Cet extrêmement rare squelette de reptile sauropterygian, un reptile marin, a été découvert au début des années 90 dans une concrétion sur la carrière de Blockley, Gloucestershire, Angleterre. Le squelette se situait dans la zone Davoei du Bas Lias et dispose approximativement d'un âge de 190 millions d'années. Ce plesiosaure, demeure en l'état de nos connaissances, le meilleur et le mieux préservé de tous les spécimens trouvés. En effet, il dispose d'un thorax complet, de parties de la queue, du cou, des membres et même du fragile crâne. Les plésiosaures furent un genre de reptiles aquatiques connus tout autour du monde de la période du bas triassique jusqu'au bas crétacé. Actuellement, les connaissances scientifiques accumulées indiquent que les plésiosaures étaient des reptiles prédateurs extrêmement rapides. Ils chassaient tout aussi bien des poissons que des calamars. Un spécimen trouvé au Kansas gardait encore dans son corps des gastrolithes tant l'animal avait besoin de ces pierres pour broyer la nourriture à l'intérieur de l'estomac comme les crocodiles le font encore aujourd'hui. Les Cryptocleidus et d'autres membres de cette famille ont conservé le nez relativement court du Plésiosaure. Ils ont développé, cependant, beaucoup de dents incurvées et pointues pour filtrer de plus petits poissons et crevettes, ceci même avec la bouche fermée dans l'eau. Comme d'autres plésiosaures jurassiques, Cryptocleidus a disposé dans chacun de ses cinq doigts de plus d'os que les reptiles terrestres, lesquels ont facilité la formation de longues et flexibles palettes. Dans l'imagination populaire, le monstre du Loch Ness prend l'apparence d'un plésiosaure. Les localités les plus importantes pour la découverte de fossiles de ces créatures sont les dépôts jurassiques de Holzmaden en Allemagne du sud et le Dorset en Angleterre. On indiquera enfin que les plésiosaures complets sont exrêmement rares. Les premiers fossiles de plésiosaures d'Angleterre ont été trouvés par Lary Anning (1799-1847) dans les premières années du XIXe siècle et ces découvertes sont maintenant dans la célèbre collection du Musée d'Histoire Naturelle de Londres. Il s'agit donc, à notre connaissance, du seul et rare squelette de Plésiosaure, Cryptocleidus sp, encore en mains privées.
This extremely rare sauropterygian skeleton, a marine reptile, was discovered in the early 90's in a calcareous concretion in the Blockley quarry, Gloucestershire, England. The skeleton was in the area of the lower Lias, Davoei, and is approximately 190 million years old. To our knowledge, this Plesiosaur is the best preserved of all found specimens. It possesses a complete chest, parts of the tail, neck, limbs and even the fragile skull. The plesiosaurs were a kind of aquatic reptile from the lower Triassic to the lower Cretaceous period, known all over the world. Currently, the scientific knowledge that has been gathered indicates that the plesiosaurs were extremely fast predatory reptiles. They hunted fish as well as squid. A specimen found in Kansas still retained gastroliths in the body of the animal, as the animal needed to grind food within the stomach like crocodiles do today. The Cryptocleidus and other members of the same family have retained the plesiosaurs' relatively short nose. However, they developed a large number of curved and pointed teeth for filtering the smallest fish and shrimp, even with their mouth closed in water. Like other Jurrasic plesiosaurs, each ot the Cryptocleidus' five fingers contained more bone than terrestrial reptiles, whose were long and flexible. In popular imagination, the Loch Ness monster assumes the appearance of a plesiosaure. The most important localities for the discovery of these creatures' fossils are the Jurassic deposits of Holzmaden in south Germany and Dorset in England. One final thing to point out is that complete plesiosaurs are extremely rare. The first plesiosaur fossils in England were found by Lary Anning (1799-1847) in the first few years of the 19th century, and these discoveries are now part of the famous collection of the Natural History Museum in London. To our knowledge this is the rare and only skeleton of a Cryptocleidus Plesiosaur that still remains in private possession.
