Carboniferous Roachoid? Westphalian A Zaleskie Beds Poland

[EliasG]

Hello!

In the past couple months I have been searching out terrestrial arthropod fossils of the carboniferous. In this time I have procured quite a few specimens that I would love to have examined by members of the community, especially those experienced in the identification of carboniferous fauna. I will post the specimens one by one over the next week, if they turn out to be something different than the name they were sold by I will not be disappointed. My experience in Entomology and close disciplines such as Arachnology and Myriapodology has only been with modern species, excluding minor experience with arachnids in amber, so I am so excited to pick your brains!

 

The first fossil was indicated as being from the Carboniferous Zaleskie Beds of Poland, dated at 314 mya. It was sold to me as a "roach" though I know roaches had yet evolve so if so i'm guessing this would be a roachoid. The fossil itself is 3.0 x 2.5 x 1 cm. I will be posting pictures of the specimen below, please let me know if you have any questions or need further information to support a conclusive ID.

 

Thank you all so much for your help! Looking forward to your input.

I would say that there is not enough preserved to claim that is a roach. You should ask the seller for evidence.

This looks similar to coprolite material from Mazon  Creek area. Not seeing roach here.

Looks very much like Achistrum sp., a Mazon Creek sea cucumber.
