Alamosaurus

Alamosaurus, (meaning "alamo lizard"), was a quadruped herbivore, and was named after Fort Alamo, Texas. Alamosaurus, measured to be one of the last of the sauropods, lived 80 million years ago through the late Cretaceous period.

Gilmore named it in 1922 after partial skeletons were establish and was the first sauropod of the family Titanosauridae to be found in North America. Alamosaurus fossils have been improved from Montana, New Mexico, Texas and Utah, though no complete skulls have been found. The animal had a long neck, and a whip-like tail, probably used to protect itself against predators. Although little evidence has been found, some scientists say Alamosaurus may have had body Armour, like other sauropods at the time.

It is estimated that Alamosaurus weighed approximately 33 tons and was over 69 feet long, much larger than other members of the Titanosauridae. The most recent major Alamosaurus discover consists of two huge bones, a shoulder bone and a humerus from the Big Bend National Park, in the 1970's.
