Evolution – Fossil History

Lizards have a long and complex fossil history that spans back to the Late Jurassic period, around 160 million years ago. The earliest known lizard-like reptile was the Megachirella, which lived in what is now modern-day Italy about 240 million years ago. However, Megachirella is not considered a true lizard, but rather an early ancestor of lizards and snakes.

The oldest true lizard fossils are from the Late Jurassic period and are similar in appearance to modern-day geckos. By the Early Cretaceous period, around 120 million years ago, lizards had diversified and spread throughout the world.

Fossil evidence shows that lizards underwent major radiation during the Eocene epoch, around 56-34 million years ago. This radiation led to the evolution of many of the major lizard groups we see today, including geckos, iguanas, skinks, and chameleons.

One of the most remarkable fossil discoveries related to lizards is the fossilized remains of a small lizard found preserved in amber from the Early Cretaceous period. The lizard, named Eocene Pristiguana, is estimated to be around 99 million years old and is one of the oldest known examples of an amber-preserved lizard.

Overall, the fossil history of lizards provides important insights into their evolution and diversification over time, and has helped us to better understand the origins and relationships of modern-day lizard species.
