The amazing “Jurassic Coast” in Dorset/Devon has thrown up another fantastic fossil – the skull of a massive pliosaur, which would have been perhaps 15m long. To be honest, the fossil isn’t much to look at (a load of rock), but it’s a pretty impressive find. Pliosaurs, in case you don’t know, were short-necked marine reptiles. Together with their relatives the plesioaurs (with long-necks, which look like the Loch Ness Monster) they ruled in the seas up until shortly before the end of the Cretaceous. There’s a great fossil plesiosaur and a model in the Manchester Museum. And no, they were not dinosaurs, which neither flew nor swam.
