The Night Feeder was a monstrous, enigmatic dinosaur that brutally killed its victims at night and was able to attack with unnatural stealth and speed. It is so fast that it has never been sighted, only it's kills have been seen since it leaves whatever it kills just laying there dead, most of the time brutally slashed apart. This suggests that it doesn't eat what it kills and just kills for fun. It has been seen using it's claws to cut right through trees with zero struggle or even any effort.
