Xenodens was a mosasaur, a giant marine lizard that lived in the sea during the time of dinosaurs. It had a mouth full of flat, blade-like teeth that worked like a saw, just like a shark or a piranha. This helped it slice through fish, squid, and even other sea creatures.1

1

Xenodens means 'strange tooth' in Greek and Latin, and its species name calminechari means 'like a saw' in Arabic.1

2

Its teeth were short, flattened, and blade-like, forming a saw-like edge along the jaw. No other land or sea reptile had teeth like this.1

3

Xenodens lived about 72 to 66 million years ago, near the end of the Age of Dinosaurs.2

4

Scientists first described Xenodens in 2021 from two upper jaw bones found in a phosphate mine in Morocco.1

5

Some scientists thought the fossil might be a fake, but CT scans in 2025 showed the teeth were real and naturally attached.1

6

Xenodens was small for a mosasaur, only about 1 meter (3.3 feet) long. Many other mosasaurs were much bigger.1

?Was Xenodens a dinosaur?

No, Xenodens was a mosasaur, a marine lizard that lived in the sea during the time of dinosaurs.1

?How big was Xenodens?

About 1 meter (3.3 feet) long, which is small for a mosasaur.1

?What did Xenodens eat?

It likely ate fish, squid, crustaceans, and scavenged dead marine reptiles, using its saw-like teeth to slice through food.1

?Why did Xenodens have strange teeth?

Its short, flattened, blade-like teeth formed a saw-like edge, similar to dogfish sharks and piranhas, for cutting prey.1

Mothubi wa ditlhamane

Tlhamane: Xenodens was a dinosaur.

Boammaaruri: Xenodens was a mosasaur, a type of marine lizard that lived in the ocean. Mosasaurs are not dinosaurs.1

Xenodens was named in 2021 by Nick Longrich and colleagues based on a left upper jaw bone bought from a local farmer in Morocco. The fossil came from the Sidi Chennane phosphate mine.1

Some scientists still debate whether Xenodens is a real species or a fake fossil, though CT scans support its authenticity.1
