A tiny new species of bird-like dinosaur has been discovered, preserved in a lump of 99-million-year-old amber. The tooth-filled skull is only 7.1mm long, suggesting that this ancient creature would have been the size of a hummingbird – far smaller than other dinosaurs known from that time. Unusual features include large, side-facing eyes and a large number of sharp teeth suggesting a predatory lifestyle. The species has been named Oculudentavis khaungraae and is evidence of previously unimagined biodiversity in the Mesozoic era.
