Xenodens
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

Xenodens means 'strange tooth' in Greek and Latin, and its species name calminechari means 'like a saw' in Arabic.1
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
Xenodens lived about 72 to 66 million years ago, near the end of the Age of Dinosaurs.2
Scientists first described Xenodens in 2021 from two upper jaw bones found in a phosphate mine in Morocco.1
Some scientists thought the fossil might be a fake, but CT scans in 2025 showed the teeth were real and naturally attached.1
Xenodens was small for a mosasaur, only about 1 meter (3.3 feet) long. Many other mosasaurs were much bigger.1
