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

Akantu gashimishije: iki gikururanda cyo mu nyanja cyogaga mu gihe dinozore zagendaga ku butaka. Bose bakita dinozore, ariko cyari mu rindi shami ry'ibikururanda.

Utuntu dushimishije

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

Ishusho ya Callawayia yakozwe na AI — Ishusho yakozwe na AI yerekana uko Callawayia ishobora kuba yari isa, yakozwe na mudasobwa hashingiwe ku byo abahanga bazi. Ni ugukeka gusa: inyamaswa nyayo ishobora kuba yari isa ukundi, kandi nta muntu uzi amabara yayo nyayo.

Gusenya ibinyoma

Ibivugwa: Callawayia is sometimes called a dinosaur.

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

Rex arashonje! Dino Wiki ni umushinga wa papa umwe yakoreye umuhungu we ukunda dinozore, ni ubuntu, nta matangazo kandi nta bigukurikirana. Abantu bakuru bashobora guha Rex akantu ko kurya kugira ngo Dino Wiki ikomeze kuboneka kuri interineti.Gaburira Rex
