Ampelosaurus ampihloh-SƆːRUHS

Ampelosaurus ( ; meaning “vine lizard”) is a titanosaurian sauropod dinosaur from the Late Cretaceous Period of what is now France. Its type species is A. atacis, named by Le Loeuff in 1995. Its remains were found in a level dating from 71.5 million years ago, representing the early Maastrichtian.

Ampelosaurus would have had a long neck and tail — like most sauropods — but it also carried armor in the form of osteoderms. In 2005, over 500 bones had been assigned to Ampelosaurus. Additional material has been found since, including a partially articulated skeleton with skull, which makes it one of the best known dinosaurs in France. However, recent studies suggest that the type locality is not a monospecific titanosaur bone bed and that part of the bones attributed to Ampelosaurus probably belong to a second titanosaurian taxon.
