Spinosaurids

The remains of a herbivore dinosaur estimated to have lived around 125 million years ago have been found on the Isle of Wight in England, with scientists believing it is the most complete specimen to have been found in Britain in a century.

The huge African predator Spinosaurus spent much of its life in the water, propelled by a paddle-like tail while hunting large fish - a "river monster," according to scientists, that showed that some dinosaurs invaded the aquatic realm.
