Argovisaurus

Naam beteken: “Aargau lizard”1

Het geëet: VleisIgtiosourusseMiddel-JuraTegnies nie 'n dinosourus nie

Argovisaurus was a huge, dolphin-like marine reptile that swam in the warm seas of the Middle Jurassic. It was a top predator with a strong snout and sharp teeth, hunting big squid and fish. Even though it looked like a dolphin, it was actually an ichthyosaur, not a dinosaur.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

Argovisaurus lived about 170 to 165 million years ago, during the Middle Jurassic period.3

Its skull was almost 1.2 metres long, making it one of the largest ichthyosaurs of its time.2

The only known fossil was discovered by a private collector named Elmar Meier over twenty years before scientists studied it.2

Argovisaurus had a robust snout and special tooth sockets called pseudoalveoli in the front half of its jaws.2

It is one of the earliest members of the group Ophthalmosauria, which includes many later ichthyosaurs.2

Scientists used CT scans and surface scans to make a 3D reconstruction of its skull.2

The fossil was found in the Hauptrogenstein Formation, which was once a shallow, warm sea.1

KI-prent van Argovisaurus — 'n KI-prent van hoe Argovisaurus 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: Argovisaurus
Benoem deur: Miedema et al. 20243
Groep: Igtiosourusse
Familie / klade: Ophthalmosauridae3
Klassifikasie: Ichthyosauria > Ichthyosauromorpha3
Ouderdom van die rotse: 171 tot 165 miljoen jaar (Bajocian / Bathonian)3
Rotsformasies: Hauptrogenstein3
Lande: Switserland3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: Argovisaurus was named in 2024 by Miedema and colleagues. The only skeleton was found in a quarry in Switzerland by private collector Elmar Meier before 2004, and later acquired by the Paleontological Museum of the University of Zurich.3 2
Steeds omstrede: Scientists are not sure exactly how large Argovisaurus grew, because only one incomplete skeleton has been found.2
