'Missing link' in shark evolution found

Recommended Posts

Still Waters

A 380m-year-old fossil found in Western Australia has been hailed as the "missing link" in shark evolution, revealing the marine predator has a far more sophisticated lineage than previously thought.

The fossilised skeleton, jaws and teeth, found at the Gogo formation in the Kimberley region of WA, shows the ancient shark had a small amount of bone as well as cartilage.

What magnificent news.

I am always glad when they find so much of an ancient shark....not just a few million teeth.

This is interesting. I wonder how that process started; what caused a bony fish to begin replacing its skeleton with lighter material.

maybe the need to get away from larger... meaner predators... Lighter material = more speed...
