Falcatus the mysterious shark with a sickle spine
Start a discussion
About 324 million years ago, the ancient seas of North America were home to Falcatus, a small but extraordinary cartilaginous fish. Only 25–30 cm long, it was a distant relative of modern sharks — and one of the strangest of them all. Rising from its back was a long, curved spine shaped like a sickle, giving the animal a striking appearance.
With its sleek, torpedo-shaped body, Falcatus was a swift swimmer and a skilled predator. Its large eyes helped it see in dim light, while its sharp, multi-pointed teeth were perfect for catching small prey.
Scientists still debate the function of its iconic dorsal spine — defense, display, or perhaps mating. Whatever the answer, Falcatus remains one of evolution’s most fascinating marine experiments.
