100 million years in a piece of amber was probably the smallest dinosaur ever discovered. Similar to the bird’s skull of an animal less than two centimeters long, the journal Nature describes . Based on these remains, scientists suggest that this dinosaur was the size of a hummingbird-bee – the smallest bird of all living.
The dinosaur lived in the Mesozoic era (lasted from 250 million years to 65 million years ago) and weighed about 2 grams.
“He’s opening up a whole new family tree for us for birds, ” said Jinmai Connor, a paleontologist at the Chinese Academy of Sciences. Scientists called the discovered animal Oculudentavis khaungraae (“tooth-eyed bird”).
A drop of amber, in which the skull of an animal was enclosed, was found in Kachin state in northern Myanmar. The tiny beak is crammed with dozens of sharp teeth. With their help, the animal hunted insects and small invertebrates. Based on the size of the discovered remains, scientists concluded that the miniaturization of birds occurred much earlier than previously thought.
