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.21

Inyani emnandi: esi sirhubuluzi saselwandle sasiqubha ngelixa iidayinaso zazihamba emhlabeni. Wonke umntu uzibiza ngokuba ziidayinaso, kodwa zazilisebe elahlukileyo lezirhubuluzi.

izinto ezimnandi

Iinyani ezimnandi

1

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

2

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

3

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

4

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

5

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

6

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

7

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

Yenziwe yi-AIUmfanekiso owenziwe yi-AI: Dearcmhara
Umfanekiso owenziwe yi-AI obonisa indlela Dearcmhara esenokuba wayekhangeleka ngayo, wenziwe yikhompyutha ngokwento eyaziwa zizazinzulu. Kukuqikelela nje: esona silwanyana sinokuba sasikhangeleka ngenye indlela, kwaye akukho mntu waziyo imibala yaso yokwenyani.

Ukufunyanwa
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
Kusaxoxwa ngayo
Scientists are not sure exactly how big Dearcmhara was, because only a few bones have been found.1
