The unprecedented discovery confirms scientists suspicions that the two-legged bird-like dinosaurs were doting parents, which not only incubated their eggs, but also guarded them at times putting their own lives at risk. Dinosaurs preserved on their nests are rare, and so are fossil embryos. This is the first time a non-avian dinosaur has been found, sitting on a nest of eggs that preserve embryos, in a single spectacular specimen, says study co-leader Shundong Bi, a paleontologist at the Indiana University of Pennsylvania.
