Several amphibian fossils have been found in Kentucky. They were found in Mississippian sandstones on the margin of the Western Kentucky Coal Field. One amphibian was about 5 feet long and had a long, streamlined body. It probably lived most of the time in water and ate fish and other small amphibians and reptiles. The other amphibians were smaller, but probably similar.
