New research suggests the asteroid impact that killed the dinosaurs probably burned Earth's forests, requiring modern birds' common ancestors to live on the ground.
The fossilized find provides us with another example of the oldest bird species we know of.

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.

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.
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.
Types of dinosaurs include the lizard-hipped dinosaurs and the bird-hipped divisions of dinosaurs. Both of these types of dinosaurs probably shared a common ancestor during the Middle Triassic. How else are these dinosaurs related?
Dinosaur bones are all we have to study what these animals looked like and how they lived. Some of the most important dinosaur bones that paleontologists study come from the skull. Why is the skull so important?
It isn't hard to imagine this scene even though dinosaurs haven't walked the earth for millions of years. Dinosaurs have captured our imaginations. These dinosaur articles have been written to lead you into the exciting world of dinosaur research and back to the "Age of Dinosaurs."
