A baby dinosaur, one of the most important finds this century, has been unveiled by palaeontologists. The hatching fossil, dating from 113 million years ago, provides an astonishing range of insights into dinosaur biology, according to Dr. Christiano Dal Sasso of Milan's museum of natural history and Dr. Marco Signor of the University of Napoli and Bristol University. It is the first dinosaur found in Italy and the only one in the world to show its internal organs.
