The 99-million-year-old dinosaur feathers in a chunk of amber

Paleontologists have discovered a piece of the tail of a 99-million year dinosaur—complete with bones, soft tissue, and feathers—preserved in amber that was found in Kachin state, in northern Myanmar, according to a report published Thursday in the journal Current Biology. The tail, slightly curved with barbs jutting out, can be seen with the naked eye inside the fossilized tree resin. Most of the amber mined in the area is used to create jewelry, and this prehistoric sample had already been cut and shaped when it was collected by researchers, according to National Geographic.

The researchers, led by the paleontologist Lida Xing, of the China University of Geosciences, concluded the tail belonged to a young coelurosaur that lived during the Cretaceous period. Coelurosaurs are members of a group of theropod dinosaurs that encompasses tyrannosaurs and maniraptorans, the classification that includes the dinosaurs alive today—birds. The owner of this tail likely was not capable of flight, based on certain qualities of its structure, according to the researchers.

The discovery builds on a stack of existing research that supports evidence for feathered dinosaurs. Feathery fossils have been found elsewhere in Myanmar, as well as in the United States, Canada, France, Japan, and Lebanon.
