Alamosaurus was one of the very last sauropods, the huge long-necked dinosaurs that thrived in the Jurassic period. It may have even been one of the very last dinosaurs alive when they were abruptly made extinct about 65 mya. It is one of the very few titanosaurids found in North America, but it is also the most abundantly found, thanks to a large concentration of parts found in 1995.

This dinosaur is an example of how sauropods re-entered North America, after they were extinct there, through South America where titanosaurids were very common.
