Recently, a team of researchers from the University of Washington and the National University of La Plata in Argentina have discovered the oldest evidence of egg-laying in South America. The scientists found fossilized eggshells from over 66 million years ago in the Patagonian region of Argentina. This is the earliest evidence of egg-laying in South America, and it sheds light on the evolution of the region’s unique fauna. This discovery provides evidence that egg-laying was present in the region during the age of the dinosaurs, and it has implications for the evolution of egg-laying mammals.

This exciting discovery is a reminder of the many fascinating fossils still waiting to be found in the Patagonian region of Argentina. It’s a reminder that even though the age of the dinosaurs may have ended millions of years ago, their legacy is still around us, and there is still so much more to learn about the evolution of life on Earth.
