|Before the dinosaurs' demise, a clambake extinction?|In: Science (Washington). American Association for the Advancement of Science: New York, N.Y.. ISSN 0036-8075, more
Most researchers think the dinosaurs, many plants on land, and much of the life in the sea succumbed to a huge cosmic impact 65.5 million years ago.

The culprit in this earlier cataclysm may well have been humongous volcanic eruptions in India—the same eruptions that some researchers have credited with wiping out the dinosaurs.
