Hummingbird sized dinosaur discovery in amber

This 11 March 2020 video says about itself:

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.

A spectacular new amber fossil from Myanmar holds the skull of the smallest prehistoric dinosaur ever found: a bird-like creature that lived 99 million years ago and grew no bigger than the smallest birds alive today.

The fossil, described today in the journal Nature, measures just 1.5 centimeters long from the back of the head to the tip of the snout, about the width of a thumbnail. The skull’s proportions suggest that the animal was about the same size as a bee hummingbird, which would have made the newfound dinosaur lighter than a dime.

The tiny creature appears to be most closely related to the feathered dinosaurs Archaeopteryx and Jeholornis, distant cousins of modern birds. Researchers suspect that like those animals, the small dinosaur had feathery wings, but without more fossils, they can’t determine how well it flew. And despite its hummingbird-like proportions, the tiny dinosaur was no nectar feeder. Its upper jaw bristled with 40 sharp teeth, and its huge eyes—suited for spotting prey in the foliage—have features unlike any seen in other dinosaurs. Fittingly, the creature’s genus name is Oculudentavis, derived from the Latin words for eye, tooth, and bird.

A newly described fossil preserved in amber reveals that a 99-million-year-old creature called Oculudentavis, recently heralded as a hummingbird-size dinosaur, was more likely a bizarre type of lizard: here.
