Fun Facts about Alamosaurus

Alamosaurus in the forest

Alamosaurus is the only sauropod discovered to far that lived in what is now North America during the late Cretaceous epoch. It is also thought to be one of the final huge sauropods before the Cretaceous mass extinction.

In 1922, explorer Charles Whitney Gilmore reported a shoulder blade (scapula) and a pelvic bone (ischium) of this dinosaur. Then, in 1946, he discovered a more complete fossil in the state of Utah, consisting of a whole tail, a right front leg – complete except for the tips of the toes – and both pelvises ( ischium ).

Since then, numerous other sections of Texas, New Mexico, and Utah have been attributed to the Alamosaurus, frequently without appropriate description. The most complete find is a skeleton of a juvenile Alamosaurus unearthed by Lehman and Coulson in Texas in 2002, which allowed estimates about the length and mass of an adult species to be formed. Isolated vertebrae and limb bones reveal that Alamosaurus was roughly the size of Argentinosaurus and Puertasaurus, making it the largest dinosaur from modern-day North America.
