Ordovician Unknown

On my Sunday exploration, I came across a cliff that exposed something I had never seen before. These specimens were in a very narrow band (4 inches thick) and the hard limestone reminded me of Maquoketa as opposed to Galena.  They have a spongish look to it but they also remind me of a recepticulite, similar to Tetragonis sulcata.   I forgot my size marker. These are about thumb size if you have short stubby thumbs like me!!

Interesting! How many of them did you find, just these or are there more?

@piranha, here is an rough example of Ischadites iowensis that I found that same day. This is the classical look for this area. A big ol donut. The unknown specimens have no resemblance. They look like little  "thumbs".  That is why I was guessing Tetragonis sulcata. Your thoughts???

@Wrangellian, There were 7 in the piece of rock that I brought home about 12 by 6 by 4  inches in size.

Here is another Ischadites iowensis with similar features in cross-section.

 

The only info I found on Tetragonis sulcata is from European-Baltic-Scandinavian examples.  Other than that ... I have no idea:shrug:

It's funny that that link would say Ischadites is reportedly only found in Oklahoma, and shows a specimen of I. iowensis!   :zzzzscratchchin:

Sometimes the state was part of the other's territory at the time, but it doesn't seem likely in this case.

Here are a few more pictures of the unknown Fisherites/ Recepticulites showing their shape after a bit of cleaning. Again, they are taller than they are wide. The other fisherites, including   Ischadites iowensis are much wider than they are tall.

  Here is an example of  Ischadites iowensis posted by our departed Caleb found in the area I hunt. It is flat, more like a pancake

Research on these specimens has been unrewarding. Any time I find something that may be helpful, it is not available to the public without a hefty price. So if anyone knows who I may be able to ID this through, PLEASE let me know.

 @piranha, I didn't thank you yet for your help/assistance on both my trilobite post and fisherite post. So  now let me  say how grateful I am!

 As a sidenote, here is one specimen that fractured revealing a crystalized center!! Unless it signifies a hollow interior??? Doesn't help much with ID, but there are members that appreciate the beauty of these finds.

I do need to finish extracting it from the matrix
