For instance, the apex predator of the South American pampas, the coelurosaurian "cutlasstooth", has evolved huge, cutting teeth to allow it to prey upon large sauropods. The pampas is also home to the last of the tyrannosaurids, the large scavenging "gourmand". There are also various dromaeosaurids, including the "jinx", adapted to mimic larger herbivorous dinosaurs through scent and appearance.
