Connecting the environment of the ancient past with the natural and cultural history of yesterday and today.















 

 


Geology & Fossils

A major reason for the park's existence is the Devonian fossil beds. This page focuses on the geology, fossils and collecting. The interactive brochures allow you to identify Devonian fossils of the Falls area. Our long-term goal is to create identification guides to fossils of the Falls area - ranging from Upper Ordovician to Middle Mississippian.

Collecting Fossils

Information about outcrops along road cuts that are generally well-known and frequently visited by fossil collectors. Most are reliable sources for fossils, though if you are looking for a one-of-a-kind rare specimen, here like anywhere, luck and a keen pair of eyes is necessary.

Fossil Bed Identification Guide

How do I identify fossils on the fossil beds? This page has photos of many of the fossils you can see. Others are in the Virtual Field Trip (see link on the panel to the left).

Brochures

All our on-line brochures are searchable with web search engines!

Discovering Fossils

This brochure is for visitors to use when they explore the fossil beds.

Print out this brochure to use when exploring the upper or lower fossil beds.

 

Ancient Shells-Brachiopods

What is a brachiopod? How does it differ from a clam? What Devonian brachiopods are found in the Falls area? This brochure answers all those questions and contains a list of Devonian brachiopods documented here.

 

Are Fossils Important?

How do fossils help us understand the world around us? This brochure explores that question.

 

Corals

What types of corals are found at the Falls of the Ohio? What are 'rugose' and 'tabulate' corals? What features distinguish Devonian corals? How many species of coral have been documented? Find out here!

 

Crinoids & Blastoids

Crinoids and blastoids are the dominant echinoderm found in the fossil record at the Falls of the Ohio. The bodies are relatively rare, the columns (stems) are very common. Sometimes called "Indian Beads," these are common in the upper fossil beds. This brochure describes both type of echinoderms and lists species reported in the area.

Mollusks 

The "other" ancient shells found in the Devonian rocks at the Falls include clams, snails, cephalopods, and rostroconchs. This brochure describes the various classes of mollusks and lists the species than have been described.

Patch Reef

This brochure is designed to be used standing in front of our Silurian - Devonian diorama. It explains the geological history of the Devonian patch reef - the lower fossil beds at the Falls of the Ohio.

River Pebbles

Pebbles on the river bank come in a variety of colors, hues and patterns. But where did they come from... originally? This brochure discusses the origin - sometimes thousands of miles away, sometimes within the Falls area - of the river pebbles along the river's edge.

Trilobites

Ancient bug-like arthropods, trilobites are widely distributed in the Devonian formations in the Falls area. This brochure describes trilobites and lists species found here.

Microfossils of the Salem Limestone 

Focuses on the diverse fossil fauna of the Middle Mississippian Salem Limestone. This formation stretches from Indiana south to Kentucky and west into Illinois, Missouri and Iowa. Indiana Building Stone is composed of uncountable numbers of microscopic fossils. This article describes them and lists the described species.
