How a Single Tooth Changed What We Know About Raptor Evolution

When it comes to paleontological discoveries, sometimes the smallest fossils yield the most significant insights. In 2012, a single tooth found in Japan revolutionized our understanding of raptor dinosaurs, challenging long-held assumptions about their evolution and geographic distribution. This tiny fossilized tooth, measuring just a few millimeters in length, provided evidence that would rewrite scientific ...
