Portunatasaurus

Igama lithetha: “Dugi Otok lizard”1

Yayitya: InyamaIimosasauriiCretaceous yamvaNgokwenene ayisiyo dayinaso

Portunatasaurus was a small marine lizard that swam in warm seas during the time of the dinosaurs. It was only about 1 meter long, as long as a big skateboard, and had a long body and special flipper-like arms.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

Portunatasaurus had 10 small bones in its wrist, like land lizards, but also a flattened first finger bone like later sea lizards.2

Its arm was a mix between a walking leg and a swimming paddle, showing how lizards slowly turned into sea swimmers.2

The only skeleton found was almost complete from the neck to the hips, with a perfectly preserved right arm.2

It lived about 100 to 90 million years ago, during the Cenomanian and Turonian ages of the Late Cretaceous.3

Portunatasaurus is the third and youngest aigialosaur (a type of early marine lizard) found in Croatia.2

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

ubuzile

Eyona mibuzo ibuzwa kakhulu: Portunatasaurus

?Is Portunatasaurus a dinosaur?

No, it is a mosasauroid marine lizard, not a dinosaur.1

?How big was Portunatasaurus?

About 1 meter (3.3 feet) long, as long as a big skateboard.1

?What did Portunatasaurus eat?

Scientists do not know for sure, but its jaws were not found, so it is unknown what it ate.2

?Where was Portunatasaurus found?

It was found on the island of Dugi Otok in Croatia.1 4

Kwiingcali zeedayinaso

Igama lenzululwazi: Portunatasaurus
Inikwe igama ngu:: Campbell Mekarski et al. 20194
Iqela: Iimosasauri
Usapho / iclade: Mosasauroidea4
Ukuhlelwa: Mosasauroidea4
Ubudala bamatye: 100 ukuya ku-90 izigidi zeminyaka (Cenomanian / Turonian)4
Amazwe: iCroatia4
Iirekhodi zeefosili: 1 kwi-Paleobiology Database4
Ukufunyanwa: The skeleton was found in 2008 on the island of Dugi Otok in Croatia. Scientists Michelle Mekarski, Dražen Japundžić, Katarina Krizmanić and Michael Caldwell named it Portunatasaurus krambergeri in 2019.1 2
Kusaxoxwa ngayo: Scientists are still debating whether its paddle-like arm evolved earlier in mosasaur history or evolved more than once.2
