Secernosaurus
''Secernosaurus'' (meaning "severed lizard") is a genus of herbivorous dinosaur. ''Secernosaurus'' was a hadrosaur, a "duck-billed" dinosaur which lived during the Late Cretaceous. Its fossils have been found in Argentina.
Its name comes from the fact that it lived in South America, which during the Mesozoic Era was part of the southern supercontinent of Gondwana. Most other hadrosaurs lived in the northern supercontinent of Laurasia, so it was separated from its relatives.
The type species is ''Secernosaurus koerneri'', described in 1979. A species named in 1984, ''Kritosaurus australis'', is thought to be synonymous.
