A few fossils in need of IDs from Penn Dixie

But as a preliminary guess, I'd go for the rhynchonellid Camarotoechia congregata.

 

That name has been updated to Cupularostrum congregata.  A decent find from Penn Dixie in my opinion!

Thanks. 

Is there a genus of  American brachiopods that hasn't changed its name in the last decade? 

[Shamalama]

Haha. I wish there was more work on them tbh. Dinosaurs bring all the paleontologists to the yard.

Hello everyone,

I didn't want to make another topic to ID this one thing so I will add on to here,

I was going through more Penn Dixie matrix collected this summer and found this object that I am unsure about the origins of.

I have these two pictures of the piece:

Object in question is the thing between Eldredgeops pygidiums and the rugose coral.

Any help is appreciated,

Thank you

The whole thing is an enrolled, flattened Eldredgeops rana. You are looking at the underside of the cephalon, 

Nice find, Misha.

I didn't even think of that,

That's probably the biggest one I've found there.

Thank you Tim.

Hello everyone,

The shale from Penn Dixie that I have has weathered even more and exposed some nice fossils, and I am not sure about the IDs on these 3.

1. This is the largest of the bunch, and it is incomplete I am not sure if it is a bivalve or a brachiopid. Also the ruler is in Inches

 

 

2. This one is quite small and it looks very similar to some other Brachiopods I have in my collection, but I have not found ones like this from Penn Dixie.

 

 

3. This is the smallest of the bunch, I believe it may be ambocoelia but I would just like to confirm that here.

Thank you very much,

Misha.

Cephalopod

Retispira gastropod.

Horn coral,

Ambocoelia brachiopod.

Amboecelia (spelling?)brachiopod.

 

Awesome!

My first gastropod too,

What are referring to as a cephalopod?

Thank you for the IDs Tim

[Misha]

Also number 2 does have a horn coral but there is also definitely a beach shell on top of it,

I am not sure the ID for it.

[Misha]

Could 2 be something like Douvillina?

[Fossildude19]

Misha, 

 

This is what I am calling cephalopod : 

 

 

 

And your second item doesn't look like Douvillina, to me. 

Looks like the end or cross section through a Horn Coral,

Hi Misha,

 

Can you show us a more lateral angle of the coral/shell piece? A view that would look across the form parallel to the rays that are shown. I want to see if there is any shape to the fossil or just a break through a coral as Tim suggested.

I will get some more pictures of the piece to see if I can show you what I am seeing.

Also I believe that first item is actually a worm burrow, it's not very straight and does not have shell texture, I included the image to show a scale of the Retispira.

Here are some more angles that may help:

That looks like a brachiopod to me, one of the strophominids with two sizes of costae.

Thanks for the better pictures, Misha. Definitely looks more like a brachiopod.

 

Try having a look at Eoschuchertella arctostriata.

That does look like it!

Thank you for all the help Tim,

I really appreciate it.

I respectfully disagree with this ID. I feel Protodouvillina inaequistriata is a closer ID for the shell due to the size of the radii (ribs). Eoschuchertella arctostriata has much finer, and numerous ribs and is generally a larger shell. See this example from @Jeffrey P for a specimen he found in the Marcellus formation, which is a little younger than the Moscow formation at Penn Dixie.  Both species are known to exist in the Moscow formation at Penn Dixie and along the Lake Erie shoreline, according to A.W. Grabau's "Geology and Paleontology of 18 Mile Creek", pgs. 193, 198.

That's what I was thinking before I posted this on here from the research I did.

I will definitely try to compare it with other specimens.

Thank you very much, Dave. For all of your help as well, you have offered some great info and I have learned a lot from you.

Thanks Dave. I agree, Protodouvillina is a better match.

I need to get a hard copy of Grabau.  

 

Here is an image from the web.

That is a good pic of a growth series. Thank you for posting it. I need to change some of my ID names in my blog now too as I was calling them all Douvillina instead of Protodouvillina.

[Misha]

I would like to get confirmation that this new find is what I think it is. 

I believe it may be paleoneila filosa.

Thank you

Hard to see the hinge line with the close up distortion in the pic, but I'd generally agree with that ID. The posterior end (right side) has an obtuse angle to it, from what I can see, rather than rounded which is more indicative of P. filosa.  I can't tell if there is a clavicular fold to the left of the beak which would indicate it could be Nuculites oblongatus.
