from the Upper Frasnian of Poland
was described from the Upper
Frasnian (Crickites koeneni
zone) of an abandoned pitstone
Jezioro Daisy about 2 km south
of Górny Mokrzeszów
(Oberkunzendorf), Silesia,
Poland.
This form differs from other
representatives of
Receptaculites by its columellae,
which are unusually thin, and by
stellate structure which is
composed by two complexes of
brachia.
