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

Gilmore named it in 1922 after partial skeletons were found and this was the first sauropod of the Titanosaurus Dinosaurs family to be found in North America.

Alamosaurus Dinosaur fossils have been found from Montana, New Mexico, Texas and Utah but no complete skulls have ever been found. This 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 was estimated that Alamosaurus dinosaurs weighed approximately 33 tons and 69 feet in length which was much larger than other members of the Titanosauridae. The most recent major Alamosaurus discovery consisted two huge bones, a shoulder bone and a humerus from the Big Bend National Park, in the 1970's.
