Mosasaur extinction
Mosasaurs (from Latin Mosa meaning the 'Meuse', and Greek σαύρος sauros meaning 'lizard') comprise a group of extinct, large marine reptiles from the Late Cretaceous. Their first fossil remains were discovered in a limestone quarry at Maastricht on the Meuse in 1764.The heating and cooling of the earth, changes in sea level, asteroids, acid rain and diseases can all be natural factors that cause a species to become extinct. Humans can also be the cause of extinction for certain species.
