Ampelosaurus (am-PELL-oh-SORE-us) was a medium-sized sauropod from the Late Cretaceous Period in what is now France.

The body osteoderms embedded in the skin of this animal's seem to have been a common of many titanosaurs, and some were much more heavily armored.

Discovery and naming

In 1989 a team of French paleontologists were digging in a bonebed called Compagne-sur-Aude when they came across very large limb bones, vertebrae, and ribs. They were found in the levels of the Marnes Rouges Formation and were from the Cretaceous period.


They were sent to a museum and forgotten about until in 1995 a French paleontologist named Jean Le Loeuff was digging in a vineyard in Southern France when he came across some very large bones.

He knew right away they belonged to sauropod and sent them in for study. They were found to belong to the same kind of dinosaur that was found in 1989. It was unnamed until that time so Le Loeuff decided to name it Ampelosaurus, or "vine lizard", after the vineyard he found it in. This fossil find has made it one of the most popular dinosaurs from France. This sauropod is a significant find because it's one of the only known sauropods that lived during the Late Cretaceous besides Alamosaurus.


Ampelosaurus was a type of sauropod, meaning it was a long-necked, very large dinosaur that walked around on four thick but slow legs.

It was a type of titanosaur, some of the biggest dinosaurs that ever walked the Earth. It was closely related to Saltasaurus from South America. Like other sauropods, it was a herding animal and had a small head. It also ate over a tons of vegetation a day and with the help of gastroliths was able to digest it within its huge gut. It grew to be about 50 feet (15 meters) long and over 10 tons in weight. It's tail was very long and was robably used for defense to whip at predators like the fearsome Tarascosaurus and deadly Pyroraptoror possibly against rivals. One feature that sets it a bit apart from most other sauropods is that it had armor-like plating that ran all the way down its back to the beginning of the tail.

It's not quite known why this is so, but it could be for extra protection against the powerful jaws of the predatory abelisaurids that it shared its habitat with.

Ampelosaurus Brain Size

Another strange fact about Ampelosaurus is that a species that's four times smaller than it has been found in bonebeds on islands around Europe. This is probably caused by island dwarfism, which is caused when a group of animal species has been trapped on an island and over time they grow smaller to survive on the smaller food and water rations that are on the island. This has also been found with dinosaurs that lived in the same area as it, such as Tarascosaurus, Pyroraptor, Iguanodon, and even Troodon. A recent study seems to show just how unintelligent sauropods truly were when scientists CAT-scanned the skull of Ampelosaurus and found it to be no bigger than the size of a tennis ball, so if brain-to-body size ratio showed how intelligent an animal was, then that makes sauropods very low on the IQ charts.
