Images of Silurian chain-coral fossils
Halysites sp. from the Louisville Limestone. Image viewed from top, with detail, and from the side. This is likely Halysites occidens, but silicification makes species identification uncertain. Specimen has been treated with acid to remove interstitial limestone. Collected from riprap in Clarksville, Indiana, and donated to KGS by Dan Phelps.
Small mound of Quepora huronensis from the Louisville Limestone. Image viewed from top, side, and in detail. Note small, mostly circular and semicircular lacunae. Collected and loaned to KGS by R. Todd Hendricks.
