- Washakia County, Wyoming
- Specimen measures approx. 4″ long x 4 3/4″ tall. This specimen has had a small amount of crack repair/restoration which is expected when dealing with Jurassic Age Bones!! The work has been expertly done and is difficult to detect. This specimen is way above average for Jurassic Dinosaur material!!! It will come with the custom made stand as shown and ID Tag as shown.
Camptosaurus is a genus of plant-eating, beaked ornithischian dinosaurs of the Late Jurassic period of western North America and possibly Europe. The name means ‘flexible lizard’. Camptosaurus is a relatively heavily built form, with robust hindlimbs and broad feet, still having four toes. Due to the separate status of Uteodon it has become problematic which material from the Morrison belongs to Camptosaurus. The specimens with certainty belonging to Camptosaurus dispar, from Quarry 13, have been recovered from very deep layers, probably dating to the Callovian-Oxfordian. The largest fragments from later strata indicate adult individuals more than 7.9 metres (26 ft) long, and 2 metres (6.6 ft) at the hips. The Quarry 13 individuals are smaller though. They have been described as reaching 6 meters (19.7 feet) in length and 785 – 874 kg in weight. In 2010 Gregory S. Paul gave an even lower estimate: a length of five metres and a weight of half a tonne. The skull was triangular with a pointed snout, equipped with a beak. Its teeth were more tightly packed in the jaw
compared to other Morrison euornithopods. Museum curator John Foster describes them as having “thick median ridges on their lateral sides and denticles along their edges,” these features were similar to, but “more fully developed” than those in Dryosaurus. Camptosaurus teeth frequently exhibit extensive wear, which indicates that individuals in the genus had a diet of relatively tough vegetation.
