Pachypleurosaurus

Izirhubuluzi zaselwandleiTriassic ephakathiNgokwenene ayisiyo dayinaso

Pachypleurosaurus was a small marine reptile that swam in warm, shallow seas during the Triassic Period. It looked a bit like a modern sea lizard and used its long tail to wriggle through the water.1

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

izinto ezimnandi

Iinyani ezimnandi

It swam by wiggling its body and tail from side to side, like a crocodile or a marine iguana.1

Its hind limbs probably acted as rudders to help steer, while its front limbs were becoming more important for paddling.1

Pachypleurosaurus lived during the Middle Triassic, about 247 to 237 million years ago.4

Fossils of Pachypleurosaurus have been found in the Calcare di Meride formation in Italy and Switzerland.4

Scientists think Pachypleurosaurus is closely related to plesiosaurs, the long-necked marine reptiles that came later.1

Umfanekiso owenziwe yi-AI: Pachypleurosaurus — Umfanekiso owenziwe yi-AI obonisa indlela Pachypleurosaurus 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: Pachypleurosaurus

?How big was Pachypleurosaurus?

About 0.2 to 1 metre (0.66 to 3.28 feet) long, similar to a small lizard.3

?What did Pachypleurosaurus eat?

It ate small fish and crustaceans, using its peg-like teeth to grab them.3

?Could Pachypleurosaurus live on land?

No, its limb bones were too small and weak. It was a fully aquatic reptile that stayed in the water.3

Inikwe igama ngu:: Broili 19274
Iqela: Izirhubuluzi zaselwandle
Usapho / iclade: Pachypleurosauridae4
Ukuhlelwa: Sauropterygia4
Ubudala bamatye: 247 ukuya ku-237 izigidi zeminyaka ()4
Izakhiwo zamatye: Calcare di Meride, Meride, Besano4
Amazwe: iSwitzerland, i-Itali4
Iirekhodi zeefosili: 5 kwi-Paleobiology Database4
Ukufunyanwa: Pachypleurosaurus was named by Broili in 1927 based on fossils from the Middle Triassic of Italy and Switzerland.4
Kusaxoxwa ngayo: Scientists are still debating how many species of Pachypleurosaurus existed, because the fossils show a lot of variation.2
