It had a bird-like beak that was full of teeth, with 29 or 30 teeth identified.
The team says this discovery opens up a new world of previously unknown creatures, with new technologies allowing scientists to identify species trapped in amber millions of years earlier."We are only just at the very beginning of what we can discover about small animals from this amber locality," O'Connor said.
