A new study reveals that a sea monster with very sharp teeth and a “saw-like blade” was swimming in what is now Morocco’s waters about 66 million years ago.
Miners found the remains of this creature (a lizard-like marine reptile called Mosasaurus that lived during the dinosaur era) at the Sidi Chennane phosphate mine in Khouribga, Morocco. When researchers examined the specimens, they noticed its distinctive teeth with characteristics never before seen in other known reptiles, living or extinct.
In honor of the predator’s deadly but strange pearly white, the team named it Mosasaurus. Xenodens calminechari, Its genus name means “strange teeth” in Greek and Latin, and its species name means “like a saw” in Arabic.

Gave that dense knife-like tooth X. calminechari It was a shark-like slice bite and may have been the key to its survival. X. calminechari It wasn’t big — it was the size of a porpoise — so it probably relied on its agility and weapon-like teeth.
In the second half Cretaceous, When X. calminechari Alive, Morocco lay under the tropical sea. Their warm water was filled with predatory marine animals such as other Mosasaurus species, long-necked Plesiosauria, giant sea turtles, and Saber-toothed fish.
“A wide variety of Mosasaurus lived here,” said Nick Longrich, a senior researcher at the Milner Evolution Center at the University of Bath in the United Kingdom. Said in a statement.. “Some were huge, deep-sea predators, like modern sperm whales, while others had huge teeth and could grow up to 10 meters. [32 feet] For a long time, the apex predator Orca, Still others ate shellfish like in modern times Sea otter — And there was a strange little thing Xenodens.. “
X. calminechariThe rare dentition of the dentition is likely to have given it a unique hunting strategy that “probably involves cutting movements used to carve and clean fragments from large prey,” researchers say. I am writing in my research.
Nour-Eddine Jalil, a paleontologist and senior researcher at the National Museum of Natural History in Paris and Caddy Eod, said, “Mosasaurus with shark teeth is an amazing novel adaptation of Mosasaurus, from the artist’s imagination. Looked like a fantastic creature. ” A university in Marrakech, Morocco said in a statement.
Discovery X. calminechari There is also additional evidence that Moroccan marine reptile ecosystems and diversity flourished at the end of the Cretaceous. But it was all over when a 6-mile (10 km) wide rock slammed into Earth and these marine life and dinosaurs were extinct.
A pre-copy of the study was published online in the journal on January 16th. Cretaceous study..
