Cetiosaurus (SEET-ee-oh-sawr-us) meaning 'whale lizard', from the Greek cetus/κητος meaning 'sea monster' (later, 'whale') and saurus/σαυρος meaning 'lizard', was a sauropod dinosaur from the Mid to Late Jurassic Period (181-169 million years ago) in what are now Europe and Africa. It is estimated to have been about 53 feet (16 m) long and to have weighed roughly 24.8 tonnes (27.3 short tons). It was so named because its discoverer, Sir Richard Owen supposed it was a marine creature, initially an extremely large crocodile.

| - 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).

Los Cetiosaurus formaban grandes manadas que recorrían enormes distancias en busca de comida. Normalmente vivían cerca de los lagos donde su peso se reducía un poco y podían alimentarse de plantas acuáticas gracias a sus dientes en forma de rastrillo. Se cree que estos animales se alimentaban casi exclusivamente de plantas acuáticas. Los Cetiosaurus tragaban piedras que solían buscar cerca de los lagos donde pasaban gran parte del día, y el hecho de encontrar piedras originarias de otros lugares encontradas en estos dinosaurios incluso a 100 km de su lugar de origen sugiere que estos dinosaurios hacían enormes migraciones.
