An articulated polychaete jaw apparatus from the Carboniferous Kittanning Formation, western Pennsylvania, U.S.A.

  • G. Kent Colbath


An articulated polychaete maxillary apparatus recovered from a bedding plane exposure in the Carboniferous Kittanning Formation of western Pennsylvania is described. The specimen exhibits a number of characters in common with modern members of the family Eunicidae, but differs in lacking the interlocking ridge and furrow system on the bases of the first maxillary elements, and particularly in the absence of jaw calcification which characterizes modern eunicids. The new genusBrochosogenys is erected to incorporate this species (Brochosogenys bipunctus n. sp.) and 2 additional species previously described from the Carboniferous-Lower Permian:B. siciliensis (Corradini & Olivieri 1974) n. comb. (genotype) andB. reidiae (Hinde 1896) n. comb.

Aus der oberkarbonen Kittanning Formation (oberes Westfal) von Pennsylvania, USA, wird der Kieferapparat eines Euniciden,Brochosogenys bipunctus n. gen. n. sp. (Annelida, Polychaeta), beschrieben. Er zeigt zahlreiche Übereinstimmungen mit den Kieferapparaten moderner Vertreter, wenngleich er nicht wie diese verkalkt ist. Zur neuen Gattung werden zwei weitere aus dem Karbon und unterem Perm beschriebene Arten gestellt:B. siciliensis (Corradini & Olivieri 1974) undB. reidiae (Hinde 1896).
