I am attaching photos of Sigillaria fossils in my collection. Members of the Forum have been helpful before and as always, suggestions/comments/corrections are welcome. The first image is of a Pennsylvanian Sigillaria syringodendron specimen from Czechoslovakia. The second image is of a Sigillaria specimen from the Pennsylvanian in Eastern Kentucky. The third image is a Pennsylavanian Sigillaria specimen from the Westphalian in Czerwionka, Poland. The fourth image is of Pennsylvanian Sigillaria leaves from Podrovskoe, District of Donetsk Region, Ukraine. The contrast is poor but these leaves do have a remarkable similarity to grasses (although grasses did not evolve until hundreds of millions of year later). The last image is of a Pennsylvanian specimen from Kentucky that was identified by a helpful Forum member as a Sigillaria cortex specimen.

I want to submit for identification the specimen below. It came from the Carboniferous of Leon, Spain, labeled as tree trunk cortex. There are no other informations available. Any thought of what might be exactly, or a more precise ID will be welcomed. Thank you.
