Alamosaurus
With its long neck and whippy tail, Alamosaurus looks much like any other sauropod. However, it is rare because it is the only type of sauropod to be found in North America at this time. A long way from home? Sauropods are the giants of the dinosaur age. The biggest animals to have walked on land, the sauropods peaked during the Jurassic period. By the late Cretaceous period, they had disappeared from North America, apart from Alamosaurus, who can be found in Texas, Utah and New Mexico. Some palaeontologists believe that these dinosaurs wandered up from South America, where more sauropods may still be found.
Bulky body
The largest sauropods, like Brachiosaurus (BRA-kee-o-SORE-us), are about 16 metres (53 feet) high and weigh over 80,000 kilograms (88 tons). Although Alamosaurus is much smaller, it’s still big enough! Remarkably, it can even stand on its hind legs to feed on tasty leaves that might otherwise be out of reach.
