It is the earliest unquestionable reptile (Westlothiana is older, but in fact it may have been an amphibian, and Casineria is rather fragmentary).
How old is Hylonomus?
about 315 million years ago
Hylonomus lived about 315 million years ago, during the time we call the Late Carboniferous Period. This time period is also known as the Pennsylvanian and as the Coal Age.

Did humans come from reptiles?
Scientists have uncovered the link between the hair of mammals, the feathers of birds and the scales of reptiles. And the discovery, published today in the journal Science Advances, suggests all of these animals, including humans, descended from a single reptilian ancestor approximately 320 million years ago.
Did dinosaurs come before reptiles?
Summary. The earliest amniotes appeared about 350 million years ago, and the earliest reptiles evolved from a sauropsida ancestor by about 315 million years ago. Dinosaurs evolved around 225 million years ago and dominated animal life on land until 65 million years ago, when they all went extinct.
What is the last dinosaur alive?
For now, however, the 65-million-year-old Triceratops is the world’s last known surviving dinosaur.
