Liodon anceps species,
Late Cretaceous period, Morocco,
100- 66 Million Years Old.
Mosasaur was a marine dinosaur of the Late Cretaceous. They were similar in many ways to a modern dolphin, breathing air and giving birth to live young; however, they were mostly much larger – 4m to 13m, species dependant. With peglike teeth, their diet was obviously seafood, and ammonite fossil shells have been found neatly punched with their teethmarks, indicating the squid-like ammonite was on the diet also.
The Mosasaur was a large marine reptile, air breathing & used its tail for propulsion. They probably relied on ambush predation, much like a crocodile, and they are known to have eaten ammonites - the shells of which sometimes show the distinct line of a Mosasaur's teeth puncturing through as the result of a savage bite. They were the dominant predator of the Cretacious seas.
