Dinosaurs

It isn't hard to imagine the world full of dinosaurs, even though these extinct animals haven't walked the earth for millions of years. Learn all about dinosaurs, including early dinosaur discoveries, dinosaur fossils, and dinosaur extinction.


The American Southwest was once prime tyrannosaur country, as a newfound skeleton reminds us.

Scientists are at odds about whether Velociraptors worked together to take down their prey.

Tyrannosaurus rex was a giant predator that roamed the earth, so why did it have such tiny arms?

Scientists generally agree that dinosaurs sported colorful, feather-like plumage. So do moviemakers lack imagination, or do audiences?

The colossal footprints of an herbivorous dinosaur found in western Australia might belong to the biggest dinosaur ever.

Based on some baby dinosaur teeth, scientists have figured out just how long dinosaur eggs incubated. (The answer? Long. Too long.)

And, to top it all off, it's got feathers on it.

A recent discovery of the partial skeleton of a small pterosaur calls into question whether flying reptiles of the Late Cretaceous were all humongous.

Spiclypeus shipporum was a dinosaur that roamed Montana 76 million years ago, and its unique horn structures set it apart from other horned dinos.

Nature is one big interconnected system. Learn how flowers and dinosaurs helped the dung beetle appear on the planet.

A new analysis of Rapetosaurus fossils can shed light on how certain dinosaurs socialized and evolved.

The new dino discovery of Timurlengia euotica in Uzbekistan shows that Tyrannosaurus rex ancestors evolved smarts before they got large and took charge.

Amateur fossil hunters discovered a new carnivorous dinosaur called Dracoraptor hanigani on the beaches of Wales.

Eggs are trickier than you might think.

Iguanodon continues to perplex us. Across the vastness of evolutionary time, she gives us a double thumbs-up. We just don't know if we should run or throw her a ripe mango.

OK, hop in your time machine and go back 67 million years or so to the Cretaceous period. Then find a Tyrannosaurus rex and challenge it to a race. Sounds crazy, huh? Could you really outrun a Tyrannosaurus rex?

The oldest record of a fossil dinosaur bones discovery is in a Chinese book written between 265 and 317 A.D. Learn more about dinosaur discoveries and the places they were made in this article.

The Late Cretaceous Period was an era of great transformation and was when the dinosaurs disappeared from the earth. Learn more about the Late Cretaceous Era and the dinosaurs that existed during it.

Modern dinosaur discoveries in the USA and Canada detail important discoveries in recent times. The United States and Canada are home to some of the most vigorous dinosaur research in the world. What are some of these discoveries?

Dinosaur evolution looks at how dinosaurs developed and changed over the course of time. Paleontologists study the different types of dinosaurs and how they are related to each other. How else is dinosaur evolution studied?

Dinosaurs became extinct at the end of the Cretaceous Period. How and why is a puzzle that paleontologists are trying to solve by studying fossils and rock formations. Learn more about the different extinction theories.

Interest in dinosaurs soared to new heights in the 1990s, thanks largely to the blockbuster film Jurassic Park. So too did dinosaur discoveries. Since 1990, more than 100 new dinosaur genera have been described and named. Learn more about recent dinosaur discoveries.

The recently discovered large theropod Abelisaurus comahuensis, from Patagonia is argentina, looked a little like Albertosaurus from Alberta, Canada, particularly in its size and lifestyle. Find out more about the Late Cretaceous dinosaurs.

Albertosaurus was an older "cousin" to the better-known Tyrannosaurus. In many ways the two were similar: the head was large compared to the body, the tiny forearms had only two fingers each is and the long tail balanced the body over two powerful back legs.Find out more about the Late Cretaceous dinosaurs.

Anchiceratops was discovered along the Red Deer River in Alberta in 1912. Learn more about the Anchiceratops and Late Cretaceous Dinosaurs.
