Merriamosaurus

Naam beteken: “Merriam's lizard”1

Merriamosaurus was an ancient marine reptile that swam in the seas around what is now Svalbard, Norway, about 248 million years ago. It was a type of ichthyosaur, a dolphin-like reptile that breathed air but lived in the water. Merriamosaurus was a top predator, hunting 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

Merriamosaurus was named in 2002 by scientists Maisch and Matzke.1

It lived during the Spathian stage of the Early Triassic, about 248 to 247 million years ago.1

Merriamosaurus was a basal longipinnate ichthyosaur, meaning it had long flippers and was an early relative of more advanced ichthyosaurs.2

It was the most derived of the Lower Triassic ichthyosaurs known at the time of its description.2

Merriamosaurus gave birth to live young, like many other ichthyosaurs.1

Its fossils were found in the Sticky Keep Formation on Spitsbergen.1 2

KI-prent van Merriamosaurus — 'n KI-prent van hoe Merriamosaurus 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: Merriamosaurus
Benoem deur: Maisch and Matzke 20023
Groep: Igtiosourusse
Familie / klade: Merriamosauridae3
Klassifikasie: Ichthyosauria > Ichthyosauromorpha3
Ouderdom van die rotse: 249 tot 247 miljoen jaar ()3
Rotsformasies: Sticky Keep3
Lande: Svalbard3
Fossielrekords: 1 in The Paleobiology Database3
Ontdekking: Merriamosaurus was first described from isolated bones, but later more complete skeletons were found in the Sticky Keep Formation of Spitsbergen. It was named by Michael W. Maisch and Andreas T. Matzke in 2002.1 2
Steeds omstrede: Scientists are not sure about the exact size of Merriamosaurus because only partial skeletons have been found.2
