Fossils Reveal Dinosaurs Once Lived at the South Pole
Antarctic rock layers from the early Cretaceous contain bones of plant-eating dinosaurs that thrived in polar forests where summer daylight lasted for months. These fossils show that the continent was once covered in dense woodlands rather than ice, proving dinosaurs lived closer to the South Pole than any land animal today. Scientists identified two new species whose growth rings in bones prove they stayed year-round despite long winter darkness.
💡 Fun detail:
Some bone slices show growth pauses every dark winter, proving these dinosaurs hibernated or slowed down like bears instead of migrating thousands of miles.
