Sediments recovered from Hole 918D on the continental rise of the Greenland Margin were found to contain siliceous sponge spicules, silicoflagellates, and ebridians. A large fossil-barren interval occurred in early Miocene and late Miocene sediments of the core, with sponge spicules occurring in the middle Miocene. Though generally rare, the sponge spicules were morphologically diverse, with monaxons being the most abundant. Other morphologies and an undescribed spicule type were found. Representatives of several silicoflagelate genera were found in a narrow horizon of the upper Pliocene. The silicoflagellates were of a variety of ages showing that this layer has been reworked. This interval also included two large ebridians, Triskelion gorgon and Adonnadonna primadonna, that have not been previously described from the North Atlantic.
