Its body was at least partly covered in bony armor. Among other sauropods, Alamosaurus may get lost among more its famous cousins.Īlamosaurus was a gigantic quadrupedal herbivore with a long neck and tail and relatively long limbs. This sauropod will make a notable inhabitant of any Late Cretaceous themed exhibits, alongside Edmontosaurus, and Triceratops. Presumably these would have once been arid plains that both animals would have traversed on migratory routes between the coasts of the Pacific Ocean and the inland sea.Īlamosaurus is fairly well known dinosaur to science, though a skull has yet to be found. Alamosaurus fossils are common across America, showing it was a very successful animal, with a few areas in Texas dominated by Alamosaurus and Quetzalcoatlus fossils.
Depressions found in the skin suggests it had armor similar to that of its Argentinian relative Saltasaurus. Alamosaurus was an advanced sauropod, with a long upward neck and relatively long legs, suggesting it could move at a brisk pace.
However the discovery of Alamosaurus showed that titanosaurs were not just confined to the southern continents. Alamosaurus is a member of the titanosaur family, a group of sauropods that evolved in the Cretaceous in areas throughout the southern hemisphere South America, India, Madagascar, Egypt and Australia.
However, some evidence point to Alamosaurus being even larger, possibly the largest animal from North America. Alamosaurus is a large dinosaur, but the fossils found are rather medium compared to some other members of the sauropod family such as Diplodocus. Alamosaurus is a large herbivorous dinosaur from Late Cretaceous North America and was among the last dinosaurs present until the Cretaceous extinction.
