Venenosaurus
''Venenosaurus'' ( ; Latin ''venenum'' meaning "poison" and Greek ''sauros'' meaning "lizard") was a sauropod dinosaur, named after the Poison Strip Member of the Cedar Mountain Formation in Utah, United States, where the fossils were discovered by a Denver Museum of Natural History volunteer Tony DiCroce in 1998. ''Venenosaurus dicrocei'' was first described as a new species in 2001 by Virginia Tidwell, Kenneth Carpenter, and Suzanne Meyer.〔 ''Venenosaurus'' is a relatively small (probably around 10 m (33 ft) long) titanosauriform sauropod, known from an incomplete skeleton of an adult and a juvenile. The holotype is DMNH 40932 Denver Museum of Natural History. The specimen consisted of tail vertebrae, the left scapula, right radius, left ulna, metacarpals, forefoot phalanges, right pubis, left and right ischia, metatarsals, chevrons, and ribs.
==Geological and environmental context==
The ''Venenosaurus'' type specimen was found in the Early Cretaceous (Aptian-Albian) Poison Strip Member of the Cedar Mountain Formation in Grand County, Utah.〔 The Denver Museum of Natural History opened a small Cedar Mountain Formation quarry in Eastern Utah.〔 This quarry has produced diverse dinosaur fossils including sauropods, theropods, and ornithopods of varying states of growth.〔 Of the sauropod remains from the quarry only one individual was fully grown.〔 Carbonate growths appear on bones in the quarry from which ''Venenosaurus'' was extracted.〔
