Platypterygius (Myopterygius) kiprijanoffi (Romer).
Matrix free prefect paddle bone from an Ichthyosaur. All faces intact. Nice preservation and detail. The Kursk 'Osteolite' deposit is the direct equivalent of the English Cambridge Greensand . Both deposits share a common vertebrate fauna. Right in the war zone on the Russian / Ukrainian border so this material now impossible to obtain.
