gauza bikainak

Datu dibertigarriak

Liopleurodon had four strong flippers that helped it accelerate quickly to catch prey.1

A study using a swimming robot showed that its four-flipper swimming style gave it great acceleration, perfect for ambushing prey.1

Fossils of Liopleurodon have been found with stomach contents including fish bones, squid hooklets, and even a reptile tooth.1

The BBC show Walking with Dinosaurs made Liopleurodon look 25 metres long, but real fossils show it was much smaller, up to about 8 metres.1

Liopleurodon could probably smell underwater by sniffing through its nostrils to find food.1

The first Liopleurodon fossil was just a single tooth, which makes it hard for scientists to tell different species apart.1

zure galderak

Liopleurodon: gehien egindako galderak

?How big was Liopleurodon?

Liopleurodon reached a maximum length of just over 8 metres (about 26 feet), based on the most complete fossils. Earlier claims of 25 metres were exaggerated.1 2

?Was Liopleurodon a dinosaur?

No, Liopleurodon was a marine reptile called a pliosaur, not a dinosaur. Dinosaurs lived on land.1

?What did Liopleurodon eat?

Liopleurodon ate fish, squid, and other marine reptiles. It was an ambush predator that used its four flippers to accelerate quickly and catch prey.1

?When did Liopleurodon live?

Liopleurodon lived during the Middle and Late Jurassic Period, about 166 to 155 million years ago.1

?Could Liopleurodon swim fast?

Liopleurodon was a powerful swimmer with four paddle-like flippers. A swimming robot study showed its four-flipper style gave it great acceleration, perfect for ambushing prey.1

?How did Liopleurodon get its name?

Liopleurodon means 'smooth-sided tooth' in Greek, because its teeth were smooth on the sides. The species name ferox means 'fierce' in Latin.1

?Where were Liopleurodon fossils found?

Most Liopleurodon fossils come from Europe, especially England and France. One possible fossil was also found in Mexico.1

?Why did Liopleurodon have a big head?

Liopleurodon had an unusually large skull, making up about a quarter of its total body length. This helped it tackle large prey.2

Mito-hauslea

Mitoa: Liopleurodon was a dinosaur.

Egia: Liopleurodon was a plesiosaur, a marine reptile that lived in the sea, not a dinosaur.1
