In 1938, a large, ugly fish—the likes of which no scientist had ever seen—was found near the island of Madagascar.
For fins it had fleshy stumps on which it could actually walk. It had a powerful jaw and square teeth. But the most astounding discovery was that this fish was a coelacanth.
The coelacanth first lived in the Devonian period. This contemporary descendant was almost identical to its ancestor, not changing significantly in 345 million years!
Before 1938, biologists had believed that the coelacanth became extinct like the dinosaurs.
