Dearcmhara

Naam beteken: “marine lizard”1

Het geëet: VleisIgtiosourusseVroeë Jura tot Middel-JuraTegnies nie 'n dinosourus nie

Dearcmhara was a marine reptile that lived in the warm seas around Scotland during the Jurassic Period. It looked a bit like a dolphin with a long snout and flippers, and it was a fast swimmer that hunted fish and squid.2 1

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

Dearcmhara is known from only a few bones: a humerus (upper arm bone) and three vertebrae (back bones).1

Its name comes from Scottish Gaelic and means 'marine lizard'.1

Dearcmhara lived about 184 to 169 million years ago, during the Early to Middle Jurassic.2

It was a basal neoichthyosaurian, meaning it was an early relative of later ichthyosaurs like Ophthalmosaurus.1

The fossils were collected by a man named Brian Shawcross in 1959, and he donated them to a museum instead of keeping them.1

Dearcmhara is one of the first ichthyosaurs from Scotland to be described in detail by scientists.1

Its humerus has a unique deep concavity and a large triangular process that help scientists tell it apart from other ichthyosaurs.1

KI-prent van Dearcmhara — 'n KI-prent van hoe Dearcmhara 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: Dearcmhara
Benoem deur: Brusatte et al. 20155
Groep: Igtiosourusse
Familie / klade: Neoichthyosauria5
Klassifikasie: Ichthyosauria > Ichthyosauromorpha5
Ouderdom van die rotse: 184 tot 169 miljoen jaar (Toarcian / Bajocian)5
Rotsformasies: Bearreraig Sandstone5
Lande: Verenigde Koninkryk5
Fossielrekords: 1 in The Paleobiology Database5
Ontdekking: Dearcmhara was named in 2015 by a team led by Stephen Brusatte. The fossils were found by Brian Shawcross in 1959 on the Isle of Skye, Scotland, and later donated to the Hunterian Museum in Glasgow.1
Steeds omstrede: Scientists are not sure exactly how big Dearcmhara was, because only a few bones have been found.1
