 Much of the Midlands and north of England may have been covered by Jurassic and Cretaceous deposits at the start of the Palaeogene, but lost them through erosion.By 35 million years ago, the landscape included beech, oak, redwood and palm trees, along with grassland.In the Miocene and Pliocene epochs of the Neogene period, further uplift and erosion occurred, particularly in the Pennines.
