During the Ordovician Period, about million years ago, some cephalopods grew to be as long as 19 feet, although most were much shorter. Illustrations of Selected Ordovician fossils Anthozoans Anthozoans (an-th-oh'-zo-ans) became important members of shallow sea ecosystems during the Ordovician Period. They were ancestors of modern corals. A volcanic plume later pushed these rocks up into huge dome that gradually eroded to form Nashville's central basin, exposing these fossils from the Ordovician period. The western provinces were again flooded by ocean during the age of dinosaurs, leaving Cretaceous fossil beds in sites like Coon Creek.

In this site, you can learn about the major groups of invertebrate animals and plants that can be found as fossils in Oklahoma.
Identifing a Brachiopod can be hard, but is not impossible. You can identify a Brachiopod from the shape of it's shell, the ribs and the growth lines on the shell. Actinoconchus is recognized by it's growth lines on it's shell. 3 cm is a decent size for an Actinoconchus. They. Here is a link to a guide that will get you quite far.

You may also want volume 3, which deals with the Pleistocene Champlain Sea fossils, which are abundant at several places around Ottawa. Cladids crinoidea is recognised by it's unique large number of arms.
30 cm is a decent size for a Cladids crinoidea. The Calyx is very small and semi-circle shape. It has many arms that have a turtle shell effect. The segments are rounded and are very close together.

The exposed rocks are from the upper part of the Ordovician System, except for limited exposures of Middle Ordovician rocks along the Ohio River. Older Ordovician rocks are present in the subsurface throughout Ohio. The oldest Ordovician unit, the Knox Dolomite, began to be deposited in Late Cambrian time in a tidal-flat environment.
Ordovician Period - Ordovician Period - Invertebrates: Invertebrate life became increasingly diverse and complex through the Ordovician. Both calcareous and siliceous sponges are known; among other types, the stromatoporoids first appeared in the Ordovician.
Tabulata (platform) and rugosa corals (horn corals) also first appeared in the Ordovician, the solitary or horn corals being especially.
