How To Make A Fossil Collection
People who live in the Cincinnati area are very lucky with respect to fossils. The rock of the area is abundantly supplied with well preserved fossils, and, because of the many hillsides, the rocks containing the fossils are well exposed. The great abundance of beautifully preserved fossils sometimes is bad for local collectors. They become so used to finding essentially perfect specimens that they ignore fossils that aren't complete and fully eroded from the rock. That's really sad, because...

Fossil Croups Of Minor Importance To Beginners
The phylum Porifera includes the sponges. The name means hole bearing, a reference to the system of holes and canals whereby the animal circulates water through itself. Sponges are primitive creatures. They are multicellular, but the cells are not organized into tissues. Members of the phylum are characterized by specialized cells which cause water to flow through the animal by means of beats of whip-like structures termed flagella sing., flagellum . Many sponges have hard parts composed of...
Preface To The Present Edition
This is basically a reprint of the 1 985 edition of this work. However, taxonomic revisions that have been made since then are noted. In addition, some errors, typographic and otherwise, have been corrected. William I. Ausich and Loren E. Babcock of the Ohio State University, Richard D. Hoare of Bowling Green State University, and Michael R. Sandy of the University of Dayton very kindly offered advice on taxonomic questions. I am grateful for their help. The rock in the Cincinnati region 7...

Those on the right are names that have been applied to rocks in the Ohio, Kentucky, and Indiana area. The different names do not necessarily represent different rock units nor their lateral relationships. See page 14.

Fossils Found In Various Richmondian Formations
Homotrypa wortheni. Bryozoan. Externally resembles those Par-vohallopora with sharp, high monticules. Fig. 1, enlarged. Fig. 3, tangental thin-section showing numerous small acanthopores and practically no mesopores. Fig. 4, longitudinal thin-section showing cystiphragms limited to the outward-curved mature part of the zooecia. Whitewater. Retrosirostra carleyi. Articulate brachiopod. This species is easily distinguished by the outward slant of the in-terarea of the pedicle valve. Limited to a...
Cincinnatian Environmental Conditions
The sediments of the Cincinnatian Series were deposited in a shallow, marine sea which covered much of North America in late Or-dovician times. All of the major fossil groups known in Cincinnatian rocks which have survived to the present are exclusively marine or have marine representatives. Most of these animals lived on or near the bottom. Few bottom dwelling animals in the modern seas live below 180m 600 ft. deep, the maximum depth to which light penetrates. Some of the rocks found in the...

The Cincinnatian Formations And Where To Find Them
CYNTHIANA G ROUP These are the middle Ordovician rocks which underlie the Cincin-natian in our area. Near Cynthiana, Kentucky, the group consists of limestones and shales. To the north these change to the massive Point Pleasant Limestone, which is exposed near Moscow, Ohio. The lowest unit of the type-Cynthiana is the Greendale Limestone it contains many fossils similar to those found in the lower Maysville Group. Collecting The Greendale is well exposed near Cynthiana, Kentucky, in stone...

Summary Of Fossil Croups Found In The Cincinnatian
horizons are bryozoans. However, substitute index fossils usually serve adequately for the purpose. Bryozoa, or moss-animals, are perhaps the most common fossils in the local rocks. They are known from the Late Cambrian to the present, and, although exclusively aquatic, inhabit both fresh and marine waters. Specimens collected in this area have the appearance of twigs, branches, flattened un-symmetrical masses, or crusts on shells or other bryozoans. What is found is actually a colony zoarium...
