Alamosaurus is a titanosaur from the late-cretaceous period of North America, around sixty-six-million-years-ago.
Alamosaurus is from the sauropod lineage that possess armor, though Alamosaurus itself has not given any indication of having armor.
It is considered the youngest sauropod of North America, possibly originating from South America where titanosaurs are more common.
