“Megaraptorid claws are the stuff of nightmares – razor-sharp meat hooks more than a foot long. Wolverine from the X-Men has nothing on these guys,” Lamanna said.
Scientists discovered the remains of the mysterious dinosaur in Argentina's Patagonian region.
“Not many megaraptorid specimens are known, so we thought the new fossil would provide important information on these enigmatic predators,” said study co-author Domenica dos Santos of the Museum of Natural Sciences at the National University of Comahue in Argentina.
The new megaraptoid is also thought to be one of the youngest and most deadly dinosaurs that survived until the end of the Age of Dinosaurs.
"It was one of the last megaraptorids that lived on our planet and one of the largest in size for its time," lead study lead researcher Juan Porfiri, coordinator at the Museum of Natural Sciences at the National University of Comahue, told Live Science.
Scientists at the Carnegie Museum of Natural history said they still know very little about the new megaraptoid and that there is a lot to learn about this poorly understood dinosaur.
