...that all the details of the dinosaur-bird link have been ironed out. While current thinking favors speedy predators like velociraptors as the direct ancestors of modern birds, both Chiappe and Norell argue that the birds' forebears could just as easily have been troodontids like Mei long or even oviraptors, another related type of dinosaur. (Several years ago in Mongolia, Norell and colleagues unearthed a fossil oviraptor sitting on its egg-filled nest.) And then there's also the open question of how flight evolved. Mei long, says Chiappe, was clearly sleeping on the ground. But if flight began...
...variety of dinosaur nests and eggs from around the world. Visitors can see and touch real dinosaur bones and a dinosaur nest nearly eight feet in diameter. The exhibit presents new theories about dinosaur reproduction and general behavior. Other attractions include the longest eggs ever discovered born of an oviraptor from China, a 75 million-year-old titanosaur egg the size of a bowling ball and a DVD presentation on baby dinosaurs and embryos. Runs through Sept. 1. $7.50 adults, $6 seniors/students. Harvard Museum of Natural History, 26 Oxford...

They were mean and bloodthirsty, sure, but such dinosaurs as Tyrannosaurus rex may well have had a more caring side. The clue is the discovery of a fossilized embryo from a carnivorous dinosaur: an oviraptor found in Mongolia. The embryo was lodged in a nest, which also contained bones from other tiny dinos that mother oviraptor might have eaten while watching over her sharp- toothed darlings. Apparently even prehistoric monsters knew how to parent...
Even if there had been no other fossils in the nest, the discovery of an embryonic oviraptor would have been important. Dinosaur embryos are rare -- fewer than a dozen kinds have ever been found. Juvenile animals often have features that vanish as the creatures grow, but which also exist in the embryos of their precursors or descendants (human fetuses, for example, start out with tiny tails). If researchers can find common traits in unhatched dinosaurs and birds, they will be able to establish stronger links between them...
