This 100-Million-Year-Old Bird Trapped in Amber Is The Best We've Ever Seen

Scientists have uncovered an incredible specimen in Myanmar that has given us a glimpse of life from 100 million years ago - a piece of amber containing the remarkably preserved remains of an ancient bird hatchling. Inside the amber, you can make out the head, tail, and neck of the bird, but it's the wings and feet that are the real marvels - the chunk of fossilised tree resin has perfectly preserved the bird's feathers, flesh, and claws, and gives us insight into a doomed group of prehistoric species called the 'opposite birds'.

"Seeing something this complete is amazing. It's just stunning." The team suspects that the little bird fell into a pool of conifer sap soon after it hatched, and got trapped in the tar-like liquid. Interestingly enough, despite being such an important part of our understanding of the prehistoric world, scientists still aren't entirely sure of the exact chemistry at play in the amber preservation process. What we do know is that after animals get stuck in tree resin, it starts to harden, and if you have the right levels of pressure and temperature, it will transform into a semi-fossilised substance called copal. "Scientists don't agree on when resin officially becomes copal, or when copal officially becomes amber. Some say that amber must be at least 2 million years old, but that cutoff is arbitrary."
