Alioramus is a Tyrannosaur (about the size of a man, quite small by Tyrannosaur standards) that appeared in the 1st episode of Primeval: Volcano Chronicles, as a predator of Saurolophus, it also made a bruital attack on a little girl (was really after the scent of her dog, that was imbeded on her bram) at a German National park, where the Anomaly opened. Only one Alioramus was seen (a young male), but his pack could be heard calling him through the Anomaly back to his own era.
