Heyuan is a city in the mountainous Guandong province of China that bills itself as the "Home of the Dinosaurs," and rightfully so. In 2004 the local museum was awarded a Guinness World Record for the largest collection of fossilized dinosaur eggs (10,008 at the time), and almost 17,000 egg fossils have been found there since 1996. That number just grew a tiny bit larger after workers stumbled upon 43 fossilized dinosaur eggs in the red sandstone beneath the roads they were repairing. Some measured up to 5 inches across, and 19 of them were fully intact.

Heyuan is not just a hotspot for fossilized eggs — 11 fossilized skeletons and almost 200 footprint fossils have been discovered since 2006, according to a 2008 report from China Daily. While it's too early to tell what species the eggs belong to, other eggs found in the area date between 65 and 89 million years old.
