Plicatoria wilmingtonensis

Eocene

Castle Hayne Formation

North Carolina

These are common. I have to force myself not to bring any more home but I still manage to bring home unusually large perfect ones.

Terebratulina sp.

Eocene

Castle Hayne Formation

North Carolina

There are several species of these in the Castle Hayne. Most are very tiny but these larger ones can be found occasionally. Usually when I find one, there are several more nearby. I will go years without seeing a large one and then find several.

Oleneothyris harlani

Paleocene

North Carolina

These are the largest brachiopods found in North Carolina. The shell is very thick on one end and very thin on the other.

Terebratula maxima. In the Pliocene Red Crag of Walton on the Naze, Essex, England, they are always found as disarticulated, single shells. Most commonly the lowers. Upper valves can reach 4-5inches.

Hi Gery

Here are a few of mine. First a wide-ranging brachiopod Discinisca lugrubris (Conrad, 1843). Left: Upper Miocene, Cobham Bay Member of the Eastover Formation, Surry County, Virginia and Right: Upper Pliocene Pinecrest Sand Bed 11 of the Tamiami Formation, Sarasota County, Florida.

Very nice. The ones I find are always broken. Here are a couple from the Pliocene Yorktown Formation, Beaufort County, North Carolina.

Discinisca loeli

Miocene

Round Mountain Silt

Kern County, California

Ulysses S Grant - the grandson of the president, coauthored the paper that described this species. It is from the Shark Tooth Hill bone bed. It is a tiny brachiopod that measures 2.5 mm.

My lexicon is limited. What does tertiary mean in reference to fossils ? Something to do with the hinge process ? Nice Pics. Thanks.

Probolarina sp.

Eocene

These aren't very common. I have less than a dozen.

The Tertiary was the time between the Cretaceous and the Quaternary: 65.5million to 2.5million. It's now divided into the Paleogene (=Paleocene+Eocene+Oligocene) and Neogene (=Miocene+Pliocene).

Edit: oh my, you guys are fast. oh well, I'll leabe it up for easy reference to anyone reading.

Nice brachs all, I dont often see them from the Tertiary! I dont have any to share, my Upper Cretaceous ones are just outside the range...

I have a nice collection of brachiopods from the Pleistocene and Miocene of Japan. I just can't find them right now. That's what happens when your collection becomes too large. :wacko:
