Leninia

Naam beteken: “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

Het geëet: VleisIgtiosourusseVroeë KrytTegnies nie 'n dinosourus nie

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

Prettige feit: hierdie seereptiel het geswem terwyl dinosourusse op land geloop het. Almal noem hulle dino's, maar hulle was 'n ander tak van die reptiele.

Prettige feite

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

KI-prent van Leninia — 'n KI-prent van hoe Leninia dalk gelyk het, deur 'n rekenaar gemaak uit wat wetenskaplikes weet. Dit is 'n raaiskoot: die regte dier het dalk anders gelyk, en niemand weet wat sy regte kleure was nie.

Vir dino-kenners

Wetenskaplike naam: Leninia
Benoem deur: Fischer et al. 20133
Groep: Igtiosourusse
Familie / klade: Ophthalmosauridae3
Klassifikasie: Ichthyosauria > Ichthyosauromorpha3
Ouderdom van die rotse: 121 tot 120 miljoen jaar (Aptian)3
Lande: Rusland3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: 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
Steeds omstrede: Scientists are not sure exactly how long the whole animal was, because only a piece of the skull has been found.1
