AI Summary
5 min readWhen Amphibians Were Earth's Main Source Of Nightmare Fuel
Imagine being told a rabbit, beaver, hamster, or "some amphibian" is chasing you. You wouldn't panic. Yet the irony is that one of these animals—amphibians—was once "by far the worst thing you could run into." Kermit's ancestors were the deadliest things around.
The Age of Amphibians
The story begins over 350 million years ago during the Carboniferous period. At that time, the supercontinent Pangea hadn't yet formed, and much of the planet's low-lying land was flooded by warm seas. The result: vast coal swamps covering huge swaths of the equatorial regions. Today swamps cover just 6% of Earth's surface; back then they accounted for much more. These swamps were peak real estate for amphibians, which had only evolved the period prior. They rapidly took over, expanding across continents and evolving at blinding speed into what is now called the Age of Amphibians.
