Cetiosaurus vertebra of Kimmeridgian age, approximately 152 to 157 Mya during the Jurassic period. This specimen was collected in Weymouth, Dorset, a location which is well known for its Jurassic fossils. The name Cetiosaurus means ‘Whale lizard’ reflecting its huge size of up to 18 m in length, which is approximately the length of two double decker buses. This giant herbivore is actually one of the more common Jurassic Sauropods. Its vertebra were solid, they had limited air chambers, unlike that of later Sauropods which have hollowed out vertebrae, this indicates that Cetiosaurus was a relatively primitive Sauropod. This vertebra is 12 cm in diameter and 5 cm thick however it has been slightly distorted during compression. Supplied with an information label.
