The limestone at the Falls of the
Ohio is composed of skeletal remains from countless numbers
of corals, stromatoporoid sponges, echinoderms, brachiopods,
mollusks, arthropods, and microscopic organisms.
It is called the Jeffersonville Limestone
(after the city of Jeffersonville which was originally at the
upper end of the Falls) and dates from the latest Early Devonian to Middle Devonian. (Geologists
call this Emsian and Eifelian Age - 390 to about 380 million
years ago). |
