Mosasaur
Mosasaurs (from Latin "Mosa" meaning the 'Meuse river', and Greek σαύρος "sauros" meaning 'lizard') are an extinct group of large marine reptiles containing 38 genera in total. Their first fossil remains were discovered in a limestone quarry at Maastricht on the Meuse in 1764. Mosasaurs probably evolved from an extinct group of aquatic lizards known as aigialosaurs in the Early Cretaceous. 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.
Mistaken Point Ecological Reserve
The first fossil to be found in the area, "Fractofusus misrai", was discovered in June 1967 by Shiva Balak Misra, an Indian graduate student studying geology at Memorial University of Newfoundland. The site became quickly recognized in the mid-1980s as an important find containing probably the oldest metazoan fossils in North America and the most ancient deep-water marine fossils in the world. a A 5 kilometer stretch of coastline was first established provisionally as a reserve by the provincial government in 1984 and was permanently designated in 1987. It was later expanded in 2009 after further fossil discoveries.
