Paleontologists Hit a Dinosaur Jackpot in Italy - Gizmodo
The site is a quarry in Villaggio del Pescatore, a northeastern Italian town.Dinosaurs were first found there in the 1980s, and in the years since more and more fossils have come out of the rock.
The species was named 15 years ago, but until now the general thinking was that the animals lived about 70 million years ago and were relatively small, based on the complete individual that was previously excavated.
The new fossil evidence indicates the animals lived some 10 million years earlier and grew much larger.
(Komodo dragons in Indonesia and dwarf elephants on Malta during the Pleistocene are two such examples.) The discovery of larger dinosaurs indicates that Antonio was not a small adult hadrosaur but a normal-sized youth.
