Description:Excerpt from Memoirs of the New York State Museum, Vol. 1: The Development of Some Silurian Brachiopoda The occurrence in such great numbers of immature shells in these deposits may be explained by the luxuriant fauna which ourished in this Niagara basin, by the quiet seas of this region and by the rapid sedimenta tion of the shales. The richness of the material is shown by the great profusion of specimens representing the sponges, corals, crinoids, bryozoa, brachiopods, gastropods, annelids and crustaceans, comprising altogether about one hundred and fifty species. The lamellibranchs and cephalopods were also doubtless abundant, but the conditions existing for the preserva tion of their remains were not favorable, probably on account of the com position of their shells, and but sixteen species have been noted. That the fauna was protected from excessive storms and the action of sea currents, is evinced by the usual perfection of the fossils. Some of the crinoids are unbroken and remain attached by their roots, retaining their arms in place also, large colonies of delicate branching corals and bryozoa still preserve their unity. The specimens were rapidly buried in the soft calcareous mud and show none of the eroding or disintegrating action of the water, such as would have been produced had they lain for any considerable period unprotected on the sea bottom. It is true that many specimens are incrusted with bryozoa, annelids, cranias and other fixed and incrusting forms, but the majority of these seem to have flourished during the life of their hosts.
