Isfjordosaurus

Naam beteken: “Isfjord lizard, named after the Isfjord area in Svalbard where it was found”1

Het geëet: VleisIgtiosourusseVroeë Trias tot Middel-TriasTegnies nie 'n dinosourus nie

Isfjordosaurus was a small marine reptile that swam in the seas during the Early Triassic, about 248 million years ago. It looked a bit like a dolphin but was not a dinosaur. Its fossils were found on a cold Arctic island called Spitsbergen.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

Isfjordosaurus is known from only a single upper arm bone, called a humerus, which makes it a mysterious animal.2

Some scientists are not sure if Isfjordosaurus was really an ichthyosaur, because the bone looks unusual.2

It lived during the Early Triassic, a time when ichthyosaurs were just starting to appear in the oceans.1

The name Isfjordosaurus comes from the Isfjord, a large fjord on Spitsbergen, where the fossil was found.1

The only known species is called Isfjordosaurus minor, and 'minor' means smaller, hinting it was a small reptile.1

KI-prent van Isfjordosaurus — 'n KI-prent van hoe Isfjordosaurus 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 Isfjordosaurus was a dinosaur because it lived in the sea and had 'saurus' in its name.

Waarheid: Isfjordosaurus was an ichthyosaur, a marine reptile, not a dinosaur. Dinosaurs lived on land.1

Wetenskaplike naam: Isfjordosaurus
Benoem deur: Motani 19993
Groep: Igtiosourusse
Familie / klade: Ichthyosauria3
Klassifikasie: Ichthyosauria > Ichthyosauromorpha3
Ouderdom van die rotse: 249 tot 247 miljoen jaar ()3
Rotsformasies: Vikinghøgda3

Ontdekking: The fossil was first described by Carl Wiman in 1910, but the name Isfjordosaurus was given later by Ryosuke Motani in 1999.1 3
Steeds omstrede: Scientists still debate whether Isfjordosaurus was truly an ichthyosaur, because the only known bone is so unusual.2
