The Cincinnati zone has yielded the various world's such a lot ample and best-preserved fossils of invertebrate animals resembling trilobites, bryozoans, brachiopods, molluscs, echinoderms, and graptolites. So recognized are the Ordovician fossils and rocks of the Cincinnati area that geologists use the time period "Cincinnatian" for strata of an analogous age in all places North the USA. This ebook synthesizes greater than a hundred and fifty years of study in this fossil treasure-trove, describing and illustrating the fossils, the lifestyles behavior of the animals represented, their groups, and residing relations, in addition to the character of the rock strata in which they're discovered and the environmental stipulations of the traditional sea.

Repeated glaciations of surprising importance happened all through this tumultuous period, and diverse eukaryotic clades independently completed multicellularity, turning into extra advanced, ample, and various at its termination.
