How Ankylosaurs Got Their Clubs
While clubs are practically synonymous with ankylosaurs, we’ve only started to get to the bottom of how they worked and how this unusual anatomy developed in the first place.

Did Eating Insects Shrink These Dinos?
We often think of dinosaurs as either preying on other dinos or mammals, or as plant-eaters -- but in ecosystems today, those aren’t the only two options. So why would we expect dinosaurs to have only been carnivores or herbivores, with...

Why Do Things Keep Evolving Into Crabs?
For some reason, animals keep evolving into things that look like crabs, independently, over and over again. What is it about the crab’s form that makes it so evolutionarily successful that non-crabs are apparently jealous of it?

When Dinosaurs Chilled in the Arctic
All told, the Arctic in the Cretaceous Period was a rough place to live, especially in winter. And yet, the fossils of many kinds of dinosaurs have been discovered there. So how were they able to survive in this harsh environment?

The Giant Dinosaur That Was Missing a Body
From end to end, its forelimbs alone measured an incredible 2.4 meters long and were tipped with big, comma-shaped claws. But other than its bizarre arms, very little material from this dinosaur had been found: no skull, no feet, almost...

The Dinosaur Who Was Buried at Sea
Paleontologists have been studying nodosaurs since the 1830s, but nobody had ever found a specimen like Borealopelta before. The key to its exceptional preservation was where it ended up after it died and how it got there.

How Pterosaurs Got Their Wings
When pterosaurs first took flight, you could say that it marked the beginning of the end for the winged reptiles. Because, strangely enough, the power of flight -- and the changes that it led to -- may have ultimately led to their downfall.

How Dinosaurs Coupled Up
Dinosaur mating behavior has been the subject of a lot of speculation, but what can we actually say about it from the fossil record?

A Short Tale About Diplodocus' Long Neck
Long necks gave sauropods a huge advantage when it came to food, but not in the way you think. And this benefit would allow them to become the biggest terrestrial animals of all time!
