Science X / When Earth went dark after Chicxulub, tiny ocean dwellers held the secret to survival

When a 10-kilometer asteroid struck Earth 66 million years ago, the planet was plunged into darkness—and about 75% of species vanished, including marine life. Now, a new study reveals that the planetary effects from the impact ...
