"PhD Student Discovers 'Chicken from Hell' Dinosaur Species"

A new dinosaur species, Eoneophron infernalis, challenges the theory that dinosaur diversity was in decline before the asteroid impact that killed non-avian dinosaurs. The discovery suggests that caenagnathid diversity had been stable for millions of years before the impact, countering the argument of a decline based on the incomplete fossil record. The findings by researchers at Oklahoma State University indicate that there are still new dinosaur species to be discovered and support the idea that sampling and preservation biases may have influenced the perceived decline in diversity.
