Book Description
A recent renaissance in the field of "event" stratigraphy has promoted a much more thorough examination of the geologic record of particular fossil-bearing strata. This reference work compiles the findings of leading researchers on fossil beds, epiboles and global bioevents, mapping out a definitive temporal and regional classification of event horizons. Based primarily on research with Lower and Middle Paleozoic rocks of eastern North America, 'this volume significantly links these events to relatively short-term phenomena, including storms and climate-forcing cycles. An invaluable resource for specialists and students in the fields of paleontology, paleoecology, stratigraphy, and sedimentology, Paleontological Events helps to clarify the biological and taphonomic significance of these horizons.

Book Description
Mestognathus, an important Early Carboniferous conodont genus whose appearance has generally been thought to coincide with, and define, the base of the Visean, evolved from Clydagnathus during the Tournaisian and ranges from that stage into the Namurian. Five species, including M. harmalai sp. nov. and M. praebeckmanni sp. nov. , are distinguished by the gradual phyletic development of the parapet, the fixed blade, the anterior notch, the position of the carinal deflection, and the increasing tendency to evert the basal cavity. Mestognathus dhuensis and M. neddensis are demonstrated to be synonyms of M. beckmanni, M. bipluti, or Mestognathus spp.
