4.2" Polished Partial Sauropod (Cetiosaur) Bone - England


This is a rare, cut and polished bone of a British sauropod dinosaur, Duriatitan humerochristatus. It was collected from a gravel pit in Abingdon, Oxfordshire, England. The transverse-cutting and polishing of the bone allows for presentation of the bone cell structures and the natural mineralization that occurred, within. You really don't see British or European dinosaur material on the market very often. It comes with an acrylic display stand.

Cetiosaurus meaning 'whale lizard' is a herbivorous sauropod dinosaur from the Middle Jurassic Period of Europe.

Cetiosaurus was in 1842 the first sauropod from which bones were described and is the most complete sauropod found in England. It was so named because its describer, Sir Richard Owen, supposed it was a marine creature, initially an extremely large crocodile, and did not recognise it for a land-dwelling dinosaur. Because of the early description many species would be named in the genus, eventually eighteen of them. Most of these have now been placed in other genera or are understood to be dubious names, based on poor fossil material. The last is true also of the original type species, Cetiosaurus medius, and so C. oxoniensis was officially made the new type species in 2014. C. oxoniensis is based on three more or less complete specimens, discovered from 1868 onwards. Together they contain most of the bones, with the exception of the skull.

Cetiosaurus oxoniensis was a "primitive", quadrupedal, long-necked, small-headed herbivore. It had a shorter tail and neck than most sauropods. The forelimbs on the other hand, were relatively long. C. oxoniensis is estimated to have been about 16 metres (52 ft) long and to have weighed roughly 11 tonnes (12 short tons).
