Summary:

- The study found that lizards and snakes are 35 million years older than previously thought, dating back to the Late Cretaceous period around 100 million years ago.
- This new timeline is based on an analysis of fossil and genetic data, which provides a more accurate picture of the evolutionary history of these reptiles.
- The findings suggest that lizards and snakes diverged and diversified much earlier than the mass extinction event that wiped out the dinosaurs, allowing them to thrive and spread across the globe.
