Polished slab of an unidentified coral from the northern Kainach Gosau, just a small boulder in an area with a thin bed of rudist-coral-limestone amongst all the conglomerates and sandstones. Matrix of this coral is quite sandy, too.  Note the very sharp and well preserved costae (ribs). Any hints to its ID ? Thanks!
