吃：肉魚龍類侏羅紀晚期到白堊紀晚期嚴格來說不是恐龍

Platypterygius was a giant marine reptile that swam in the seas during the time of the dinosaurs. It looked a bit like a dolphin but had a long snout full of sharp teeth. It was a fast hunter that ate fish, sea turtles, and even baby birds.1

趣味小知識：這種海生爬蟲類在海裡游泳的時候，恐龍正在陸地上走路。大家都叫牠們恐龍，但牠們其實是爬蟲類的另一個分支。

趣味知識

Platypterygius means 'flat fin' because its flippers were wide and flat, like paddles.1

It lived from about 161 to 94 million years ago, during the Jurassic and Cretaceous periods.3

Fossils of Platypterygius have been found on every continent except Antarctica.3

Some Platypterygius fossils have baby sea turtles and bird bones in their stomachs, showing what it ate.1

Scientists think Platypterygius was a fast swimmer that chased prey in the open ocean.3

The name Platypterygius has been used for many different ichthyosaurs, and some scientists think it might include several different species.1

關於 Platypterygius 最常被問的問題

?How big was Platypterygius?

Different species reached different sizes. Platypterygius platydactylus was about 5 metres (16 ft) long, while Platypterygius australis was about 7 metres (23 ft) long.1

?What did Platypterygius eat?

It was a large predator that ate fish, squid, and other marine animals. One fossil even had baby sea turtles and bird bones in its stomach.1 2

?Is Platypterygius a dinosaur?

No, it is not a dinosaur. It is an ichthyosaur, a marine reptile that lived in the sea at the same time as dinosaurs.1 2

?When did Platypterygius live?

Platypterygius lived during the Cretaceous period, from about 141 million years ago to 65 million years ago.2

?Could Platypterygius swim fast?

Probably up to about 41 km/h (25 mph), faster than a fast human runner. This is an estimate from its size. Its dolphin-like body and flat flippers helped it chase prey in the open ocean.1 2

?Where were Platypterygius fossils found?

Fossils have been found on many continents, including Australia, Europe, North America, and South America. In Australia, they were found in areas once covered by the Eromanga Sea.1 2
