Fossilized remains of a snake. The snakes evolved from monitor-like lizards some time toward the end of the Cretaceous Period (65 million years before present). The first types to evolve were the boas and pythons; the venomous snakes are not known before the Eocene Period (c.30 million years BP). (1991)
