Naam beteken: “wing fin”1

Arthropterygius was a large, fish-shaped marine reptile that swam in the oceans during the late Jurassic period. It had a long snout and strong flippers, and it was a fast hunter of fish and squid.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

Arthropterygius had a special opening for the internal carotid artery on the back of its braincase, a feature unique among ichthyosaurs.2

Fossils of Arthropterygius have been found in both the Northern and Southern Hemispheres, showing it lived in warm and cold seas.1 2

One specimen from Svalbard, Norway, was about 3.8 to 4.3 metres (12 to 14 feet) long and was probably an adult.1

The name Arthropterygius means 'wing fin', referring to the shape of its flippers.1

Arthropterygius lived in shallow seas with methane seeps, where the seafloor was about 150 metres (490 feet) deep and had little oxygen.1

It belonged to a group called ophthalmosaurids, which were the last surviving ichthyosaurs before they went extinct.1

It was a fast hunter of fish and squid, using its long snout and strong flippers to catch prey.1

?Was Arthropterygius a dinosaur?

No, Arthropterygius was an ichthyosaur, a type of marine reptile that lived in the oceans, not a dinosaur.1

Vir dino-kenners

Wetenskaplike naam: Arthropterygius
Benoem deur: Maxwell 20103
Groep: Igtiosourusse
Familie / klade: Ophthalmosauridae3
Klassifikasie: Ichthyosauria > Ichthyosauromorpha3
Ouderdom van die rotse: 162 tot 143 miljoen jaar (Oxfordian / Tithonian)3
Rotsformasies: Ringnes, Agardhfjellet, Vaca Muerta3
Lande: Kanada, Noorweë, Argentinië, Rusland3

Ontdekking: The first fossils of Arthropterygius were found on Melville Island, Canada, and were originally named Ophthalmosaurus chrisorum in 1993. In 2010, scientist Erin Maxwell gave them a new genus name, Arthropterygius.1 3
Steeds omstrede: Scientists are not sure if Arthropterygius lived into the earliest Cretaceous period, or if it went extinct at the end of the Jurassic.1
