Survival Secrets

Ancient amphibians thrived after Earth’s deadliest extinction by feasting on freshwater prey, avoiding the chaos that wiped out 90% of species.

Amphibian Ancestors

Temnospondyls, relatives of modern frogs and salamanders, dominated post-extinction waters while land predators struggled to find food.

The Tropical Dead Zone

Global warming, acid rain, and wildfires made the tropics uninhabitable—but somehow, these water-loving creatures crossed the danger zone.

Unchanged Survivors

Unlike many species that evolved rapidly after the extinction, temnospondyls kept the same body shapes and hunting strategies—and still flourished.

Size Didn’t Matter

Some temnospondyls were small insect hunters, while others were giant fish-trappers. Their diversity helped them survive in changing environments.

The Five-Million-Year Boom

Five million years after the extinction, these amphibians hit their peak—but as dinosaurs and mammals emerged, their reign began to fade.

Fossil Trail Mystery

Temnospondyl fossils in both hemispheres suggest they traveled across the deadly tropics—how they survived remains a puzzle for scientists.

Masters of Adaptation

By eating almost anything, needing little food, and hiding in shrinking water bodies, these creatures outlasted most land predators.

The Beginning of the End

Though they ruled early Triassic waters, the rise of dinosaurs and mammal ancestors signaled the slow decline of these once-mighty survivors.
