Ancestors of modern capybara: cavy-like rodents (cavimorphs) Late Eocene to Early Oligocene (37.5 to 31.5 million years ago), Chilean Andes. Cavimorphs perhaps arrived in South America from Africa. True capybaras first recorded in Argentina about 9 million years ago. As many as 56 separate fossil species, most described solely on basis of teeth But teeth change shape significantly as a capybara ages. In actuality, not so many species.
