  • Two New Crinoids from Lower Mississippian Rocks in Southeastern Kentucky

    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. KESLING Reprinted from JOURNAL OF PALEONTOLOGY Val. 37, No. 5, September, 1963 JOURNALOF PALEONTOLOGY,V. 37, NO. 5, P. 1028-1041, PLS. 133,134, 3 TEXT-FIGS., SEPTEMBER,1963 TWO NEW CRINOIDS FROM L20\'C7ERMISSISSIPPIAN ROCKS IN SOUTHEASTERN KENTUCKY GEORGE M. 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.

    Geology and Why it Matters This story was made with Esri's Story Map Journal. Read the interactive version on the web at http://arcg.is/qrG8W. The geology, landforms and land features are extremely important components of watersheds. They influence water quality, hydrology and watershed resiliency. Every watershed has critical areas where water interacts with and mobilizes contaminants, including non-point and point source contributions to surface water bodies. Where and how nutrients, bacteria and/or pesticides are mobilized to reach surface water can be better understood through a careful study of subsurface hydrology, or hydrogeology, which, according to the Iowa Geological and Water Survey Bureau, “allows better identification for sources, pathways and delivery points for groundwater and contaminants transported through the watershed’s subsurface geological plumbing system.” Diagram courtesy of Iowa DNR Iowa Geological Survey The highly developed karst topography and highly permeable bedrock layers of the Upper Iowa River increase the depth from which actively circulating groundwater contributes to stream flows, making an understanding of the hydrogeology even more important. Fortunately, the Iowa Geological and Water Survey Bureau completed a detailed mapping project of bedrock geologic units, key subsurface horizons, and surficial karst features in the Iowa portion of the Upper Iowa River watershed in 2011. The project “provides information on the subsurface part of the watersheds, which is necessary for evaluating the vulnerability of groundwater to nonpoint-source contamination, the groundwater contributions to surface water contamination, and for targeting best management practices for water quality improvements.” The map on the right shows the surface elevation of bedrock in the state of Iowa and the Upper Iowa River Watershed.
  • Columnals (PDF)

    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.

M. Bristol and Ronald Prescott ABSTRACT The Tuscola Anticline, in east-central Illinois, lies astride the complex LaSalle Anticlinal Belt and dips steeply westward into the Fairfield Basin and gradually eastward into the Murdock Syncline. The anticline is broken into two structural highs, the Hayes Dome and the Shaw Dome. Pleistocene sediments, 50 to 250 feet thick, cover the area. Pennsylvanian sediments cover much of the area, thinning to expose an inlier of Mississippian, Devonian, and Silurian rock north of Tuscola. The basal Cambrian for- mation, the Mt. Simon Sandstone, is penetrated by only two wells. Oil production from the Kimmswick (Trenton) com- menced in 1962 from the R. D. Ernest No. 1 Schweighart well, near Hayes, and as of January 1, 1968, approximately 30 wells were producing oil. Cumulative oil production as of January 1, 1968, is approximately 94,000 barrels. The potential pay zone is confined to the upper 5 to 100 feet of structure and to the upper 125 feet of the Kimmswick, whose permeability ranges from 0.1 to 2. millidarcys, av- eraging 0.6, and whose porosity ranges from 2 to 12 per- cent.

    information t o u s e r s This material was produced from a microfilm copy of the original document. While the most advanced technological means to photograph and reproduce this document have been used, the quality is heavily dependent upon the quality of the original submitted. The following explanation of techniques is provided to help you understand markings or patterns which may appear on this reproduction. 1.The sign or "target” for pages apparently lacking from the document photographed is "Missing Page(s)". If it was possible to obtain the missing page(s) or section, they are spliced into the film along with adjacent pages. This may have necessitated cutting thru an image and duplicating adjacent pages to insure you complete continuity. 2. When an image on the film is obliterated with a large round black mark, it is an indication that the photographer suspected that the copy may have moved during exposure and thus cause a blurred image. You will find a good image of the page in the adjacent frame. 3. When a map, drawing or chart, etc., was part of the material being photographed the photographer followed a definite method in "sectioning" the material. It is customary to begin photoing at the upper left hand corner of a large sheet and to continue photoing from left to right in equal sections with a small overlap.
