For the first time, scientists have found the remains of babies from the group of meat-eating dinosaurs that includes Tyrannosaurus rex. Researchers said recently that the jaw and claw bones show that the large babies looked a lot like adults and were “born ready” to hunt. The bones, also called fossils, represented two species from the group called tyrannosaurs. Tyrannosaurs were the top hunters in Asia and North America toward the end of the dinosaur age. The bones suggested that these babies were bigger than any other known dinosaur babies.
