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

Khinjaria's name comes from an Arabic word for dagger, because of its sharp, blade-like teeth.1

Its skull bones were tightly fused together, making its bite very powerful.1

Khinjaria lived at the very end of the Age of Dinosaurs, about 72 to 66 million years ago.4

It was about 8 metres (26 feet) long, as long as a big bus.1

Khinjaria is related to other African mosasaurs like Goronyosaurus and Gavialimimus.1 2

Scientists think Khinjaria was an apex predator, meaning it was at the top of the food chain in its ocean.2
