Secernosaurus
Secernosaurus koerneri
Secernosaurus (meaning "severed lizard") is a genus of herbivorous hadrosaurid dinosaur that lived during the Late Cretaceous of what is now Argentina. This genus and its close relatives lived in South America, unlike most hadrosaurids, which lived in the Laurasian continents of Eurasia and North America. It has been suggested that the ancestors of Secernosaurus crossed into South America when a land bridge temporarily formed between North and South America during the Late Cretaceous and allowed biotic interchange between the two continents.
