Establising a high-frequency standard reference sequence stratigraphy, sea-level curve, and biostratigraphy for Morrowan strata of the Lower Absaroka I time slice based upon the Bird Spring Formation, Arrow Canyon, Nevada
… abundant fossils, and excellent exposure, the Morrowan Arrow Canyon Bird Spring strata is recommended as a candidate standard sequence stratigraphic reference for the Morrowan portion of the Lower Absaroka I supersequence. The stratigraphic architecture of Morrowan strata in Arrow Canyon was …

Petrology and Weathering Environment of Sub-unconformity Limestone unit: The Kessler Limestone member of the Bloyd Formation, Morrowan (Pennsylvanian) Northwest Arkansas
<p>In northwest Arkansas the thin, widespread Pennsylvanian Kessler Limestone of the Bloyd Formation is exposed in numerous locations. Comparison of various exposures shows the Kessler is heterogeneous in thickness and lithology. Thickening of the Kessler occurs southward into the Arkoma Basin …

Paleozoology of cores from the Tyler Formation (Pennsylvanian) in North Dakota, U.S.A.
… Formation was determined to be of Pennsylvanian (Morrowan, Atokan, and Deamoinesian) age based on the previously reported ranges of contained taxa. Four faunal communities are recognized in the Tyler and names proposed for them are based on their dominal fos sil constituents. Progressing from the …

Mid- to Late-Paleozoic Deformation On Buck Mountain, Nevada
… in northern and central Nevada.Folds in the Morrowan-Atokan Ely Limestone are erosionally truncated and depositionally overlain by the mid-Desmoinesian Hogan Formation. The lacuna developed at this stratigraphic level is temporally consistent with a regional unconformity ("C5" of Snyder et …
