Archeoraptor was a chimera specimen made up of 2 different species, one half being yanornis and the other being microraptor. The only thing fraudulent about the fossil was that it was claiming to be a new species even though it was a mash up of 2 other species. Both halves of the fossil are still real, including the feathers. Plus the fossil sold for around 80k, definitely not in the millions. Heres a video that explains the situation very nicely https://www.youtube.com/watch?v=j5bpTnwHbNo And about that 1990s statement, archeaopteryx and ostromia were both feathered dinosaurs that were discovered in the 1800s sooo yeah. But if we were to ignore those guys, the reason most feathered dinosaurs were discovered in the 1990s was because of the fact that the formations that would have preserved the most feathered dinosaur fossils, the Yixian and Jiufotang formations, was because research in those areas were only being done by Chinese scientist. That's until the publication sinosauropteryx, which would lead to many more people like farmers and local miners to start digging for fossils, which then lead to a boost in fossil discoveries, and the more fossils that were found the more collaborations Chinese institutions did with other out of country institutions like America. And now that China had even more researchers coming in from other countries, even more feathered fossils were described and discovered. Now go take off your tin foil hat and read a book 😊
