Lincolnshire reaching between 4.7 and 5.3 on the Richter magnitude scale; it was one of the largest earthquakes to affect Britain in recent years. Lincolnshire is home to Woolsthorpe Manor, birthplace and home of Sir Isaac Newton. He attended The King's School, Grantham. Its library has preserved his signature, carved into a window sill when he was a youth. Bedrock in Lincolnshire features Jurassic limestone (near Lincoln) and Cretaceous chalk (north-east). For much of prehistory, Lincolnshire was under tropical seas, and most fossils found in the county are marine invertebrates. Marine vertebrates have also been found including ichthyosaurus and plesiosaur .
