Cretaceous. Bear Paw Formation. Southern Alberta, Canada. From the Devonian Period to the end of the Cretaceous, ammonites generated tens of thousands of species that invaded nearly every salt-water habitat in the world. Ammonites species came so fast and furiously that the average species only lasted a million years or less. This quick turnover means that ammonites are near-perfect paleo-clocks.
