Opallionectes was a plesiosaur, a long-necked marine reptile that swam in the seas near Australia. It had needle-sharp teeth and ate fish and squid. Its bones were turned into opal, a shiny gemstone!1

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

Opallionectes lived about 115 million years ago in a cold, possibly freezing sea.1

Its skeleton was found in an opal mine and parts of it turned into opal, a precious gemstone.1

It had fine, needle-like teeth that were flattened side to side, similar to ancient nothosaurs.1

Opallionectes is considered a missing link between older plesiosaurs from 165 million years ago and those from 66 million years ago.1

Scientists think it might have migrated to warmer waters or had a high metabolism to survive the cold.1

Ishusho ya Opallionectes yakozwe na AI — Ishusho yakozwe na AI yerekana uko Opallionectes 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.
