Sucesión De Amonitas Del Cretácico Superior (Cenomaniano – Coniaciano) De La Parte Más Alta De La Formación Hondita Y De L
Boletín de Geología Vol. 33, N° 1, enero-junio de 2011 SUCESIÓN DE AMONITAS DEL CRETÁCICO SUPERIOR (CENOMANIANO – CONIACIANO) DE LA PARTE MÁS ALTA DE LA FORMACIÓN HONDITA Y DE LA FORMACIÓN LOMA GORDA EN LA QUEBRADA BAMBUCÁ, AIPE - HUILA (COLOMBIA, S. A.) Pedro Patarroyo1 RESUMEN La sección de la quebrada Bambucá (Aipe - Huila) posee una buena exposición de los depósitos del Cretácico del Valle Superior del Magdalena. De la parte alta de la Formación Hondita se recolectaron Acanthoceras sp. y Rhynchostreon sp. del Cenomaniano superior. Dentro del segmento inferior de la Formación Loma Gorda se hallaron Choffaticeras (C.) cf. segne, Fagesia cf. catinus, Neoptychites cf. andinus, Mitonia gracilis, Morrowites sp., Nannovascoceras ? sp., Quitmaniceras ? sp., Benueites ? sp. junto con Mytiloides kossmati, M. goppelnensis y Anomia sp. del Turoniano inferior. Estratigráficamente arriba aparecen Paramammites ? sp., Hoplitoides sp. H. ingens, H. cf. lagiraldae, Codazziceras ospinae, Allocrioceras sp., que pueden estar representando entre el Turoniano inferior y medio. Para la parte alta de este segmento se encontraron Prionocycloceras sp. P. guayabanum, Reesidites subtuberculatum, Subprionotropis colombianus, Mytiloides scupini, Dydimotis sp., Gauthiericeras sp., Anagaudryceras ? sp., Eulophoceras jacobi, Paralenticeras sieversi, Hauericeras cf. madagascarensis, Peroniceras (P.) subtricarinatum, Forresteria (F.) sp., Barroisiceras cf. onilahyense, Ankinatsytes venezolanus que abarcan entre el Turoniano superior y el Coniaciano. Con base en la fauna colectada no es posible establecer los límites Cenomaniano/Turoniano y Turoniano/Coniaciano. Palabras clave: Amonitas, Cretácico superior, Valle Superior del Magdalena, Aipe-Huila-Colombia.

MEXICO. E-mail address:[email protected] 2T.H. Huxley School of Environment, Earth Science and Engineering, Imperial College of Science Technology and Medicine, Prince Consort Road, London SW7 2BP, UK. Received: 22/10/03 / Accepted: 16/06/04 Abstract The Cenomanian-Turonian succession of the Guerrero-Morelos basin contains a number of paloecommunities that can be cor- related. These palaeocommunities have been recognized and interpreted as the result of environmental disturbances. Some of these bioevents are probably local (platform-wide) and reflect successive stages of the platform drowning, whereas others have equiva- lents in other parts of the world and are probably linked to global paleoceanographic changes. Bioevents that can be used for cor- relation are: 1) the last appearance of Pseudorhapydionina dubia (94.4Ma); 2) the disappearance of most large benthic foraminifers and calcareous algae (94.2Ma); 3) the first appearance of hippuritid mollusks (93.5Ma); 4) the first appearance ofHelvetoglobotrun - cana helvetica (93.0Ma) accompanied by a diversification of keeled planktonic foraminifers. Increase in13 C and TOC values in the deeper-water facies covering the carbonate platform suggests a probable link between the drowning of the platform and the global Cenomanian-Turonian Anoxic Event. The deposition of organic-rich facies in the upper Whiteinella archaeocretacea and lower Helvetoglobotruncana helvetica Zones is associated with the establishment of oxygen poor and eutrophic conditions. -
Ammonite Faunal Dynamics Across Bio−Events During the Mid− and Late Cretaceous Along the Russian Pacific Coast
Ammonite faunal dynamics across bio−events during the mid− and Late Cretaceous along the Russian Pacific coast ELENA A. JAGT−YAZYKOVA Jagt−Yazykova, E.A. 2012. Ammonite faunal dynamics across bio−events during the mid− and Late Cretaceous along the Russian Pacific coast. Acta Palaeontologica Polonica 57 (4): 737–748. The present paper focuses on the evolutionary dynamics of ammonites from sections along the Russian Pacific coast dur− ing the mid− and Late Cretaceous. Changes in ammonite diversity (i.e., disappearance [extinction or emigration], appear− ance [origination or immigration], and total number of species present) constitute the basis for the identification of the main bio−events. The regional diversity curve reflects all global mass extinctions, faunal turnovers, and radiations. In the case of the Pacific coastal regions, such bio−events (which are comparatively easily recognised and have been described in detail), rather than first or last appearance datums of index species, should be used for global correlation. This is because of the high degree of endemism and provinciality of Cretaceous macrofaunas from the Pacific region in general and of ammonites in particular.

Palaeontology of the Middle Turonian Limestones of the Nysa Kłodzka Graben
Palaeontology of the Middle Turonian limestones of the Nysa Kłodzka Graben... 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.
