Cedarosaurus ("Cedar lizard") is a genus of dinosaur from the Lower Cretaceous ( Barremium ) of North America and belonged to the medium-sized Brachiosauridae . In the genus that belongs to the sauropods, only the type species Cedarosaurus weiskopfae has been placedso far.
Fossils of this animal were discovered in what is now the US state of Utah . The dinosaur was about 20 meters long, about 10 meters high (head height) and weighed an estimated 40 tons. This information is inaccurate, however, since Cedarosaurus has so far only found the incomplete skeleton of a single individual ( holotype DMNH 39045). Like all sauropods , Cedarosaurus walked on four legs and was a herbivore. Typical of a brachiosaurid were the front legs, which were longer than the rear legs, and a "hump" on the skull with the nostrils on the front.
The species Cedarosaurus weiskopfae was discovered in 1999 by the paleontologists Virginia Tidwell , Kenneth Carpenter and William Brooks . They named the genus after its location in the Cedar Mountain Formation (Yellow Cat Member), the species epithet honors the deceased Carol Weiskopf.
