A very rare three dimensional Plesiosaur skeleton, Lower Lias Formation, Lyme Regis, Dorset, approx. 205 million years ago 300cm long. During 1840 one of the first books ever written about prehistoric animals was published. Not only was the volume huge in size, it was given the very dramatic title of The Book of the Great Sea Dragons, and its subject was the fossil Plesiosaurs that had recently been found at Lyme Regis and in nearby places. 21st November, 2017 Evolution Auction
