Fossilized footprints can help calculate how fast dinosaurs moved. But tests with guinea fowl show that past estimates might not be right.
Microscopic fossils from Australia suggest that some bacteria evolved structures for oxygen-producing photosynthesis by 1.78 billion years ago.
The reptiles’ horns could help or hinder during foraging, depending on how they hunt. This might be why horns evolved in some species and not others.
This field of science looks to understand life — past and present — by studying how organisms altered their surroundings.
Modern birds are the only dinosaurs that survived an apocalyptic extinction event 66 million years ago.
Researchers rely on prehistoric tools and other artifacts to study the vast stretches of time before recorded history.
During nest building, these insects add five- and seven-sided cells in pairs. This helps their colony fit together hexagonal cells of different sizes.
Human ears don’t work well in the water. A mermaid would need marine creature features to talk to and understand her aquatic friends.
Scientists are rethinking how this extinct creature used the spiky limbs sticking out of its face to hunt.
