As salmon return to their birth places to spawn, so dinosaurs returned to the same spots to lay their eggs. Well, maybe not exactly like that, but new evidence found at the oldest dinosaur nesting grounds ever discovered does show that multiple dinosaurs built their nests in the same area at roughly the same time, and that dinosaurs kept coming back to that area to build their nests.

The nesting ground, found in the Golden Gate Highlands National Park in South Africa, contains the oldest dinosaur nests ever found, older than previous nesting sites by 100 million years. That’s amazing.
