It's interesting how simple observations can become breakthrough theses quite rapidly. Such a thing has happened recently, when prehistoric Canadian dinosaurs were discovered to have travelled in packs, effectively bullying other, less socially important dinosaurs. This discovery was made in the most part by examining tracks made in ancient clay. While there were many different species' tracks, the tyrannosaurus prints were aligned. There wasn't just one set going across the landscape, there was an entire pack's worth of full grown adult predators, all evidently hunting together. Like wolves, these beasts would hunt in packs in order to be more effective in their hunt and increase their chance of survival. Almost like the pack of bullies in elementary school, these guys would terrorize anything they could get their claws on. As cool and scary as it sounds, understanding exactly how dinosaur gangs effectively operated makes the entire study more accurate. This is a detail that is hard to find in paleontology, but one ever so crucial to finding out exactly how certain dinosaurs lived. This new discovery puts us one step closer to understanding the dinosau. The tyrannosaurus travelled in packs, just one more reason not to mess with them, just for future reference.
