Belonging from the genus of Coelurosaurian Theropod dinosaur, these not so gentle monsters were a menace. With bird sized brains, they created more havoc than could have been repaired. One of the largest land predators these dinosaurs could have a length of 40 ft. And the weight of about 6.8 metric tonnes. It was an opportunist carnivore.
