Mosasaurs

The Mosasaurus is a long extinct genus from the family of Mosasauridae. They were marine living reptile carnivores who lived in the early Cretacious sea around 130 million years ago. They became extinct in the KT-event 65 million years ago.

Meaning of Name:
The name means "Meuse lizard". From Latin Mosa mean 'Meuse River', named from the place in which it was first found, and from Greek Saurus mean Lizard.

Size:
From the fossil records they were measured to a length of 15 meters (49 feet), which is a little bit longer than a bus, they were one of the biggest animals living in the sea at its time. Animals from the same period that could rival it in size were the Plesiosaurs from the order Plesiosauria, or the land living Tyrannosaurus Rex, who also lived in the same period, who both lived to be around 15 to 16 meters (49 to 52 feet) in length. All were extinct in the KT-Event 65 million years ago.
