Opallionectes

Igama lithetha: “opal swimmer from Andamooka”1

Yayitya: InyamaIiplesiosauriiCretaceous yokuqalaNgokwenene ayisiyo dayinaso

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

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

izinto ezimnandi

Iinyani ezimnandi

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

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

Kwiingcali zeedayinaso

Igama lenzululwazi: Opallionectes
Inikwe igama ngu:: Kear 20063
Iqela: Iiplesiosauri
Usapho / iclade: Plesiosauroidea3
Ukuhlelwa: Plesiosauria > Sauropterygia3
Ubudala bamatye: 120 ukuya ku-113 izigidi zeminyaka (Aptian)3
Izakhiwo zamatye: Bulldog Shale3
Amazwe: i-Ostreliya3
Iirekhodi zeefosili: 1 kwi-Paleobiology Database3
Ukufunyanwa: 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
Kusaxoxwa ngayo: 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
