The numerical calibration of the base Devonian is poorly constrained due to several factors. Few precise radioisotopic age determinations are available from late Silurian and Early Devonian, limited published data carry large error bars older analytical methodologies. Volcanic ashfalls suitable for dating occur in Lower Appalachian Basin, but have not been precisely correlated into global chronostratigraphical scheme because bio- lithostratigraphical information. Here, we report a new U-Pb...

The lower Williamson Shale at Tryon Park, Rochester, New York State is unique in the co-occurrence of Stimulograptus clintonensis (Hall), previously recorded only from middle Telychian, and Pterospathodus amorphognathoides Walliser, upper Telychian ( Cyrtograptus lapworthi Biozone higher). These two co-occurring fossils are clearly providing contradictory ages for Shale. incorporation chitinozoan data both Willowvale shales does not support unequivocally either graptolite- or...
Stromatoporoid sponges flourished throughout the Silurian Period, during Middle Devonian Epoch, and first half of Late Epoch (Frasnian Age). Their prime habitats were in shallow carbonate seas tropics sub-tropics. During Early overall geographic extent stromatoporoids, their generic diversity, declined. In parallel, abundance distribution reefs decreased drastically. Throughout there is a continuous presence stromatoporoids fossil record Europe, Asia, Australia; however, this not true for...
Students in a laboratory techniques course for preservice teachers were engaged an activity that was designed to assess their skills identifying geologic materials and model situation might be encountered by new teachers. Related activites give the practical experience obtaining specimens, labeling them storing collections.The identified this (Mr. Chalkentalk's collection) comprised large volume of mixed unlabeled samples from actual secondary earth science classroom. Following activity,...
Historically, the Helderberg Group has been an important unit including some of earliest paleontologic and stratigraphic studies in North America. Once interpreted as a series coeval facies, most formations even members are separated by disconformities regionally angular unconformities. The Green Vedder Member (new) is defined within Manlius Formation Dayville reassigned from Coeymans to Formation. name Ravena member abandoned because it coincides entirely with redefined Two new members,...
