Whats Your Favorite Brachiopod?

Recommended Posts

My favorite would be the Mucrospirifer sp that I have found for years in WVA. I do not have any pics of the ones I have and those are packed away.

As for slabs, I have several that are in my front yard. These are from KY and I lost the paper that I wrote the formation and stuff on. I really need to get that info again. LOL :

Next, also from KY is a small grouping where the brachs have actually become geodes:

I like the one with calcite and dolomite crystals. Thanks B)

Many times I've wondered how much there is to know.

Piranha,

Yes, I am very proud of that brachiopod as well as all my other Glass Mountain material. That stuff is very fragile. I have it stored in cotton lined boxes and I don't handle them except with extreme care. I origionally thought that silicified fossils would be pretty tough but the degree of silicification is pretty thin in most of my stuff. You can crush the fossils to powder between your fingers with little effort.

Check out this Productid brachiopod.

WoW, I collect specimen seashells also and this brach reminds me of a Star-Shell. The ANGARIA sp.(a marine gastropod) have thin spines on their shells and there not so much for protection but to help promote the growth of algae, sponges, and other critters for camouflage. When you are acid cleaning them do you find other silicified fossils like bryozoans on them?

mikey, I have aton of pop outs that I collected that I am soooooo tempted to try and split to see what goodies are inside. Just not sure the best way to go aboutit.

stunning examples, jkfoam, and I also enjoy collecting the geodized brachs, very nice smokeriderdon :)

i have been cutting a few on the wet saw, most of the intact ones arent too interesting inside, they seem to need to have a hole or be cracked to help the process along

My favorite group of brachiopods has always been the silicified brachiopods from the Permian formations of the Glass Mountains in Brewster County, Texas. I was fortunate in having been able to collect there back in the 1970's. I took out several limestone chunks that I was able to dissolve in acid and recover the silicified fossils.

......

This particular brachiopod is identified as Hercosestria cribrosa Cooper and Grant, 1969. Its picture is shown below. Its Order is Strophomenida the SubOrder is Productidina.

Excellent. It could be called a Tiffany lamp shell. :)

I'm stumped, so tell me, 'whats my favorite brachiopod?' ;) I been thinkin' bout this since you started this thread and I can't make the call. It really is a tough decision considering the choices and the fact that I am pretty certain I have not yet seen every genus there is!

;) Just for kicks, take a look at this list http://en.wikipedia....achiopod_genera It took a few seconds to load on my ol' computer ;)

Okay, given I really cannot choose, I will say today my favorite one was this one my grandaughter found! She declared and named it...

"Squushed flat seashell" sp

I guess I would have to say I like whichever one I happen to find

but I do like the enteletes,

and these are fun to find because they are big!

Pennsylvanian, Brachiopod Productid, echineria

The one on the left has some really soft purple

coloring in spots but it doesn't show real well in the photo. Any dispute or confirmation on ID would be appreciated ;)

and the jurasania are interesting :)

Nice one Missourian! I have found a few examples but none with both wingtips intact! The nicest unbroken neospirifers I have found remain 'in situ' ;) There is a large exceptional example in this boulder post-7046-0-29889200-1325883325_thumb.jpg a neospirifer with very long wings!

And here are some different brachs I have posted in the last 6 months!

post-7046-0-63781500-1327636937_thumb.jpgI think these are meekella but not 100% certain, any thoughts?

Hello,

One day, I received Brachiopods during an exchange and in the package, one was broken....but we can see the "Brachidium" who hold the lophophore...

Postepithyris cincta, Upper Oxfordian, Bourges, France

For one time...thanks for the "rough handler" of the french national post company!!!

;)

It's also cool how you can see how the sediment seeped in and pooled in the bottom half.

This brachiopod cluster is from the Silica Shale of Ohio. I saw it for sale at MAPS and had to have it. A lot of encrusted Paraspirifer have been illustrated but I have never seen anything as spectacular as this specimen. When I got back from MAPS, I posted it on the forum. Since then I cleaned a lot of the encrusting shale and now the pyritized brachs look a lot better. This amazing specimen is an example of encrusting organisms and what can be learned from them. There are 12 Orthospirifer attached to the Paraspirifer. The cluster of Orthospifer show how the Paraspifer was in life position in the mud with the pedical down and the commissure up. As the Othorspifers attached to the shell and grew, they eventually covered the commissure preventing the Paraspirifer from opening its valves and probably killed it. The Othospirifer were then encrusted by bryozoans and worn tubes.

Thank you for posting that amazing brach cluster Gerry. Its not only a cool thing to look at, it also comes with a great story from the Devonian.

Those are awesome Herb!

Do you know what age they are and where they were collected?

I just got this specimen and wanted to add it to my thread. Its my new fav and its very similar to the specimen my buddy Gerald posted. Like Gerald's brach cluster, I think these spirifers were attached to the one Paraspirifer in the middle of this cluster.

My favorites are the nice assemblages where you really get a feel for the environment the came from. This set is a group of Onniella from Kentucky.
