Fossil Poop Found in Montana May Explain How Birds Survived Dinosaur Extinction

Scientists are studying a bird fossil discovered in Montana, USA, that may shed light on how certain birds survived the asteroid impact that wiped out the dinosaurs. The specimen is believed to have belonged to a bird that was consumed by a Tyrannosaurus rex or another large predator. Researchers hope that fossilized fecal matter associated with the find could reveal key dietary and behavioral clues. Understanding what these ancient birds ate may help explain why some avian species endured the mass extinction event while others did not.
