Question 1

How do you say Struthiomimus?

Accepted Answer

You say it like this: STRUTH-ee-oh-MY-muss. The first part rhymes with truth. Break it into four chunks and say each one slowly before putting it together. The stress lands on STRUTH at the start and MY in the middle. Once you say it a few times it starts to feel totally natural, and you will be the only one at school who can say it correctly.

Question 2

What does Struthiomimus mean?

Accepted Answer

The name means ostrich mimic and it comes from two Ancient Greek words. Strouthios referred to the ostrich in Greek, and mimos means imitator or mimic. Paleontologist Lawrence Lambe chose the name in 1902 because the dinosaur looked so much like a modern ostrich with its long legs, long neck, toothless beak, and upright posture. It is one of the most accurate and descriptive names in all of paleontology.

Question 3

How fast was Struthiomimus?

Accepted Answer

Scientists estimate Struthiomimus could run at speeds of around 50 kilometers per hour, which is about 31 miles per hour. That makes it roughly as fast as a modern racehorse. Researchers figured this out by studying the proportions of its leg bones, specifically the fact that its lower leg was longer than its upper leg, a classic sign of a fast runner seen in modern ostriches and emus. It was almost certainly one of the fastest dinosaurs of its time.

Question 4

Was Struthiomimus dangerous?

Accepted Answer

Struthiomimus was not a predator and was almost certainly not dangerous to large animals or humans. It had no teeth at all, just a hard keratinous beak. Its hand claws were long but curved and more suited for pulling branches than attacking prey. Its main defense was its speed. If threatened by a predator like Albertosaurus, Struthiomimus would almost certainly just sprint away rather than fight back.

Question 5

What did Struthiomimus eat?

Accepted Answer

Scientists believe Struthiomimus was an omnivore, meaning it ate both plants and animals depending on what was available. Its toothless beak and likely diet of leaves, fruit, and seeds made plant material a big part of its menu. But it probably also snapped up insects, small lizards, eggs, and other small creatures when the opportunity arose. This flexible diet is very similar to how modern ostriches feed today, eating whatever is easiest to find.

Question 6

Did Struthiomimus have feathers?

Accepted Answer

Yes, and we actually have fossil proof. In 2012 paleontologist Darla Zelenitsky and her team from the University of Calgary described three Struthiomimus fossils that showed clear traces of feathers preserved as dark carbon marks in the rock. The fossils revealed long feathers on the arms, shorter body feathers on the torso, and bare scaly skin on the lower legs, almost exactly like a modern ostrich. This was the first direct physical evidence of feathers in any ornithomimid dinosaur.

Question 7

When did Struthiomimus live?

Accepted Answer

Struthiomimus lived during the Late Cretaceous Period, roughly between 72.2 and 66 million years ago. That puts it in the final chapter of the age of dinosaurs, right alongside famous animals like Triceratops and Tyrannosaurus rex. It survived until the very end of the Cretaceous, meaning it was among the last non-avian dinosaurs alive before the asteroid impact ended their era 66 million years ago.

Question 8

How big was Struthiomimus?

Accepted Answer

Struthiomimus was about 14 feet long, or 4.3 meters, and weighed around 330 pounds, which is roughly 150 kilograms. That is about the same weight as a large male lion but with a completely different body shape: long legs, a stretched-out neck, a tiny head, and a stiffened tail held out behind for balance. It was not a giant dinosaur but it was bigger than most people expect when they first hear its name.

Question 9

Where have Struthiomimus fossils been found?

Accepted Answer

Most Struthiomimus fossils have been found in the province of Alberta in Canada, particularly in Dinosaur Provincial Park and the surrounding badlands. The Dinosaur Park Formation and the Horseshoe Canyon Formation have produced the most specimens. A few fragmentary remains have also been found in the United States. Alberta's badlands are one of the best places in the entire world to find Late Cretaceous dinosaur fossils because erosion constantly exposes new bones.

Question 10

Is Struthiomimus related to T. rex?

Accepted Answer

They are both theropod dinosaurs, so they share a common ancestor deep in evolutionary history, but they are not closely related in the way that cousins are. Struthiomimus belongs to a group called Ornithomimidae, the ostrich mimics, which is a very different branch of the theropod family tree from the tyrannosaurs. Struthiomimus was actually much more closely related to birds than T. rex was. Think of them as being as different from each other as a modern eagle and a modern crocodile.

Question 11

How many Struthiomimus fossils have been found?

Accepted Answer

Dozens of Struthiomimus specimens have been recovered over the past century, making it one of the more commonly found dinosaurs in the Late Cretaceous of Alberta. Its abundance in the fossil record at Dinosaur Provincial Park suggests it was genuinely common as a living animal too, possibly moving in loose herds across the ancient floodplains. Having many specimens has allowed scientists to study bone growth, estimate speed, and even find feather impressions, giving us an unusually detailed picture of this dinosaur.

Question 12

Who discovered Struthiomimus?

Accepted Answer

Struthiomimus was first collected by Lawrence Morris Lambe, a Canadian paleontologist working for the Geological Survey of Canada. He found the first fossils in 1902 along the Red Deer River in Alberta. Lambe formally described and named the species Struthiomimus altus based on that original material. He was one of the pioneering figures of Canadian paleontology and named several other important dinosaurs from the same region during his career.
