How did dinosaur discoveries continue to reshape our understanding of prehistory in 2025?

The answer

Among the 70+ new species described by the American Museum of Natural History in 2025 were previously unknown feathered dinosaurs, adding to the growing body of evidence that feathers were far more widespread among dinosaurs than once believed. These fossil discoveries, made from rock formations spanning multiple continents, revealed new details about dinosaur diversity, behavior, and evolution. Some specimens showed evidence of display feathers used for mating rituals rather than flight, suggesting dinosaurs had complex social behaviors similar to modern birds. The steady pace of dinosaur discovery - roughly 50 new species are named every year - means we're living in what paleontologists call the 'golden age of dinosaur science.'
