Callawayia

Igama lithetha: “named after ichthyosaur researcher Jack Callaway”1

Yayitya: InyamaIi-ichthyosauriiTriassic yamvaNgokwenene ayisiyo dayinaso

Callawayia was a small, fast-swimming marine reptile that lived in the Late Triassic oceans. It looked a bit like a dolphin but was actually an ichthyosaur, not a dinosaur.1 2

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

izinto ezimnandi

Iinyani ezimnandi

Callawayia had more than 54 vertebrae in front of its hips, giving it a long, flexible body.1

Its front flippers had four digits, but its back flippers only had three.1

The first two neck vertebrae of Callawayia were not fused together, unlike in some other ichthyosaurs.1

A tiny bone called a pisiform was present in each foreflipper, which is unusual for ichthyosaurs.1

The humerus (upper arm bone) was short and wide with a notched front edge.1

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

Inyaniso ngeentsomi

Intsomi: Callawayia is sometimes called a dinosaur.

Inyaniso: Callawayia was an ichthyosaur, a marine reptile that lived in the ocean, not a dinosaur. Dinosaurs lived on land.1

Ukufunyanwa: The first fossil was found in 1987 on the shore of Williston Lake in British Columbia, Canada. It was named Callawayia in 2000 by Michael Maisch and Andreas Matzke.1
Kusaxoxwa ngayo: Scientists still debate whether a species from China called 'Callawayia wolonggangense' really belongs to the same genus.1
