The tooth was then analyzed scientifically and found to be of the earliest mammal. Describe the fossil. The fossil was of a tooth, which was so small in size that on further research showed it to be of an insect-eating mammal. The d
ating process of the fossil showed it to have existed about 160 million years ago. This coincided with when the dinosaurs existed, and so the mammal must have been a night hunter that fed on insects. How old is the earliest mammalian fossil. The earliest mammalian fossil dates back to 145.5 million years ago with the emergence of monotremes, marsupials and placental mammals. These mammals evolved from synapsids and therapids that existed before. Describe the animal the fossil came from. The animal, according to analysis, came from a small mammal that fed on insects and fed at night because of the dominance of dinosaurs at the era. What are synapsids. These are amniotes that existed in Carboniferous-Permian period about 320 million years ago. They had distinct features such as a temporal opening in the jaw. They evolve to have more mammal-like features. Fro synapsids other sub-classes emerged including the therapids. The
