CONTRIBUTIONS TO GENERAL GEOLOGY GEOLOGICAL SURVEY BULLETIN 1111-A A description of two new /aunules from rocks of Helderberg and Schoharie age UNITED STATES GOVERNMENT PRINTING OFFICE, WASHINGTON:1960 Abstract. The Middle Devonian (Givetian) of central Kentucky is represented by a complex and somewhat enigmatic succession of sandy dolomitic limestones and chert-rich wackestones, silty dolostones, and thin dark shales belonging to the Boyle Formation and Portwood Member of the New Albany Formation. Pterygotus is a genus of giant predatory eurypterid, a group of extinct aquatic arthropods.Fossils of Pterygotus have been discovered in deposits ranging in age from Late Silurian to Late Devonian, and have been referred to several different species.Fossils have been recovered from four continents; Australia, Europe, North America and South America, which indicates that Pterygotus might have had a nearly JM Journal of Micropalaeontology JM J.

Create Six stratigraphically distinct trilobite faunas are recognized in the Lower Mississippian strata of the central United States. These faunas range in age from earliest Kinderhookian to Meramecian, and are, in ascending order: Pudoproetus missouriensis, Comptonaspis swallowi, Proetides insignis-Perexigupyge, Breviphillipsia semiteretis, Exochops portlockii, and Hesslerides bufo.Trilobite species diversity waxed Lower Devonian faunas of the Urals and Kazakhstan showed some important differences, probably due to community control.

On conodonts from the Chazy and Cincinnati group of the Hamilton and Genesee-shale Hey, @Fruitbat I absolutely love your library, and I'm aware of the amount of effort that must be put into it. I have just one comment though, I'm a tad surprised that there aren't many Everhart papers on the SHC (in the KS Cretaceous section) - but no worries I'm sure you have your reasons. Once again, thank you so much for putting in place, it is absolutely fantastic.

Turbidity currents, tectonism, debris flows, glaciation, and other geologic processes are considered to be responsible for the generation of Silurian Mississippian diamictites i Shared features of these faunas P.
