The Palaeozoic was a time of huge change for Scotland. It travelled across the Southern Hemisphere from the region of the South Pole, to north of the equator. During the Ordovician Scotland constituted an ocean floor, yet during the Devonian it was dominated by a mountain range of alpine proportions. It was also witness to the Cambrian’s ‘explosion’ of life on Earth, and by the Permian was a landmass on which early dinosaurs lived.
