The Nothronychus was from the Upper Cretaceous Period. It was an herbivorous theropod with a beak, whose name means Sloth Claw. It had heavy curved sloth-like claws that it may have used for gathering plants for food. It had four-toed feet, with all four toes facing forward.
As with many dinosaurs, it is likely to have had some parts of its body covered with primitive feathers.
