Titanosaurs Laid Eggs in Cold Regions, New Study Reveals
Summary
A new study suggests titanosaurs laid eggs and reproduced in cold, high-latitude regions near the South Pole, overturning the long-held belief that they nested only in warm areas. Fossilized eggshells from southern Argentina indicate they may have used mound-shaped nests heated by decaying vegetation.
Key Points
- Scientists found 255 fossilized titanosaur eggshell fragments in the Chorrillo Formation in southern Argentina.
- The discovery suggests titanosaurs reproduced at high latitudes, even in cold regions near the South Pole.
- Researchers think the dinosaurs used mound-shaped nests made of soil, sand, and vegetation to generate warmth and protect the eggs from drying out.
- The study challenges the earlier assumption that titanosaurs nested only in warm, near-equatorial environments.
