Geologists have discovered hundreds of fossilized nests each containing clutches of eight dinosaur eggs. The eggs were located in sand banks in Tamil Nadu in Southern India.

The nests were buried under volcanic ash believed to have come from the Deccan Trap eruptions. These eruptions were among the biggest ever, and produced lava flows hundreds of miles long and enormous volumes of climate-changing gases, which may have caused the widespread extinctions of dinosaurs that occurred at the time.
