It's name is Siats. it was discovered only recently and it was the apex predator in the Cenomanian, between 95 and 100 mya. It had the third longest femur between North American predator, and it was about to 30 feet long with a mass of over 2 t - the found specimen, however, it's a juvenile: an adulthood specimen may have been even bigger.
