Hello! Sorry for my idleness. I have been very busy with projects. As you may expect, I am also looking forward to Jurassic World. Today starts Mosasaur Week. What exactly is a mosasaur. If you are a die-hard dinosaur fan or rock collector, you may be familiar with them. Mosasaurs to start, were a type of marine reptile from the Late Cretaceous Period. Mosasaurs are named because the first specimen to be described was found in a quarry near the Meuse River in the Netherlands. So "mosa" meaning Meuse and "sauros" meaning lizard translate to Meuse River Lizard. Mosasaurs did not just live in Europe, they have also been found in Africa, Turkey, Japan, Russia, New Zealand, and Canada, but most commonly in the Midwestern United States. Mosasaurs evolved from land-living monitor lizards like the Komodo dragon that fled to the sea, to escape the mighty dinosaurs. As soon as they became adapted to the water, they grew very large. Some were almost 60 feet long! Mosasaurs, like the snakes of today, had double hinged jaws. This meant that they could have swallowed their prey in one bite! Although large sharks fed on mosasaur young, it was usually the other way around with the adults. The battles weren't always that clean. Teeth from sharks such as
Squalicorax and
Cretoxyrhina have been found in the bones of large mosasaurs. Mosasaurs became extinct about 66 million years ago, along with the dinosaurs and flying reptiles
