Mollesaurus

Naam beteken: “lizard from the Los Molles Formation”1

Het geëet: VleisIgtiosourusseMiddel-JuraTegnies nie 'n dinosourus nie

Mollesaurus was a large, fast-swimming marine reptile that lived in the Jurassic seas. It looked a bit like a dolphin but was actually an ichthyosaur, not a dinosaur. With its big eyes and sharp teeth, it was a top hunter in the ocean.1 3

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

Mollesaurus is one of the oldest known ophthalmosaurid ichthyosaurs, living about 171 to 170 million years ago.1

Its name comes from the Los Molles Formation in Argentina, where its fossils were found.1

The only known fossil of Mollesaurus is a partial skeleton including part of the skull and most of the backbone.1

Mollesaurus was a thunnosaur, meaning it had a tuna-like body built for fast swimming.1

Some scientists once thought Mollesaurus was a species of Ophthalmosaurus, but newer studies show it is its own genus.1

Mollesaurus and another ichthyosaur called Chacaicosaurus were found at the same spot in Argentina.1

Vir dino-kenners

Wetenskaplike naam: Mollesaurus
Benoem deur: Fernandez 19993
Groep: Igtiosourusse
Familie / klade: Ophthalmosauridae3
Klassifikasie: Ichthyosauria > Ichthyosauromorpha3
Ouderdom van die rotse: 171 tot 169 miljoen jaar (Bajocian)3
Rotsformasies: Los Molles3

Ontdekking: Mollesaurus was named by paleontologist Marta S. Fernández in 1999 based on a partial skeleton found in the Los Molles Formation of Argentina.1 3
Steeds omstrede: Scientists are not sure exactly how big Mollesaurus grew, because only one partial skeleton has been found.1
