Question 1

How do you say Gorgosaurus?

Accepted Answer

Gorgosaurus is pronounced GOR-go-sore-us. Break it into four syllables: GOR, like the word gore, then go, then sore, then us. Put the strongest stress on the first syllable, GOR. A good memory trick is to think of it as 'gorgeous dinosaur' but swap gorgeous for GOR-go and add sore-us on the end. Once you say it a couple of times, it feels completely natural.

Question 2

What does Gorgosaurus mean?

Accepted Answer

Gorgosaurus means 'Gorgon lizard' or 'fierce lizard.' The first part of the name, Gorgo, comes from the Greek word for Gorgon, which was a terrifying monster in ancient Greek mythology whose gaze could turn people to stone. The second part, saurus, comes from the Greek word sauros meaning lizard, and it appears in the name of nearly every dinosaur. Canadian paleontologist Lawrence Morris Lambe chose this dramatic name in 1914 to capture just how ferocious this predator must have been.

Question 3

How big was Gorgosaurus?

Accepted Answer

Gorgosaurus grew to about 26 to 30 feet long, which is roughly the length of two full-sized minivans parked bumper to bumper. It weighed somewhere between 4,400 and 6,000 pounds, making it heavier than a large rhinoceros but lighter than its famous relative T. rex. Despite its size, it was built more slenderly than T. rex, which scientists think made it faster and more agile. It was still absolutely massive compared to almost everything else alive in its ecosystem.

Question 4

Was Gorgosaurus as scary as T. rex?

Accepted Answer

In many ways, yes, and for animals living in its time and place, Gorgosaurus was every bit as terrifying as T. rex because it was the top predator in its ecosystem. It lived about three million years before T. rex appeared, so the two never actually met. Gorgosaurus may have been slightly smaller than T. rex but was probably faster, and it had the same powerful jaws packed with serrated teeth. One fossil even preserved its stomach contents, which included the remains of two juvenile hadrosaurs, giving a direct and sobering snapshot of how deadly it really was.

Question 5

Did Gorgosaurus hunt in packs?

Accepted Answer

This is one of the most exciting and debated questions in tyrannosaur science right now. Several Gorgosaurus skeletons have been found at the same location in Alberta's Dinosaur Park Formation, which has led some paleontologists to suggest they may have gathered or even hunted together. Most scientists are careful not to jump to conclusions because bones ending up in the same place could have other explanations, like flooding carrying multiple carcasses together. But the evidence is intriguing enough that serious researchers are actively investigating the possibility that Gorgosaurus had some level of social behavior.

Question 6

Where did Gorgosaurus live?

Accepted Answer

Gorgosaurus lived in what is now western North America, specifically in the region we call Alberta in Canada and the state of Montana in the United States. During the Late Cretaceous period, this region looked nothing like it does today. It was a warm, subtropical landscape of rivers, floodplains, and dense forests, more similar in feel to a modern-day Louisiana bayou than to the Rocky Mountain wilderness you see there now. Most of the best fossils have come from Alberta's Dinosaur Park Formation and Montana's Two Medicine Formation.

Question 7

How is Gorgosaurus different from T. rex?

Accepted Answer

Gorgosaurus and T. rex are both tyrannosaurids but they are separate genera with real differences. Gorgosaurus lived about three million years earlier, was somewhat smaller and more lightly built, and belonged to the subfamily Albertosaurinae rather than Tyrannosaurinae where T. rex sits. Gorgosaurus also has a slightly different skull shape and proportions. Scientists think its lighter build made it faster than T. rex, which was more massively constructed. They also lived in somewhat different environments, with Gorgosaurus roaming more northern regions of the ancient continent called Laramidia.

Question 8

Was a Gorgosaurus really sold for millions of dollars?

Accepted Answer

Yes, and it caused a huge stir. In July 2023, a nearly complete Gorgosaurus skeleton was auctioned at Sotheby's in New York and sold for 6.1 million dollars, making it one of the most expensive dinosaur fossils ever sold to a private buyer. Many scientists were concerned because fossils sold privately often disappear from public access, meaning researchers may never be able to study them. The specimen had been legally collected in Montana. The sale reignited a longstanding debate about whether valuable scientific specimens like this should be legally protected so they end up in museums and research institutions rather than private collections.
