In the last million years since the Late Miocene , South America became connected with the continent of North America via the Panama Block that closed the marine Bolivar Trough , leading to the Great American Interchange , the interchange of biota from both continents. [2] The first species discovered to have made the northward migration was Pliometanastes , a fossil ground sloth species, roughly the size of a modern black bear . [2] Several migrations to the Southern Hemisphere were undertaken by tougher, North American mammal carnivores; fewer species migrated in the opposite direction from south to north. The result of the intrusion of North American fauna was that hundreds of South American species became extinct in a relatively short time and that about 60% of present-day South American mammals have evolved from North American species. [3] However, some species were able to adapt and spread into North America. Apart from Pliometanastes , during the Irvingtonian stage of the mammal land stages, around mya , species as Pampatherium , a giant armadillo , ground sloth Megatherium , giant anteater Myrmecophaga , a Neogene capybara ( Hydrochoerus ), Meizonyx , opossum Didelphis , and Mixotoxodon followed the route north. [4] The terror bird Titanis was the only discovered South American carnivore species who made the journey into North America. [5]
