"Discovery of New 'Hell Chicken' Dinosaur Challenges Extinction Theory"

A new study challenges the belief that dinosaur diversity was declining before the asteroid impact 66 million years ago. Researchers discovered a new species of birdlike dinosaur, Eoneophron infernalis, in the Hell Creek Formation, suggesting that dinosaur populations were stable and potentially even increasing in diversity. The findings indicate that there are still new dinosaur species to be discovered and support the idea that the perceived decline in diversity may be due to sampling and preservation biases. This discovery adds evidence that caenagnathids were thriving before the asteroid impact.
