Devonian Tabulate Coral

February 4, 2011

A few years ago, I was working a project in northern Jefferson Co. Ky. that was in the preliminary stages of development. As such, the area had been stripped of vegetation leaving a vast field of regolith that was a mud pit when it rained… sticky clayey mud. But, those rains also uncovered thousands of silicified fossils that littered the ground of the project.

One of the larger pieces that I picked up was a head of the tabulate coral Alveolites. It was fossilized as silica replacement that is common of many fossils in the Jeffersonville Limestone.

The individual corallites are about 2mm diameter.
