Missourian Posted March 27, 2013 Share Posted March 27, 2013 (edited) Goniatites are ammonoids that range from Devonian through Permian. These beautiful fossils seem to have an endless variety of form and detail. I can't get enough of them. They are frustratingly rare in my parts, so anyone who has any, please show 'em. I'll start with a few that I've posted in other threads.... Glaphyrites sp. or Eoasianites sp. Muncie Creek Shale, Pennsylvanian Johnson County, Kansas Glaphyrites sp. (or something else?) (~2 mm juvenile) Winterset Limestone, Pennsylvanian Jackson County, Missouri Subkargalites sp. (1 cm) Winterset Limestone, Pennsylvanian Jackson County, Missouri Schistoceras sp. Muncie Creek shale, Pennsylvanian Kansas City metro Edited April 3, 2013 by Missourian Context is critical. Link to comment Share on other sites More sharing options...
nils Posted March 27, 2013 Share Posted March 27, 2013 Nice fossils! Here are some of mine.. Cheiloceras sp., Famenne, Upper Devonian Bergisch-Gladbach, NW Germany. Size of specimen is about 2 cm. Goniatite Tornoceras sp., Famenne, Upper Devonian Bergisch-Gladbach, NW Germany. Size of specimen is about 15 mm Goniatite Manticoceras sp., Frasne, Upper Devonian Wallersheim, NW Germany. Size is about 2,5 cm. Cheers, Nils Link to comment Share on other sites More sharing options...

Missourian Posted March 28, 2013 Author Share Posted March 28, 2013 (edited) Prouddenites sp. Muncie Creek Shale, Pennsylvanian Kansas City metro Even though this ammonoid belongs to the order Prolecanitida rather than order Goniatida, I think they can still be called goniatites.

JimB88 Posted March 28, 2013 Share Posted March 28, 2013 Those are cool! Those in a nodule of some kind? What is the blue material in that Schistoceras from your first post? I would love to find some that big. Link to comment Share on other sites More sharing options...

I would love to find some that big. The Muncie Creek specimens are in phosphatic concretions, except for the sectioned Glaphyrites. I'm not sure why the Schistoceras is blue. Other fossils, such as fish spines, can have the same color. Context is critical. Link to comment Share on other sites More sharing options...

Ludwigia Posted March 28, 2013 Share Posted March 28, 2013 I don't have many, but I'll show what I've got. The first ones are the same species as Nils' first one - not quite as pretty, but ok for samples. All of the below are pyritized. Cheiloceras sp. Brilon-Nehden, Germany. Nehdenites sp. from the same site as above. Tornoceras arkonense Hungry Hollow, On. Canada. Greetings from the Lake of Constance.

Missourian Posted March 29, 2013 Author Share Posted March 29, 2013 Thanks everyone for the beautiful examples so far. Steve, you'll go through a thousand-plus MC concretions (and probably go insane) before an ammonoid shows up. Context is critical. Link to comment Share on other sites More sharing options...
Bullsnake Posted March 29, 2013 Share Posted March 29, 2013 (edited) ...Steve, you'll go through a thousand-plus MC concretions (and probably go insane) before an ammonoid shows up. Alright, 3 things: (a.) I'm still gonna look (2.) I might already be insane (c.) PetrolPete came through with the nodules he gifted Here is my first Goniatite! Now it's time to buckle down and start practicing my prepping techniques so I can get it extracted. Scary! Pennsylvanian-Des Moinesian ~Senora/Fort Scott fm. Undetermined sp.

Missourian Posted March 29, 2013 Author Share Posted March 29, 2013 Steve, are there any other spots where the sutures are visible? Context is critical. Link to comment Share on other sites More sharing options...
Bullsnake Posted March 30, 2013 Share Posted March 30, 2013 (edited) Steve, are there any other spots where the sutures are visible? No. There is that outer layer that looks really thick, and at points appears to be melded with the concretion. I honestly want to get some prepping practice under my belt before attempting to go any further trying to extract this.

PetrolPete Posted March 30, 2013 Share Posted March 30, 2013 (edited) I have a couple all are from: Pennsylvanian-Des Moinesian [Probably] Little Osage shale: Fort Scott formation (if not then probably Excello shale: Senora Formation) Found Near Lake Oolagah Oklahoma (sorry I'm unsure on most ID's, its been difficult to find pictures to compare to) Partial Undetermined: Undetermined: Undetermined: [Possibly] Glaphyrites: Partial Undetermined: Undetermined: Undetermined (might actually be a nautaloid, but it's hard to tell): Edited March 30, 2013 by PetrolPete Link to comment Share on other sites More sharing options...

Missourian Posted April 2, 2013 Author Share Posted April 2, 2013 Somoholites sp. Liberty Memorial Formation, Pennsylvanian Kansas City metro I think I have the correct ID. It is similar to a couple other forms, but it has the spade-like lobes that are characteristic of Somoholites. Context is critical. Link to comment Share on other sites More sharing options...
taj Posted April 2, 2013 Share Posted April 2, 2013 (edited) a few pics from my shelves( low quality , but cannot find the time to do better, kids are driving us nuts with this long winter...) Some permian stuff from TImor(not prepped yet) Metalegoceras sp agathiceras sp then some stuff from Russia , permian popanoceras annae (south Ural) and frasnian( Northern Ural, Uchta River) Manticoceras lyaiolense And then a bunch of devonian bugs I collected in Morocco 2 years ago : I still have to sort, prep, and identify them( probably a mix of goniatits and clymeniids) This plate shows some potential .

By 'low quality', I take that you are referring to the photos and not the specimens , because those are beautiful. Also, it's not fair that ammonoids are so rare in the Carboniferous but much more common in other periods. Edited April 2, 2013 by Missourian Context is critical.

Missourian Posted April 3, 2013 Author Share Posted April 3, 2013 I 'borrowed' this from one of JeepDigger's posts: Gonioloboceras sp. Farley Limestone, Pennsylvanian Johnson County, Kansas It is the first goniatite I've seen in the Farley. Context is critical. Link to comment Share on other sites More sharing options...
Missourian Posted April 3, 2013 Author Share Posted April 3, 2013 Preshumardites sp. Muncie Creek Shale, Pennsylvanian Johnson County, Kansas I traced the sutures because they were otherwise very difficult to make out. I'm still happy with the results, but I wouldn't do it today.
