Discovery of Mass Death Site Bolsters Theory That Tyrannosaurs Hunted in Packs

A remarkable fossil site in Utah, in which several tyrannosaurs were found buried together, strengthens a burgeoning theory that these fearsome creatures hunted in packs, similar to wolves. That tyrannosaurs were social hunters is a possibility paleontologists have been considering for more than 20 years. Back in 1910, paleontologists working in Alberta, Canada, discovered the…

2.5 Billion T. Rex May Have Roamed Earth

In total, some 2.5 billion Tyrannosaurus rex may have reached maturity and marauded the Cretaceous landscape, according to a new study published today in the journal Science.

Dinosaur Found in Argentina Looked Like a Bumpy-Headed T. Rex

Eighty million years ago, a large dinosaur curled up and died in what is today western Argentina. The dinosaur was a bipedal, meat-eating predator from the little-known family Abelisauridae, which could grow to nearly 30 feet long and are characterized by their stubby, rugged skulls. This particular abelisaur, dubbed Llukalkan aliocranianus, is a newly identified species.…

Tyrannosaur Teens Didn’t Have the Bone-Crushing Bite of Adults

Adult tyrannosaurs were basically bone crushing machines on two feet. New research suggests juvenile tyrannosaurs couldn’t match the same level of brutality, resulting in a distinctive bite that set them apart from their adult counterparts. Nothing like tyrannosaurs exist today, and thank goodness for that. As the quintessential apex predator of the Mesozoic, these megatheropods…

Who Would Win the Battle Between the Largest Prehistoric Snake and a Tyrannosaurus Rex?

The Titanoboa was a one-ton, 48-foot-long snake who lived 58-million years ago. Scientists thought it couldn’t exist. Yet, they discovered its fossil in Cerrajón, Colombia. She was a constrictor that could kill anything with a pressure of 400 pounds per square inch. That’s the equivalent of being under three Eiffel Towers. The people at the…

Tyrannosaurus on a truck might be the scariest thing you’ll see on your commute

These model dinosaurs are out for a Sunday drive, enjoying a little fresh air before they head to their next destination. Still, if I saw T-Rex staring down my windshield, I might get in the other lane. Just in case. [reddit]

Try as he might, there are some things T-Rex just can’t do

Pity the poor Tyrannosaurus. With those teeny little arms and that great big body, T-Rex is incapable of doing things that come easily to you and me. Hugh Murphy draws the series “T-Rex Trying…” which shows a T-Rex stuck in the modern age, trying (and usually failing) to do things no short-armed creature was ever…
