Meyerasaurus

Het geëet: VleisPlesiosourusseVroeë JuraTegnies nie 'n dinosourus nie

Meyerasaurus was a fierce marine reptile that swam in the seas during the time of the dinosaurs. It was not a dinosaur, but a plesiosaur with a big head and strong jaws. It hunted fish and other sea creatures.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

Meyerasaurus was about 3.35 metres long, with a skull that was only 37 centimetres long. That means its head was quite small compared to its body.2

It had a short and wide snout, and its humerus (upper arm bone) was curved and longer than its femur (thigh bone).2

Meyerasaurus lived about 184 to 183 million years ago, during the Early Jurassic period.1

The only known fossil of Meyerasaurus was damaged during a bombing raid on Stuttgart in 1944, but it was rescued and repaired.2

Meyerasaurus belongs to a group called Rhomaleosauridae, which were plesiosaurs with short necks and big heads.2

Its teeth had fine ridges on them, called lingual striations, which helped it grip slippery prey.2

KI-prent van Meyerasaurus — 'n KI-prent van hoe Meyerasaurus 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.

Mite-breker

Mite: Some people think Meyerasaurus was a dinosaur because it lived during the age of dinosaurs.

Waarheid: Meyerasaurus was a marine reptile, not a dinosaur. Dinosaurs lived on land and had different body features.2

Vir dino-kenners

Wetenskaplike naam: Meyerasaurus
Benoem deur: Smith and Vincent 20103
Groep: Plesiosourusse
Familie / klade: Rhomaleosauridae3
Klassifikasie: Plesiosauria > Sauropterygia3
Ouderdom van die rotse: 184 tot 183 miljoen jaar (Toarcian)3
Rotsformasies: Posidonia Shale3
Lande: Duitsland3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: The fossil was first described by Eberhard Fraas in 1910, but it was given its own genus name Meyerasaurus by Smith and Vincent in 2010. The specimen was found in Holzmaden, Germany.2 1
Steeds omstrede: Scientists are still debating whether Rhomaleosauridae is a separate family, because different studies give different results.2
