Reassessment and reassignment of the early Maastrichtian mosasaur Hainosaurus bernardi Dollo, 1885, to Tylosaurus Marsh, 1872
Redescription of Hainosaurus bernardi Dollo, 1885a, from the early Maastrichtian of the Ciply Phosphatic Chalk of Belgium, results in a reassignment of the taxon to the genus Tylosaurus Marsh, 1872, because the genus Hainosaurus cannot be diagnosed independent of Tylosaurus . The diagnosis of Hainos...
