Yayitya: InyamaIiplesiosauriiJurassic ephakathi ukuya ku-iCretaceous yokuqalaNgokwenene ayisiyo dayinaso

Cryptoclidus was a medium-sized plesiosaur that swam in warm seas during the Middle and Late Jurassic. It had a small head, a long neck, and four flippers. It probably ate soft animals like squid and small fish.1

izinto ezimnandi

Iinyani ezimnandi

The name Cryptoclidus means 'hidden collarbone' because its collarbones are tiny and hidden in the shoulder area.1

Fossils of Cryptoclidus have been found in the Oxford Clay of Cambridgeshire, England, and in the Kimmeridge Clay of France.1

The type species was first called Plesiosaurus eurymerus, which means 'wide thigh bone', because scientists mistook a front flipper bone for a back leg bone.1

Cryptoclidus had a small, fragile skull and teeth that could not handle tough prey, so it ate only soft animals.1

Scientists think Cryptoclidus used its long, intermeshing teeth to strain small animals from the water or sift through mud.1

The size and shape of its nostrils suggest Cryptoclidus could smell chemicals in seawater, helping it find food.1

Complete skeletons of Cryptoclidus have been found, including some that are nearly entirely preserved, showing both adults and juveniles.1

Umfanekiso owenziwe yi-AI: Cryptoclidus — Umfanekiso owenziwe yi-AI obonisa indlela Cryptoclidus esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

ubuzile

Eyona mibuzo ibuzwa kakhulu: Cryptoclidus

?How big was Cryptoclidus?

About 4 metres long and weighed around 737 to 756 kilograms. That is about as long as a small car.1

?What did Cryptoclidus eat?

It ate small, soft animals like squid and small fish. Its fragile teeth could not handle tough prey.1

?Was Cryptoclidus a dinosaur?

No, it was a plesiosaur, which is a marine reptile that lived in the sea. It is not a dinosaur.1

?When did Cryptoclidus live?

It lived during the Middle and Late Jurassic Period, about 166 to 160 million years ago.1

?Where were Cryptoclidus fossils found?

Fossils have been found in England, France, Cuba, and Russia. Many come from the Oxford Clay in Cambridgeshire, England.1 2

?Could Cryptoclidus swim?

Yes, it was a good swimmer. It used its four flippers to move through warm Jurassic seas.1

Inyaniso ngeentsomi

Intsomi: Some people think Cryptoclidus was a dinosaur.

Inyaniso: Cryptoclidus was a plesiosaur, a marine reptile that lived in the sea, not a dinosaur.1

Kwiingcali zeedayinaso

Igama lenzululwazi: Cryptoclidus
Inikwe igama ngu:: (Seeley 1892)2
Iqela: Iiplesiosauri
Usapho / iclade: Cryptoclididae2
Ukuhlelwa: Plesiosauria > Sauropterygia2
Ubudala bamatye: 165 ukuya ku-143 izigidi zeminyaka (Callovian / Tithonian)2
Izakhiwo zamatye: Oxford Clay, Jagua, Kimmeridge Clay2
Amazwe: iUnited Kingdom, iCuba, i-Argentina, iFransi2
Iirekhodi zeefosili: 17 kwi-Paleobiology Database2
Ikwaziwa ngokuba: Apractocleidus (amagama amadala ngoku abalwa njengesilwanyana esinye)2
Ukufunyanwa: The first fossils were described in 1871 by John Phillips as Plesiosaurus eurymerus. Harry Govier Seeley renamed it Cryptoclidus in 1892.1 2
Kusaxoxwa ngayo: Scientists are not sure whether Cryptoclidus caught prey by swimming fast or by ambushing it, because its skeleton was not built for speed.1
