But often the fossils that change our knowledge of the past are tiny and don’t carry the same visual flash as the typically-hyped finds of the giant and the fierce. Consider a tooth found in the Magnolia State.

The isolated fossil, washed out of its resting place of over 66 million years by a modern stream, was spotted by paleontologist George Phillips as he searched Mississippi’s Owl Creek Formation for fossils. The tooth was obviously from some sort of herbivorous Cretaceous dinosaur, but what kind? And so, at the intersection of the ancient and modern, Phillips posted a photo of the find to Facebook.
