When was the first mosasaurus discovered?

The Mosasaurus hoffmannii skull found near Maastricht around 1770. were first discovered in 1764, near the Meuse River, which inspired the name “mosasaur”. The fossil skull was discovered in the Netherlands at a limestone quarry near the city, Maastricht.

What killed the mosasaurus?

During the last 20 million years of the Cretaceous period (Turonian–Maastrichtian ages), with the extinction of the ichthyosaurs and pliosaurs, mosasaurs became the dominant marine predators. They became extinct as a result of the K-Pg event at the end of the Cretaceous period, about 66 million years ago.
