The listing, Fossil Brachipous / Brachiopods in rock of Ordovicain Age in a rock, approx 2 3/8" x 2" has ended.

Fossil Brachipous / Brachiopods in rock of Ordovicain Age From Southwestern Ohio

The rock is approx. 2 3/8" x 2"

It is approx. 443 - 490 million years old (definitely the oldest item I ever owned or listed ).

I acquired this as part of a cub scout badge project in the early 1960's.

Please see the pictures as part of the description. The last two pictures are example of Brachiopods that I located on the internet.

Brachiopods are marine animals that, upon first glance, look like clams. They are actually quite different from clams in their anatomy, and they are not closely related to the molluses. They are lophophorates, and are so related to the Bryozoa and Phoronida. Most species of Brachiopods went extinct during the Premo - Triassic extinction event. Although they seem rare in today's seas, they are actually fairly common. However, they often make their homes in very cold water, either in polar regions or at great depths in the ocean and thus are not often encountered. There are about 300 living spices of brachiopods.

The Ordovician period (part of the Paleozoic Era) began approx. 490 million years ago, with the end of the Cambrian, and ended around 443 million years ago with the beginning of the Silurian. The Ordovician is best know for the presence of its diverse marine invertebrates, including graptolites, trilobites, brachiopods, and the conodonts (early vertebrates).

A nice beginning or an addition to ones fossil collection.
