(CNN) — The complete skull of a previously unknown species of bird-like dinosaur was found in a Myanmar mine, trapped in a chunk of 99-million-year-old amber. Researchers say it’s a fossil of the smallest dinosaur ever found.
It’s smaller than the size of the tiniest hummingbird alive today.
Its head was the size of a thumbnail.The jaw was packed with more than 100 serrated teeth, and its eyes were bulging and lizard-like. Despite its tiny stature, researchers say the creature was likely a predator.
A paper on the fascinating find was published Wednesday in the journal Nature.
