Extract

In his monograph on the fauna of the Utica and Lorraine Formations of New York, Ruedemann (1925b) described a new and unusually young species of Corynoides, C. ultimus. He obtained these specimens from a thin band within the Utica Shale at a locality on Ohisa Creek (a tributary of the more well known Nowadoga Creek) in the Mohawk Valley. Like many of the graptolites from the Utica, the Corynoides ultimus specimens are vague carbon films, extensively exfoliated and difficult to study. Perhaps consequently, Ruedemann's illustrations and measurements are not entirely accurate and do not reveal sufficient detail for meaningful comparison of this taxon with other, better known species.
