Middle Eocene Lisbon Formation Miles O0123452 3 4 5 THE LITHOSTRATIGRAPHIC FRAMEWORK OF THE UPPERMOST CRETACEOUS AND LOWER TERTIARY OF EASTERN BURKE COUNTY, GEORGIA Paul F. Huddlestun and Joseph H. Summerour GEORGIA DEPARTMENT OF NATURAL RESOURCES Lonice C. Barrett, CommissionerCommhioner ENVIRONMENTAL PROTECTION DIVISION Harold F. Reheis, Director GEORGIA GEOLOGIC SURVEY William H. McLemore, State Geologist Atlanta 19961906 Bulletin 127 ABSTRACT One new formation, two new members, and a reclefhitionredefinition of an established lithostratigraphic unit are formally introduced here. The Oconee Group is formally recognized in the Savannah River area and four South Carolina Formations not previously used in Georgia by the Georgia Geologic Survey are recognized in easterndrnBurke County. The Still Branch Sand is a new formation and the two new members are the Bennock Millpond Sand Member of the Still Branch Sand and the Blue Bluff Member of the Lisbon Formation. The four South CarolinaCarob formations recognized in eastern Burke CountyCountY include the Steel Creek Formation and Snapp Formation of the Oconee Group, the Black Mingo Formation (undifferentiated), and the Congaree Formation. The Congaree Formation and Still Branch Sand are considered to be lithostratigraphic components of the Claiborne Group. The Congaree Formation is included in the Claiborne Group because it extends westward to the Chattahoochee River area of Georgia and Alabama, and perhaps farther west into Alabama. In this area, the Congaree has been called the TallahatlaTallahatta Formation for many years and the Alabama and w-rnwestern Georgia "Tallahatta""Tallahatla" is an essential formation of the Claiborne Group. The age and correlation of all of the lithostratigraphic unitaunits are discussed. In addition, the Pen Branch fault is recognized in the vicinity of Hancock Landing in eastern Burke County. i TABLETABLE OFOF CONrENTSCONTENlW IN"TRODUCTIONINTRODUCTION ............................................................1............................................................ 1 PurposePurposeandSeopeand Scope ..................................................... 11 LocationLocationofStudyAreaof Study Area .................................................. 11 PhysiographicPhysiographicsettingSetting ................................................... 11 PreviousPreviousWorkWork ....................................................... 11 MethodsMethods ............................................................. 33 AcknowledgementsAcknowledgements ..................................................... 33 GEOLOGYGEOLOGY ANDAND HYDROLOGYHYDROLOGY .................................................5 5 GeologicGeologicSettingSetting .......................................................5 5 HydrogeologicHydrogeologicSettingSetting ...................................................66 StructuralStruch.lralFeature~sFeatures ........................................................................................................ 10 10 STRATIGRAPHYSTRATIGRAPHY ...........................................................12 12 OconeeOconeeGroupGroup ................................................................................................................12 12 SteelSteelCreekFormationCreek Formation ........................................................................................1414 SnappSnappFormationFormation ................................................................................................1717 Undift'erentiatedUndifferentiatedBLackMingoFormationBlack Mingo Formation ...............................2323 ClaiborneClaiborneGroupGroup ......................................................3131 CongareeCongareeFormationFormation ............................................................................................3333 StillStillBranchSandBranch Sand ...............................................4343 BennockBennock MillpondMillpond SandSand Member.Member ............................................................. 4848 LisbonLisbonFormationFormation ...............................................5363 BlueBlue BluffBluff MemberMember ..................................................................................5656 McBeanMcBean LimestoneLimestone MemberMember ..................................6262 BarnwellBarnwellGroupGroup ..............................................................................................................6464 ClinchfieldClincMeldFomationFormation ..........................................................................................6666 UtleyUtley LimestoneLimestone MemberMember ....................................6666 DryDryBranchFormationBranch Formation ........................................................................................6868 TwiggsTwiggs ClayClay LithofaciesLithofacies .....................................7070 GriffinsGriflins LandingLanding MemberMember ........................................................................ 7070 IrwintonIrwinton SandSand MemberMember ............................................................................7171 TobaccoTobaccoRoadSandRoad Sand ..............................................7272 REFERENCESREFERENCESCITEDCITED .......................................................73 73 FIGURESFIGURES 1.

  • Synoptic Taxonomy of Major Fossil Groups
    APPENDIX Synoptic Taxonomy of Major Fossil Groups Important fossil taxa are listed down to the lowest practical taxonomic level; in most cases, this will be the ordinal or subordinallevel. Abbreviated stratigraphic units in parentheses (e.g., UCamb-Ree) indicate maximum range known for the group; units followed by question marks are isolated occurrences followed generally by an interval with no known representatives. Taxa with ranges to "Ree" are extant. Data are extracted principally from Harland et al. (1967), Moore et al. (1956 et seq.), Sepkoski (1982), Romer (1966), Colbert (1980), Moy-Thomas and Miles (1971), Taylor (1981), and Brasier (1980). KINGDOM MONERA Class Ciliata (cont.)

Publication Date 2014-05-27 Peer reviewed eScholarship.org Powered by the California Digital Library University of California PaleoBios 31(1):1–32, May 27, 2014 Paleogene chelonians from Maryland and Virginia ROBERT E. WEEMS Paleo Quest, 14243 Murphy Terrace, Gainesville, Virginia, 20155, USA; [email protected] Fossil remains of 22 kinds of Paleogene turtles have been recovered in Maryland and Virginia from the early Paleocene Brightseat Formation (four taxa), late Paleocene Aquia Formation (nine taxa), early Eocene Nanje- moy Formation (five taxa), middle Eocene Piney Point Formation (one taxon), and mid-Oligocene Old Church Formation (three taxa). Twelve taxa are clearly marine forms, of which ten are pancheloniids (Ashleychelys palmeri, Carolinochelys wilsoni, Catapleura coatesi, Catapleura sp., Euclastes roundsi, E. wielandi, ?Lophochelys sp., Procolpochelys charlestonensis, Puppigerus camperi, and Tasbacka ruhoffi), and two are dermochelyids (Eosphargis insularis and cf. Eosphargis gigas). Eight taxa represent fluvial or terrestrial forms (Adocus sp., Judithemys kranzi n. sp., Planetochelys savoiei, cf. “Trionyx” halophilus, “Trionyx” pennatus, “Kinosternoid B,” Bothremydinae gen. et sp. indet., and Bothremydidae gen. et sp. indet.), and two taxa (Aspideretoides virgin- ianus and Allaeochelys sp.) are trionychian turtles that probably frequented estuarine and nearshore marine environments. In Maryland and Virginia, turtle diversity superficially appears to decline throughout the Pa- leogene, but this probably is due to an upward bias in the local stratigraphic column toward more open marine environments that have preserved very few remains of riverine or terrestrial turtles.
