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

Mfundo yosangalatsa: chokwawa cha m'nyanja ichi chinkasambira pamene madainoso ankayenda pamtunda. Aliyense amazitcha madino, koma zinali nthambi ina ya zokwawa.

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

Chithunzi cha Opallionectes chopangidwa ndi AI — Chithunzi cha momwe Opallionectes mwina ankaonekera, chopangidwa ndi kompyuta kuchokera pa zomwe asayansi amadziwa. Ndi kungoyerekeza: nyama yeniyeniyo mwina inkaoneka mosiyana, ndipo palibe amene akudziwa mitundu yake yeniyeni.

Kupezeka: The species Opallionectes andamookaensis was named by Benjamin P. Kear in 2006, based on a partial opalized skeleton found in an opal mine at Andamooka, South Australia.1 3
Akukambiranabe: Scientists are not sure exactly how Opallionectes adapted to the cold waters it lived in, whether by migrating or by having a higher body temperature.1

Mfundo iliyonse patsamba lino ili ndi nambala yosonyeza kumene yachokera. Ngati talakwitsa kanthu, pepa, ndife okonda madino, osati magazini ya sayansi. Tiuze pa [email protected] ndipo tikonza.

Rex ali ndi njala! Dino Wiki ndi ntchito ya bambo kwa mwana wawo wamwamuna wokonda madainoso, yaulere popanda zotsatsa ndi zokazonda. Akuluakulu angadyetse Rex zokhwasula-khwasula kuti tsambali lipitirize kupezeka pa intaneti.Dyetsa Rex
