Embryo of Colossal Dinosaur Was Preserved for 90 Million Years

The discovery of the 15-inch-long (38 centimeters) embryo is remarkable, said study co-researcher Darla Zelenitsky, an assistant professor of paleontology at the University of Calgary in Alberta, Canada. "This is the first embryo known for a giant oviraptorosaur, dinosaurs that are exceedingly rare," Zelenitsky told Live Science in an email. Moreover, it's only the second species of giant oviraptorosaur on record, Zelenitsky said.
