The reptile venom is actually older than the snakes themselves. The venom glands go back to about 200 million years ago, right at the dawn of the dinosaur era, and long before Tyrannosaurus rex roamed the planet. The best guess by paleontologists is that snakes are around 100 - 120 million years old. However, venom glands originated much earlier in ancient late Triassic lizards.
