Unusual Occurrence

The oldest known Carboniferous rugose coral fauna in the Canadian Arctic Islands was collected in the Yelverton Inlet area of northern Ellesmere Island, from Bashkirian carbonates of the lower Nansen and Otto Fiord formations. It includes the generaDibunophyllumThomson and Nicholson,LonsdaleiaMcCoy,PalaeosmiliaMilne-Edwards and Haime andTizraia? Said and Rodríguez. Such a generic assemblage is unknown elsewhere above the Serpukhovian. An upper? Bashkirian specimen ofParaheritschioidesSando, collected above the main fauna, is the oldest known representative of that genus. Faunal comparisons suggest Novaya Zemlya or northern Timan as the most likely source areas for the Yelverton Inlet fauna.

New Family

Sponges occur widespread in Permian formations in western Ellesmere Island on Fosheim, Raanes, and Bjorne Peninsulas. Scheiia tuberosa Tschernyschew and Stepanov, 1916, is described from the Assistance and Tanquary formations and is the most widely occurring sponge in the collections. Haplistion arcticum (Dunikowski, 1884), Haplistion latituba (Dunkowski, 1884), Haplistion diactinum n. sp., and Raanespongia monilis, n. gen. and n. sp., all occur in the Assistance Formation. Raanespongia monilis n. sp. is the basis of the new family Raanespongiidae which is included in the Eutaxicladina.

Potential Problems

Crinoid taxa based solely on parts of the stem lead to potential problems of synonymy and to nomenclatural instability. Many stem morphotypes appear to be vicarious, and homeomorphy may be common among even the most specialized appearing stems. The affinity of the crinoid stem 'genus' Platyplateium Moore and Jeffords to the camerate crinoid family Platycrinitidae is confirmed by its association with a Platycrinites-like calyx (Platycrinites nikondaense n.sp.). Platycrinites nikondaense from the Permian of Alaska and P. ellesmerense n. sp. from the Permian (Guadalupian) of Ellesmere Island represent species that have evolved by means of a secondary decrease in number of tegmen plates and modification of the stem from the Platycrinites type to the platyplateioid form. Platycrinites remotus Strimple and Watkins, from the Upper Carboniferous of Texas represents an earlier stage in tegminal evolution, but had probably already developed a platyplateioid stem.
