WASHINGTON (Reuters) - Scientists are marvelling over the exquisitely preserved skull of what appears to be the smallest-known bird - tinier than any hummingbird - encased in 99-million-year-old amber and boasting many odd traits including jaws studded with numerous puny teeth.
The skull, measuring about half an inch (14.25 mm) long, belongs to a bird called Oculudentavis khaungraae that lived during the Cretaceous Period in what is now northern Myanmar, the researchers said on Wednesday. None of the rest of the body was preserved, but the researchers estimated that Oculudentavis weighed about an ounce (28 grams) and measured 2 inches (5 cm) long including a hypothetical bony tail.
