Two New Crinoids from Lower Mississippian Rocks in Southeastern Kentucky
TWO NEW CRINOIDS FROM LOWER MISSISSIPPIAN ROCKS IN SOUTHEASTERN KENTUCKY BY GEORGE M. EHLERS AND ROBERT V.

EHLERS AKD ROBERT V. ICESLING Museum of Paleontology, The University of Michigan .~BsTR.~~T-AII~~~~specimens collected many years ago bl- the senior author and his students near Mill Springs, Kentucky, are a new species of Agaricocrinzis and a new speries of Actino- crinites. Although only one specimen of each is known, it is well preserved. The new Agnrico- crinus bears a resemblance to A. ponderoszts Wood, and the new Actinocriniles to four species described by Miller & Gurley: A. spergenensis, A. botuztosz~s,A. gibsoni, and A. shnronensis. A preliminary survey of species assigned to Agaricocrinz~ssuggests that revision of the genus is overdue. Although the occurrence of the specimens leaves some doubt as to their stratigraphic posi- tion, we conclude that they both probably weathered from the Fort Payne formation and rolled down the slope onto the New Providence, where they were found. The sites where the crinoids were picked up are now deeply inundated by water impounded by the Wolf Creek dam on the Cumberland River. INTRODUCTION onto the New Providence, \$here they were OTH of the new crinoids described here are found. rZt present, both the New Providence B from Lower Mississippian rocks in the valley formation and the I~asalbeds of the Fort Payne of the Cumberland River in Wayne and Russell are underwater at the type locality of the new Counties, Kentucky. -

G. SABLE, R. C. KEPFERLE, and W. L. PETERSON ABSTRACT The Harrodsburg Limestone (Mississippian) in northwest-central Kentucky consists of 20 to 50 feet of light-gray coarse-grained fossil-fragmental limestone and minor silty limestone. It underlies the Salem Limestone, overlies the Borden Formation, and includes the Leesville and Guthrie Creek Members, of the Lower Harrodsburg of P. B. Stockdale and the Harrodsburg (restricted) as used by him. INTRODUCTION The name Harrodsburg Limestone was given (Hopkins and Sieben- tlial, 1897) to a unit of predominantly carbonate rocks of Mississippian age in Indiana and was subsequently used in Kentucky. -
Columnals (PDF)
2248 22482 2 4 V. INDEX OF COLUMNALS 8 Remarks: In this section the stratigraphic range given under the genus is the compiled range of all named species based solely on columnals assigned to the genus. It should be noted that this range may and often differs considerably from the range given under the same genus in Section I, because that range is based on species identified on cups or crowns. All other abbreviations and format follow that of Section I. Generic names followed by the type species are based on columnals. Genera, not followed by the type species, are based on cups and crowns as given in Section I. There are a number of unlisted columnal taxa from the literature that are indexed as genera recognized on cups and crowns. Bassler and Moodey (1943) did not index columnal taxa that were not new names or identified genera with the species unnamed. I have included some of the omissions of Bassler and Moodey, but have not made a search of the extensive literature specifically for the omitted citations because of time constraints. Many of these unlisted taxa are illustrated in the early state surveys of the eastern and central United States. Many of the columnal species assigned to genera based on cups or crowns are incorrect assignments. An uncertain, but significant, number of the columnal genera are synonyms of other columnal genera as they are based on different parts of the stem of a single taxon. Also a number of the columnal genera are synonyms of genera based on cups and crowns as they come from more distal parts of the stem not currently known to be associated with the cup or crown. -
A High Resolution Palynozonation for the Pennsylvanian to Lower Permian

Issam Al Barram, XGL/3X, Petroleum Development Oman LLC, P.O. Box 100, Muscat Post Code 113, Sultanate of Oman. Email: [email protected] Key words: Al Khlata Formation, Pennsylvanian, Lower Permian, Palynology, High Resolution Biozonation, Gondwana Correlation. ABSTRACT Palynology is the main method of correlating the subsurface glaciogenic Al Khlata Formation of Oman, due to extreme lateral variability of facies, and poor seismic resolution. The chief 1 operating company in Oman, Petroleum Development Oman, has developed a robust in-house palynozonation through almost 40 years of exploration and production based on thousands of samples and hundreds of well sections. In this paper the formal definitions of the biozones are published, and the biozones are correlated in detail with faunally-calibrated palynological biozones in Western Australia, thereby allowing correlation with the standard Russian stages. Seven biozones are distinguished. The oldest, biozones 2159A and B, of probable late Pennsylvanian age, are characterised by low diversity assemblages of Punctatisporites and monosaccate pollen, with Biozone 2159A having a lower proportion of monosaccate pollen than Biozone 2159B. Biozone 2165A, of probable Asselian age, is characterised by common cingulicamerate spores and Microbaculispora Group; while Biozone 2165B contains in addition to the above, common Horriditriletes Group, and is likely to be Asselian-Sakmarian in age. -

González, Department of Geology, The University of Kansas, Lawrence, KS Robert L. Brenner, Department of Geoscience, The University of Iowa, Iowa City, IA Abstract The Cretaceous Dakota Formation in the areas of Kansas, Nebraska, and Iowa contains a rich and well-preserved microfl ora of fossil palynomorphs. A comprehensive listing of these taxa is presented in this publication as part of a continuing effort to develop a refi ned biostratigraphic scheme for mid-Cretaceous terrestrial deposits in North America. The Dakota Formation in this region contains four distinctive Albian–Cenomanian palynostratigraphic zones that are used to partition the unit into successive depositional cycles, and each zone records deposition in fl uvial-estuarine environments. The late Albian Kiowa–Skull Creek depositional cycle at the base of the Dakota Formation is recognized throughout the study area, and is also recognized in other parts of the Cretaceous North American Western Interior basin. The overlying newly recognized latest Albian “Muddy–Mowry Cycle” is formally defi ned for the fi rst time in this paper and correlates with depositional cycles recognized by other workers in other parts of the Western Interior basin. -

ABSTRACT- The succession cropping out in the Fosso Pantanelle area (Mt. S. Giovanni, Calabrian "Catena Costiera'; Upper Trias) provided a rich and well preserved conodont fauna. The basin stratigraphic succession is characterized by cherty lime mudstone with minor fine- grained calciturbidites and suspected tujìtes. Conodont founa is dominated by M. hernsteini and M. posthernsteini in the lower and middle part of the section, and by M. uftima in the uppermost part. Every species is represented by a great number of specimens. On the basis of the chronostratigraphic classification ofKozur & Mock (1991), the whole section may be referred to Rhaetian. Due to the good preservation and the great abundance of conodonts (some occurring in clusters), the calabrian Catena Costiera succession may represent a reference succession for the study ofthe latest Triassic conodont founas and chronostratigraphy.
