Illustration of a hypothetical placental mammal ancestor. After studying the DNA of living mammals and the morphology of both living and extinct mammals, scientists believe this animal would have lived 200, 000 to 400, 000 years after the death of the dinosaurs. It would have had a long furry tail, ate insects and weighed between six to 245 grams. | |
