Ancient tooth suggests third kind of monkey made trip from Africa to South America millions of years ago

A team of paleontologists with members from France, Brazil and Argentina has found evidence of a third type of monkey crossing the Atlantic Ocean millions of years ago, making the trip from Africa to South America. In their paper published in Proceedings of the National Academy of Sciences, the group describes a tooth they found embedded in rock along the Juruá River in Amazonian, Brazil, and their theories about where its former owner might fit in the animal kingdom.
