Tarrasius

Coming soon

The appearance of tetrapod-like spinal organization in a ray-finned fish shatters the presumed relationship between complex vertebral anatomy and both walking and terrestriality. The eel-like Tarrasius possessed no hind fins and a long dorsal fin, indicating it used it's surprisingly intricate spinal column for swimming, not walking.

And while Tarrasius lived several million years after the first tetrapods with hands and feet, the discovery of these spinal features in a fish species confirms that this anatomy can evolve separate from the evolution of walking behavior.

Tarrasius tends to swim in schools or solidarity.

During the Carboniferous epoch, which lasted between 359 million and 318 million years ago, Tarrasius lived in shallow bodies of water in what is now Scotland. It was once believed that Tarrasius had a simple vertebral column made up of body and tail segments, similar to many fish. The spine morphology of this fish is similar to that of humans and has been discovered in the fossilized aquatic eels.
