Around 66 million years ago, a cataclysmic asteroid struck Earth, marking the end of the Cretaceous period and bringing about a mass extinction event that wiped out roughly 70% of life on the planet.

A species of clam is back from the dead. Known as Cymatioa cooki, the clam had only ever been found as a fossil, and scientists presumed that the species had been extinct for more than 40,000 years.

Newly discovered kelp fossils peg their existence to 32 million years ago. These fossils may help explain how the Pacific Ocean's underwater 'forests' came to be. The kelp forests that hug the Pacific ...

A new paleontology study by UChicago researchers discovered that rock-boring clams, known as bivalves, vary in shape despite performing the same function. This paper is one of the first major studies ...

About 66 million years ago – perhaps on a downright unlucky day in May – an asteroid smashed into our planet. Even groups that weathered the catastrophe, such as mammals, fishes and flowering plants, ...
