Dear friends,
I need your help on identification of a fossil that I found in the Carpatho-Balkanides of Eastern Serbia. The fossil was found in a quarry of Upper Devonian turbiditic, fine to coarse grained siliciclastic sediments. Shales which bear the fossil are a top part of a complete Bouma sequence. This is maybe indication that the fossil was not transported by the turbiditic currents but was buried by sediment vertically from the water column.
Late Devonian (Fameniann) age of the sediments is based on Cyclostigma remains which are wide spread in certain levels of turbidites throughout the quarry.
It was a single piece broken in two. Basically the shape represents a concave and convex pair.
Note the dark outline following the shape. I thought it was some ichnofossil. Outlines are often found on the surfaces of shales in the quarry.
Thanks for your time and hello from Serbia!
