The beautiful mystery of feathers in amber. Are they from dinosaurs?

Mike: I saw this feather trapped in amber on

your page. It’s beautiful—but also kind of mind-blowing. Are feathers in amber even real? Like… how?

Me: Great question. Yes, they’re 100% real. What you’re looking at is a Cretaceous-era feather, preserved for nearly 100 million years in Burmese amber. And believe it or not, feathers like this have helped reshape what we know about dinosaurs.

Mike: Wait, dinosaurs had feathers?

Me: Some of them definitely did. Especially a group called the coelurosaurs—theropods closely related to birds. Feathers like the ones we find in Myanmar amber don’t just tell us about bird ancestors—they might be direct samples from dinosaurs themselves.

Mike: So what kind of feathers are these?

Me: Let’s start with the one you're seeing first. This one has something incredibly special—a feature we call a "double rachis" structure. That refers to the tiny microscopic hooks (called barbicels) that help feather strands interlock. This type of structure points to advanced feather development, possibly for flight or thermal regulation.

Mike: I didn’t even know feathers could fossilize.

Me: That’s the magic of amber. In normal rock fossilization, soft tissues decay long before they can mineralize. But amber—fossilized tree resin—can trap and protect delicate structures like feathers, hair, or even internal organs. You get detail at the micron level.

Mike: This one looks like it has two feathers. Is that rare?

Me: That second piece you’re referring to is even more spectacular. It contains two full feathers, and they’re preserved with rich contrast—look at those interlocking barbs and the central shaft or rachis. This is museum-grade material, the kind of specimen that would be referenced in scientific journals. Possibly part of a contour feather, or even a tail plume from an early bird or small dino.

Mike: You said this is Burmese amber?

Me: Correct—technically it’s from the Hukawng Valley in Myanmar. This amber dates to the mid-Cretaceous, about 98–100 million years ago. It’s some of the only amber on Earth that captures feathers this well. There’s a famous 2016 study where paleontologists even found an articulated dinosaur tail with feathers in Burmese amber—barbs, rachis, pigmentation, everything.

Mike: Whoa. This stuff should be in a museum.

Me: Some of it is. But thanks to careful sourcing and the ethical trade of amber fossils, private collectors now have the chance to own pieces that were once only seen in academic vaults. The specimens you're seeing today were hand-selected and polished for maximum visibility.

Mike: Is there a chance the feathers are modern?

Me: That’s a fair question. There’s a lot of misinformation online about fake or modern inclusions in amber. But these pieces have been lab-analyzed and come from layers where we also find extinct insects and Cretaceous plant material. The context matters. Also—modern feathers simply don’t preserve this way. You don’t get oxidation patterns, fossilized detritus, or the brittle fracturing we see here.

Mike: How many of these do you find?

Me: Very few. Out of thousands of Burmese amber pieces I’ve examined, only a tiny fraction contain identifiable feathers. Most are too broken, too dark, or show only partial barbules. These two—especially the double ratchet one—are as good as it gets for collectors.

Mike: Are these available for sale?

Me: Sometimes. Right now, both of these are from my personal showcase collection. But I do occasionally release pieces with feather inclusions to the public. If you’re subscribed to the paid newsletter or following the livestreams, you’ll get the first chance to claim them.

Mike: What if I want to learn more about this stuff?

Me: Here are some great starting points:
