Albertosaurus

''' A medium sized tyrannosaur.

Pre-Series (Alternate Timeline)
In 2006, an Albertosaurus goes through an anomaly into an abandoned warehouse. When Evan Cross and his wife Brooke Cross arrive to investigate the anomaly. The Albertosaurus then attacked and ate Brooke. (The New World, Fear of Flying)

It was about to eat Evan, when Mac Rendell, from the ARC, tackled Evan out of the way. He got up, but the Albertosaurus smacks him into the wall. Mac shoots it with his EMD, and it nearly falls, before it goes back into the anomaly. The ARC Mac dies of his wound. (Truth)

Pre-Series (New Timeline)
In the new timeline, instead of the Albertosaurus already being in the building, it runs out of the anomaly into what will become Cross Photonics, knocking Evan out of the way, and eating Brooke. It nearly eats Evan, but Mac (wearing a Canadian Army uniform) tackles him out of the way. Mac gets up to fire, but the Albertosaurus smacks him into the wall, and Mac shoots it, making it flee back into the anomaly. (Rewritten)

The Sound of Thunder: Part 2
An anomaly opens in an alleyway in near Future London, and the Albertosaurus that killed Brooke is chased back through by Connor Temple, Kieran Coles, and two other ARC members. However, before they could lock it, the Albertosaurus returned, and took Kieran into the 2006 Cross Photonics anomaly. It roams around the building. After Evan and Dylan help Kieran and Connor back into the Spaghetti Junction, the Albertosaurus returns and attacks them, but Hall sends in many troops, who fire many tranquilizer rifles into the Albertosaurus, rendering it unconscious.

It is transported into a semi-truck, to be brought back to the Project Magnet Laboratory for examination. However, it wakes up, breaks out of the truck, and goes on a rampage. It runs to a gas station, and rams into a car. Hall sends in troops to kill the creature. It sets fire to the station, and is about to ram into Leeds, when Dylan tackles him out of the way, making it ram Hall into a car, severely wounding, possibly killing him. Evan and Mac then arrive and use flamethrowers to send it back into the anomaly, so it can kill Brooke. Without the ARC Mac present, it nearly kills Evan's younger self, when Mac comes in and saves Evan. It presumably kills Mac, before returning into the Spaghetti Junction, and attacks Evan and Dylan, but Evan grabs his gun and shoots the Albertosaurus dead, in vengeance of Mac and Brooke's death.
