Science, Oct. 3–Bird eggs have been admired since ancient times for their many hues and patterns, from the vivid blue of American robin eggs to the deep green-black of emu eggs. Now, a study shows these colors and markings are even older than we thought – they may have graced dinosaur eggs some 150 million years ago or more. “(This) is a true discovery,” says Mark Hauber, an ornithologist at Illinois who studies the evolution of bird eggs and brooding behaviors but was not involved in the research.
