Suborder Amplexoporina Astrova, 1965 Family Atactotoechidae Duncan, 1939

Atactotoechus polygonius Bigey, 1988 ( Fig. 4D, E ).—Four zoaria were gathered from the upper Givetian Laskowa Góra Beds at Laskowa Quarry. Similar atactotoechid is identified in the thin section from possibly correlative Stringocephalus Beds at Sowie Górki. The species was described from the middle Frasnian Beaulieu Formation of Ferques ( Bigey 1988a, b).

Leptotrypa sp. —Undeterminable representatives of this common trepostome genus are found in several Givetian localities: Laskowa Góra, Górno (set A) and Jurkowice−Budy (set E). Fragmentary specimens from Górno and Jurkowice−Budy show affinities to L.? crassa Bigey, 1988 , described from the Givetian/Frasnian passage (Cambreséque Mbr. of the Beaulieu Fm.) at Ferques ( Bigey 1988a).
