Powerful X-ray imaging reveals new details of dinosaur embryos in eggs

To look at dinosaur embryos entombed inside 200 million year old fossil eggs, scientists used powerful X-rays to create detailed images. They wanted to see how these embryos compared to those of modern-day dinosaur relatives. Source: https://earthsky.org/earth/dinosaur-fossil-embryo-synchrotron-x-rays…

Why climate change is creating more female sea turtles and crocodiles
