unknown in flint

[Gen. et sp. indet.]

Found on a parking lot in southern Poland. The flints in the area can be either Late Jurassic or Late Cretaceous-Paleogene in age. The most common fossils are sponges, but ichnofossils, brachiopods, bivalves, echinoids, bryozoans and dasyclads also occur. Any idea on this one?

I'm voting for lost gastropod.
