Wahlisaurus

Naam beteken: “Wahl's lizard”1

Het geëet: VleisIgtiosourusseVroeë JuraTegnies nie 'n dinosourus nie

Wahlisaurus was a dolphin-like marine reptile that swam in the seas of Early Jurassic England. It had a very long, slender snout and an overbite, like a swordfish. It was not a dinosaur, but a type of ichthyosaur.1 2

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

Wahlisaurus had a very unusual shoulder bone called a coracoid, which had a large hole in it. This hole is rarely seen in ichthyosaurs.2

The first Wahlisaurus fossil was discovered by a man named Percy Faulkes, who donated it to a museum when he died in 1951.1

Wahlisaurus is named after two scientists: William Wahl and Judy Massare, who both studied ancient marine reptiles.1

Only two specimens of Wahlisaurus have ever been found. The second one was discovered in 1996 but not identified until 2018.1

Wahlisaurus lived during the Hettangian age, about 201 to 199 million years ago, right after a big extinction event.3

Its snout was extremely slender and delicate, and its lower jaw was shorter than its upper jaw, giving it an overbite.2

KI-prent van Wahlisaurus — 'n KI-prent van hoe Wahlisaurus 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: Wahlisaurus
Benoem deur: Lomax 20173
Groep: Igtiosourusse
Familie / klade: Leptonectidae3
Klassifikasie: Ichthyosauria > Ichthyosauromorpha3
Ouderdom van die rotse: 201 tot 200 miljoen jaar (Hettangian)3
Rotsformasies: Scunthorpe Mudstone3
Lande: Verenigde Koninkryk3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: Wahlisaurus was named and described by paleontologist Dean Lomax in 2016. The first fossil, a partial skull and skeleton, was found in Nottinghamshire, England, and had been sitting in a museum collection since 1951.1 2
Steeds omstrede: Scientists are not sure exactly how big Wahlisaurus grew, because only incomplete skeletons have been found.1
