Alamosaurus (meaning "Ojo Alamo lizard") was an American titanosaur. It was found in Texas. It was named after Ojo Alamo, a formation in Texas, where it was first discovered. It was the last sauropod known from North America, and may well have been prey to Tyrannosaurus. It was one of the last Sauropods. The name Alamosaurus means "Lizard from the Alamo". It was about 56–98 feet long and weighed about 88 tons.

A skeleton of Alamosaurus stood in what was once the Visitor Center of the original Jurassic Park along with a neighboring Tyrannosaurus rex skeleton.[1] [2]Alan, Ellie, Lex, and Tim attempted to use it to climb down from the ceiling to escape a member of the Velociraptor pack, who's attack caused the skeleton to fall apart. [3]

Behind the scenes

When the Visitor Center appears in other Jurassic Park media, Alamosaurus is often replaced by diplodocid sauropods such as Apatosaurus (LEGO Jurassic World) or Brontosaurus (Jurassic Park Discovery Center).
