2 years, 12 months ago2 years, 12 months agoI am currently investigating some possible feathers from the Hell Creek Formation. How does one tell the difference between fossil feathers and structures such as plant fibers?
Greetings @michael-deak ! You might have better luck with your inquiry if you contact Scott Wing at the Smithsonian. He is a paleobotanist with considerable experience with Hell Creek flora.
