Mosasaurs (from Latin ''Mosa'' meaning the 'Meuse', and Greek ' 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. They belong to the order Squamata, which includes lizards and snakes. Mosasaurs probably evolved from an extinct group of aquatic lizards known as aigialosaurs in the Earliest Late Cretaceous with 42 described genera. 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 themselves became extinct as a result of the K-Pg event at the end of the Cretaceous period, about 66 million years ago. Description Mosasaurs breathed air, were powerful swimmers, and were well-adapted to living in the warm, shallow inland seas prevalent during the Late Cretaceous period. Mosasaurs were so we ...

Haasiasaurus
''Haasiasaurus'' is an extinct genus of early mosasaur, originally named "''Haasia''" by M. J. Polcyn ''et al.'', in honour of the palaeontologist Georg Haas (paleontologist), Georg Haas. (The original name was a junior homonym of ''Haasia'' Bollman, 1893, a genus of millipedes.) ''Haasiasaurus'' was the largest cenomanian mosasaur at . The genus contains the species ''Haasiasaurus gittelmani'', which was found in the Cenomanian 100 million years ago (Upper Cretaceous) rocks near Ein Yabrud, in the Palestinian territories, Palestinian West Bank, approximately north of Jerusalem.
