Anatosaurus was an amphibian, webbed-hand dinosaur of the Cretaceous period, remains of which were first found in 1942. Anatosaurus was a herbivore, and from extensive remains found including mummified samples with skin connected, we know that it was between 10 and 13 metres long, walked on its hind legs and had forelegs adapted a little like hands, the fingers of which were covered in a webbed skin, presumably to assist in swimming. Anatosaurus had a low, broad skull with a snout similar to a duck's. Research Anatosaurus

Avaceratops were first discovered in 1981 in Montana, USA and were named in 1986 after the wife of the man who found the bones. Avaceratops was a herbivore, about 2.5 metres long, with a short bony frill over the neck, a single short horn on the snout, and walked on all fours. As only one specimen has been discovered, it is impossible to say what size the species really was, the specimen might have been of a juvenile. Research Avaceratops

Barosaurus was a dinosaur of the Jurassic period. Remains of Barosaurus were first discovered in 1890, and have been found in both the western USA and in Tanzania in rocks of the same age - indicating a continual land-mass between the two places in the Jurassic period. Barosaurus was a herbivore, with a big heavy body, about 25 metres long, thick legs and a long neck and tail. Research Barosaurus
