Please do not overestimate the the size of this sample. This is a big piece of old feather (most probably from dinosaur) in Burmite. Please understand that the discovery of feathers in amber is very very rare and difficult! Ancient or fossilized feathers are feathers preserved in ancient fossils. These feathers can come from dinosaurs, ancient birds, ancient theropods, and other prehistoric creatures, providing valuable clues for studying the ecology and evolution of ancient animals. Dinosaurs are one of the most common sources of ancient feathers. Studies have shown that certain dinosaur groups, such as the Tyrannosauridae and Dromaeosauridae, may have had feathers or feather-like structures.
