During the Triassic period, the parts of Pangaea which now constitute Britain drifted from the equator to more or less its current location. But with the break-up of the prehistoric supercontinent, ‘Britain’, which had spent much of the Permian underwater, dropped below sea-level once more. And although that is where it spent most of the Jurassic and Cretaceous, there were periods when the land was above sea-level, some of which lasted for as many as twenty million years.
And during those dry years, dinosaurs walked the land. Not just any dinosaurs – but, as recent fossil evidence reveals, robot dinosaurs!
