ABELISAURUS (OT)
(pronounced ay-bel-uh-SAWR-us) Abelisaurus (meaning "Abel's lizard") was a primitive theropod (a bipedal, meat-eating dinosaur) that was roughly 21 to 25 feet (6.5 to 8 m) long, weighing roughly 1500 kg. It lived during the late Cretaceous period, 70 million years ago, in what is now Patagonia, Argentina. It is known from a 35 inch (90 cm) long incomplete skull named in honor of Robert Abel (director of the Argentinian Museum of Natural Science) and was named by paleontologists F. E. Novas and J. F. Bonaparte in 1985. The type species is A. comahuensis. ABRICTOSAURUS
(pronounced uh-BRICK-tuh-SAWR-us) Abrictosaurus (meaning "awake lizard") was a heterodontosaurid (an ornithischian), a bipedal, plant-eating, long-tailed dinosaur that was roughly 4.6 feet (1.2 m) long and weighed about 43 kg. It had high-crowned teeth and lived during the early Jurassic period. Unlike other heterodontosaurids, it lacked canine-like teeth on its lower jaw. It is known from a skeleton and skull found in Lesotho, S. Africa and was named by paleontologist J. A. Hopson in 1975.
ABROSAURUS
(pronounced AB-roh-SAWR-us) Abrosaurus was a sauropod, a long-necked, plant-eating dinosaur. It had a bulky body, column-like legs, and a small head with a nasal crest; the nostrils were almost above the eyes. It lived during the early Cretaceous period. Abrosaurus was named by paleontologist Ou in 1986. It is known from fossils found in China. The type species is A. gigantorhinus (meaning "giant snout"). Very little is known about this dinosaur. |
