A dinosaur nest discovery has revealed the most primitive known dinosaur embryos, which are among the oldest ever found.
The eggs belong to Torvosaurus, a T. rex-like predator that stalked the late Jurassic some 150 million years ago. Torvosaurus grew to be around 30 feet (9 meters) long, but the fragmented embryos discovered in Portugal were probably only about 6 inches (15 centimeters) in length.
"This is shedding some light on the early stages of the development of these types of dinosaurs," said Ricardo Araújo, a doctoral candidate in paleontology at Southern Methodist University in Texas. [See Photos of Dinosaur Embryos and Hatchlings].
