most fossils have been reported from europe, but some are known from africa and greenland. since 2005, the published range extended to mongolia and china. the age of haramiyid fossils range from upper triassic up to late cretaceous. this has important implications: the fact that haramiyids were present in the late triassic supports the idea that crown-group mammals originated at least 208 million years ago, much earlier than some previous research suggests.
