Image Credit: PubMed Central A new fossil discovery gives us a fascinating glimpse into the lives of dinosaurs long before birds existed. Scientists have found a remarkably well-preserved 70-million-year-old dinosaur embryo inside an egg in southern China. The embryo, from an oviraptorid (a type of theropod dinosaur ), is curled up in a posture strikingly similar to modern bird embryos just before they hatch. This “tucking” position helps birds hatch successfully, and the fossil suggests that dinosaurs were doing something very similar millions of years before birds evolved. Fossil embryos are incredibly rare, and this one shows behavio
