Mosasaurus was first discovered in 1766 in a limestone quarry near Maastricht, Netherlands, long before the word 'dinosaur' was even invented.1

The first Mosasaurus skull was seized by the French army in 1795 and is still on display in Paris today.1

Mosasaurus had a special joint in its lower jaw that allowed it to open its mouth extra wide, so it could swallow very large prey.1

Unlike most lizards, Mosasaurus gave birth to live young in the open ocean and did not need to come ashore to lay eggs.1

Some Mosasaurus species were warm-blooded, which helped them live in both cold polar waters and warm tropical seas.1

Mosasaurus teeth were curved and sharp, and they sat in sockets like ours, which helped it bite hard without hurting itself.1

Mosasaurus lived during the Late Cretaceous Period, from about 94 million to 66 million years ago, when a huge sea called the Western Interior Seaway covered parts of North America.1

?Was Mosasaurus a dinosaur?

No, Mosasaurus was not a dinosaur. It was a giant marine reptile and a close relative of modern lizards and snakes.1 2

?How big was Mosasaurus?

The largest species, Mosasaurus hoffmanni, may have reached 17 to 18 metres (56 to 59 ft), though many scientists think 11 to 12 metres (36 to 39 ft) is more likely. Other species were about 8 to 10 metres (26 to 33 ft) long.1 2

?What did Mosasaurus eat?

Mosasaurus was a carnivore that ate fish, sharks, squid, birds, sea turtles, and even other mosasaurs. It could swallow very large prey thanks to a special hinge in its jaw.1 3 2

?When did Mosasaurus live?

Mosasaurus lived during the Late Cretaceous Period, from about 82 to 66 million years ago, when it went extinct along with the dinosaurs.2

?Could Mosasaurus swim fast?

Probably up to about 26 km/h (16 mph) in a short burst, about as fast as a grown-up riding a bike. This is an estimate. Mosasaurus swam by swishing its tail, but it probably could not swim very fast for long.3 4

?Did Mosasaurus have any predators?

Adult Mosasaurus had no natural predators, but young ones were hunted by sharks and giant fish. Mosasaurs also fought and sometimes ate each other.3 2

?Where have Mosasaurus fossils been found?

Mosasaurus fossils have been found in North and South America, Europe, Africa, Western Asia, and Antarctica, showing it lived in oceans all over the world.2

?Was Mosasaurus bigger than T. rex?

Yes, Mosasaurus was longer than T. rex. The largest Mosasaurus species could reach 17 to 18 metres (56 to 59 ft) long, while T. rex was about 12 metres (40 ft) long.1 2

?Did Mosasaurus lay eggs?

No, Mosasaurus gave birth to live young in the open ocean. Scientists found a fossil of a pregnant mosasaur with five babies inside.1 3

?How did Mosasaurus become extinct?

Mosasaurus went extinct about 66 million years ago, at the same time as the dinosaurs, likely because of the asteroid impact that caused a mass extinction.2
