Ophthalmosaurus

Igama lithetha: “eye lizard”1

Yayitya: InyamaIi-ichthyosauriiJurassic yokuqala ukuya ku-iCretaceous yokuqalaNgokwenene ayisiyo dayinaso

Ophthalmosaurus was a sleek, fast-swimming marine reptile with enormous eyes, almost as big as dinner plates. It lived in the warm seas of the Jurassic period and hunted small fish and squid. Even though it looked like a dolphin, it was actually an ichthyosaur, not a dinosaur.1

Inyani emnandi: esi sirhubuluzi saselwandle sasiqubha ngelixa iidayinaso zazihamba emhlabeni. Wonke umntu uzibiza ngokuba ziidayinaso, kodwa zazilisebe elahlukileyo lezirhubuluzi.

izinto ezimnandi

Iinyani ezimnandi

Ophthalmosaurus had eyes that measured about 22 to 23 centimetres (8.7 to 9.1 inches) across, which is bigger than a human head.1

It could dive to depths of 600 metres (2,000 feet) or more, reaching the twilight zone of the ocean, and stay underwater for about 20 minutes.1

Its tail ended in a two-lobed fin, with the lower half supported by the backbone and the upper half made only of soft tissue, helping it swim fast.1

Ophthalmosaurus had short, rounded limbs, with the front ones bigger than the back ones, which it used for steering rather than paddling.1

Fossils show it lived in shallow seas, like the Oxford Clay in England, which was only about 50 metres (160 feet) deep at the time.1

Some scientists think Ophthalmosaurus could swim at about 2 metres per second (6.6 feet per second) when chasing prey.1

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

Inyaniso ngeentsomi

Intsomi: Ophthalmosaurus was a dinosaur that lived in the water.

Inyaniso: Ophthalmosaurus was an ichthyosaur, a marine reptile, not a dinosaur. Ichthyosaurs were a different group of reptiles that lived in the oceans.1

Kwiingcali zeedayinaso

Igama lenzululwazi: Ophthalmosaurus
Inikwe igama ngu:: Seeley 18742
Iqela: Ii-ichthyosauri
Usapho / iclade: Ophthalmosauridae2
Ukuhlelwa: Ichthyosauria > Ichthyosauromorpha2
Ubudala bamatye: 201 ukuya ku-133 izigidi zeminyaka (Hettangian / Valanginian)2
Izakhiwo zamatye: Oxford Clay, Sundance, Vaca Muerta2
Amazwe: iUnited Kingdom, i-Argentina, iUSA, iRashiya, iFransi, iGreenland2
Iirekhodi zeefosili: 27 kwi-Paleobiology Database2
Ikwaziwa ngokuba: Ancanamunia, Yasykovia (amagama amadala ngoku abalwa njengesilwanyana esinye)2
Ukufunyanwa: Ophthalmosaurus was first described by Harry Seeley in 1874, based on fossils from the Oxford Clay in England. He focused on the shape of the collarbone bones.1 2
Kusaxoxwa ngayo: Scientists still debate whether some species, like Ophthalmosaurus natans from North America, are really separate species or just close relatives.1
