Venatoraptor

Venatoraptor is an extinct genus of bird-like theropods from the Late Cretaceous (Maastrichtian, about 70-66 mya) of what is now northwestern Madagascar. It was one of the larger species of carnivorous Maniraptorids, growing up to about 24 feet long and about 6.6 feet tall, as well as weighing nearly 1,200 lbs. It was not a Dromaeosaur, despite its appearance, but it was due to convergent and was related to Rahonavis and may have probably been a ground-dwelling bird instead, and was likely a main rival of of Majungasaurus due to its size. It may have been most likely a solitary hunter thanks to its size, so it may have not needed to hunt in packs. It is unknown on why Venatoraptors became extinct, but it may have been due to the effects of the asteroid/comet that struck the Gulf of Mexico at the end of the Age of Dinosaurs.
