Nothing you could find in any hen house could prepare you for the 11.5-foot tall, 500-lb. behemoth that roamed the landscape 66-million years ago in what is today North and South Dakota. Three fossils from the fossil-rich Hell Creek Formation have been nicknamed the “chicken from hell,” and represent the new species Anzu wyliei. The official word on what these birds looked like and where they spent their days appears in PLOS ONE this week. The unofficial word on the street is that animal activists are already scheming on how to resurrect this long-dead bird to strong-arm hapless chicken farmers into compliance. SQUAWK!
