Which dinosaurs lived in Britain 70 million years ago?

Only two dinosaurs are known to have been in Britain 70 million years ago from the available evidence. Incomplete remains of an armoured dinosaur (ankylosaur) called acanthopholis and a single tooth of a duck-billed dinosaur (hadrosaur), were both found within chalk rock in southern England. In that era, the land that made up the British Isles was isolated from Europe and North America and mostly covered by seas. Marine sediments that turned into chalk rocks were laid down in southern England and the two dinosaur records provide evidence that at least one hadrosaur and one ankylosaur were living on the land areas. There were many dinosaurs living in North America 70 million years ago and quite a few in Europe.
