Leninia

Igama lithetha: “named after Vladimir Lenin, because the museum where the fossil is kept is in the Lenin Memorial and Lenin school complex in Ulyanovsk, Russia”1

Leninia was a marine reptile that lived in the Early Cretaceous seas, not a dinosaur. It had huge eyes and probably dove deep to hunt for fish and squid.1

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

izinto ezimnandi

Iinyani ezimnandi

Only part of the skull was found, about 45 centimetres (18 inches) long. Scientists think the whole skull was between 65 and 90 centimetres (26 to 35 inches) long.1

Leninia had one of the largest scleral rings (the bony ring that supports the eye) of any ichthyosaur. Only Baptanodon and the giant Temnodontosaurus had bigger ones.1

Its skull bones form a star-shaped pattern, which is why its species name is stellans, meaning 'shining' or 'star-like'.1

Leninia lived about 119 to 113 million years ago, during the Early Cretaceous Period.1

It is one of the latest-living members of the ophthalmosaurine group, which were deep-diving ichthyosaurs with very large eyes.1

The fossil was discovered in 2012 in a limestone nodule on the banks of the Volga River, near the town of Kriushi.1

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

Kwiingcali zeedayinaso

Igama lenzululwazi: Leninia
Inikwe igama ngu:: Fischer et al. 20133
Iqela: Ii-ichthyosauri
Usapho / iclade: Ophthalmosauridae3
Ukuhlelwa: Ichthyosauria > Ichthyosauromorpha3
Ubudala bamatye: 121 ukuya ku-120 izigidi zeminyaka (Aptian)3
Amazwe: iRashiya3
Iirekhodi zeefosili: 1 kwi-Paleobiology Database3
Ukufunyanwa: Leninia was named in 2013 by Valentin Fischer and colleagues. The only known fossil is a partial skull found in 2012 on the Volga River banks in Russia.1 3
Kusaxoxwa ngayo: Scientists are not sure exactly how long the whole animal was, because only a piece of the skull has been found.1
