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

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