Finally, some meaty questions! Alligators and crocodiles seem to have split
from each other about 100 to 80 million years ago. This is corroborated by
both palaeontological and biochemical studies. The earliest fossil
alligators are from North America and have subsequently appeared in Europe,
Asia and South America. Do you want some references?
