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.
Moreae
Few fossils can be definitively assigned to the Moreae. Fruits from the upper Eocene, Miocene and Tertiary have been assigned to "Broussonetia", and fruit matching modern "Morus" have been found in the early Eocene. Based on rates of molecular evolution in chloroplast and nuclear genes, the Moreae s.s. is estimated to be about 59–79 million years old. Nyree Zerega and colleagues proposed a Laurasian origin for the Moreae s.s., with three separate colonisations of South America (by "Sorocea", "Bagassa" and "Trophis") and a later colonisation of Africa by "Milicia".
