Ova sp.

Ova sp.
Mykolaiv Sands, Fore-Carpathian Depression
Middle Miocene (16-11 Ma)
Gleboviti Locality, Roztocze Hills, Ivano-Frankivsk Oblast, Ukraine
Acquired from online, August 2023

I had previously identified these as Schizaster sp., but I realized a short while later that the larger specimen only has two large gonopores, and while the one in matrix has an incomplete apical disc, it looks as if it may have those same two large gonopores. Therefore I'll consider them Ova sp. for now, the larger one seems to have the complete lateroanal fasciole from what little I can see.

These come from the same beds that have plentiful spine-coated Echinocardium leopolitanum. One specimen has some spine preservation on the oral surface, while the other one in matrix has some spines along the anterior edge, as well as seemingly on much of the oral surface as well, based on a small crevice located in the sandstone that exposes some of them.
