Scientists discovered remarkably preserved dinosaur-era bird wings trapped inside amber for nearly 100,000,000 years, with feathers and tissue still visible

Well, no.
Modern birbs became a proper distinct group around that time (no teeth, modern wing structure, etc).
They cohabited with proper dinosaurs & flew around along with “pterosauromorpha” (flying lizardos). (At the time they didn’t have any flying mammals tho.)
And the distinctions come from bone structures & the few feathers that we discovered - so if someone with knowledge would say that feather came from a bird (with features found in modern birds today) and not a dinosaur, I would be inclined to believe them.
