An absolutely incredible discovery in China has made huge waves in the dinosaur community, and it’s all thanks to some construction workers. Workers who were trying to build a new school discovered about 30 dinosaur eggs dated about 130 million years old, an amazing finding that adds to the list of huge dinosaur discoveries in the area.

The workers were actually using explosives to destroy a boulder as part of the project, which is what makes it so fortunate that they didn’t destroy the eggs in the process. One of the workers noticed that there appeared to be eggs in the area, as well as shell fragments, so the project was halted so experts could come in and examine the site.

They found that the eggs likely belong to some oviraptorosaurian species, or bird-like dinosaur species. They were found in the city of Ganzhou in the Jiangxi Province of China, and more research will need to be conducted to learn more about what species they belong to.

“Oviraptorosaurs (“egg thief lizards”) are a group of feathered maniraptoran dinosaurs from the Cretaceous Period of what are now Asia and North America,” reads a Wikipedia excerpt on this type of dinosaur. “They are distinct for their characteristically short, beaked, parrot-like skulls, with or without bony crests atop the head. They ranged in size from Caudipteryx, which was the size of a turkey, to the 8 metre long, 1.4 ton Gigantoraptor. The group (along with all maniraptoran dinosaurs) is close to the ancestry of birds. Analyses like those of Maryanska et al (2002) and Osmólska et al. (2004) suggest that they may represent primitive flightless birds. The most complete oviraptorosaur specimens have been found in Asia. The North American oviraptorosaur record is sparse.”
