 Most of the species that became extinct were cold-blooded species and Rancholabrean megafauna, including "Columbian mammoth", "Dire wolf", and "Camelops".Survivors of the Younger Dryas included nocturnal, low-birthrate species residing in the mountainous or forest-like terrains of the Americas, Eurasia, Australia, and Madagascar.The largest, slow-breeding, diurnal species that lived in more open spaces survived in the lower parts of Africa.
