Paleontologists have identified embryonic remains of five kinds of dinosaurs, but intact embryos of the long-necked, lumbering sauropods remained unknown--until now. On page 2444, three paleontologists describe the first articulated skulls--not much bigger than a postage stamp--of titanosaurs, a group of sauropods known only from incomplete skeletons and very few skulls. The embryos may shed light on early sauropod evolution, about which relatively little is known.
