This is one of many related papers that were included in the 2012 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks. -

The Turonian - Coniacian Boundary in the United States Western Interior
Acta Geologica Polonica, Vol. 48 (1998), No.4, pp. 495-507 The Turonian - Coniacian boundary in the United States Western Interior IRENEUSZ WALASZCZYKI & WILLIAM A. COBBAN2 I Institute of Geology, University of Warsaw, AI. Zwirki i Wigury 93, PL-02-089 Warszawa, Poland E-mail: [email protected] 270 Estes Street, Lakewood, Colorado 80226, USA ABSTRACT: WALASZCZYK, I. & COBBAN, W.A. 1998. The Turonian - Coniacian boundary in the United States Western Interior. Acta Geologica Polonica, 48 (4),495-507. Warszawa. The Turonian/Coniacian boundary succession in the United States Western Interior is characterized by the same inoceramid faunas as recognized in Europe, allowing the application of the same zonal scheme in both regions; Mytiloides scupini and Cremnoceramus waltersdorfensis waltersdorfensis zones in the topmost Turonian and Cremnoceramus deformis erectus Zone in the lowermost Coniacian. The correla tion with Europe is enhanced, moreover, by a set of boundary events recognized originally in Europe and well represented in the Western Interior: Didymotis I Event and waltersdorfensis Event in the topmost Turonian, and erectus I, II and ?III events in the Lower Coniacian. First "Coniacian" ammonite, Forresteria peruana, appears in the indisputable Turonian, in the zone of M. scupini, and the reference to Forresteria in the boundary definition should be rejected. None of the North American sections, pro posed during the Brussels Symposium as the potential boundary stratotypes, i.e. Wagon Mound and Pueblo sections, appears better than the voted section of the Salzgitter-Salder. The Pueblo section is relatively complete but markedly condensed in comparison with the German one, but it may be used as a very convenient reference section for the Turonian/Coniacian boundary in the Western Interior. -

E-mail: [email protected] ABSTRACT: REMIN, Z. 2004. Biostratigraphy of the Santonian in the SW margin of the Holy Cross Mountains near Lipnik, a poten tial reference section for extra-Carpathians Poland. Acta Geologica Polonica, 54 (4), 587-596. Warszawa. The set of outcrops near the village of Kije, on the SW margin of the Holy Cross Mountains provides a nearly com plete Santonian succession that has a great potential to become a Santonian reference section in Poland. The Coniacian/Santonian boundary is defined here by the first occurrence (FO) of the inoceramid bivalve species Cladoceramus undulatoplicatus (ROEMER 1852). The uppermost Santonian is characterized by common Sphenoceramus patootensiformis (SEITZ 1965). The top of the stage (and the base of the Campanian Stage) is docu mented by the last occurrence (LO) of the crinoid species Marsupites testudinarius (SCHLOTHEIM 1820). The substage division of the Santonian is based on inoceramids, with the lower boundary of the Middle Santonian indicated by the LO of Cladoceramus undulatoplicatus and the base of the Upper Santonian by the FO of representatives of Cordiceramus muelleri (PETRAS CHECK 1906) group. Keywords: Cretaceous, Santonian, Stratigraphy, Biostratigraphy, Magnetostratigraphy, Ammonites, Inoceramid bivalves, Crinoids.

Geologos 18, 2 (2012): 83–109 doi: 10.2478/v10118-012-0007-z Palaeontology of the Middle Turonian limestones of the Nysa Kłodzka Graben (Sudetes, SW Poland): biostratigraphical and palaeogeographical implications Alina Chrząstek Institute of the Geological Sciences, Wrocław University, Maksa Borna 9, PL 50-204 Wrocław, Poland; e-mail: [email protected] Abstract The ammonites Lewesiceras peramplum Mantell and ?Lewesiceras sp. are reported from the Upper Cretaceous in the Nysa Kłodzka Graben; they date from the Middle Turonian and ?Coniacian, respectively. The Middle Turonian lime- stones of the Stara Bystrzyca quarry contain an abundant assemblage of inoceramids (Inoceramus cuvieri Sowerby and I. lamarcki Parkinson) and other bivalves, including oysters, as well as brachiopods and trace fossils. Micropalaeonto- logical data show the presence of foraminifers and siliceous sponge spiculae, bryozoans, ostracods and fragments of bivalves and gastropods. The Middle Turonian calcareous deposits belongs to the upper part of the Inoceramus lamarcki Zone (late Middle Turonian) and were deposited on a shallow, subtidal offshore shelf. They overlie the Middle Turo- nian Bystrzyca and Długopole Sandstones, which represent foreshore-shoreface delta deposits. The fossil assemblage suggests a moderate- to low-energy, normal-salinity environment with occasionally an oxygen deficit.
