Palaeoenvironmental evolution of the Southern Alps across the Faraoni Level equivalent: new data from the Trento Plateau (Upper Hauterivian, Dolomites, N. Italy). Acta Geologica Polonica, 63 (1), 89–104. Warszawa. New stratigraphic and palaeoenvironmental data are presented for the northeastern part of the Trento Plateau (Puez area, Southern Alps, Italy). The studied section corresponds to the upper Hauterivian Balearites balearis and “Pseudothurmannia ohmi” ammonite zones and normal palaeomagnetic chron upper M5. A c. 30-cm-thick bed is identified as the equivalent of the Faraoni Level, based on its position within the Pseudothurmannia mortilleti Sub- 13 zone, the composition of its ammonite fauna and the peak of a minor positive trend in the δ Cbulk record. Microfa- cies and geochemical proxies compare well with those of the southeastern part of the Trento Plateau and indicate palaeoceanographic continuity along the eastern margin of the plateau. The abundances of radiolarians and nanno- conids suggest a turnover in the trophic structure from eutrophic conditions around the Faraoni Level equivalent to oligotrophic conditions.

  • Stratigraphic Implications of a New Lower Cretaceous Ammonoid Fauna from the Puez Area (Valanginian – Aptian, Dolomites, Southern Alps, Italy)
    Geo.Alp, Vol. 3, S. 55–83, 2006 STRATIGRAPHIC IMPLICATIONS OF A NEW LOWER CRETACEOUS AMMONOID FAUNA FROM THE PUEZ AREA (VALANGINIAN – APTIAN, DOLOMITES, SOUTHERN ALPS, ITALY) Alexander Lukeneder1 & Christian Aspmair2 With 6 figures and 8 plates 1 Natural History Museum, Geological-Palaeontological Department, Burgring 7, A-1010 Wien, Austria, e-mail: [email protected] 2 Prissian 102, I – 39010 Tisens (BZ), Italy Abstract Lower Cretaceous ammonoids (n = 424) were collected at the Puez locality in the Dolomites of Southern Tyrol. The cephalopod fauna from the marly limestones to marls here indicates Late Valanginian to Early Aptian age. The deposition of the marly limestones and marls of this interval occurred during depositional- ly unstable conditions. The underlying Biancone Formation (Maiolica Formation) is of Early Valanginian, whereas the lowermost Rosso Ammonitico is of Jurassic to Berriasian age. The ammonoid fauna consists of 27 different genera, each represented by 1-2 species. The assemblage at the Puez section is dominated by the Phylloceratina (30%) and the Ammonitina (34%). Phyllopachyceras (17%) and Phylloceras (13%) (both Phylloceratina) are the most frequent components, followed by Lytoceras (12%) (Lytoceratina), and Barremites (10%) and Melchiorites (8%) (both Ammonitina). The cephalopod fauna is purely of Mediterranean origin. Zusammenfassung Unterkreide Ammonoideen (424 Exemplare) der Puez Lokalität in den Dolomiten Süd-Tirols wurden unter- sucht.

  • The Barremian Heteromorph Ammonite Dissimilites from Northern Italy: Taxonomy and Evolutionary Implications
    The Barremian heteromorph ammonite Dissimilites from northern Italy: Taxonomy and evolutionary implications ALEXANDER LUKENEDER and SUSANNE LUKENEDER Lukeneder, A. and Lukeneder, S. 2014. The Barremian heteromorph ammonite Dissimilites from northern Italy: Taxon- omy and evolutionary implications. Acta Palaeontologica Polonica 59 (3): 663–680. A new acrioceratid ammonite, Dissimilites intermedius sp. nov., from the Barremian (Lower Cretaceous) of the Puez area (Dolomites, northern Italy) is described. Dissimilites intermedius sp. nov. is an intermediate form between D. dissimilis and D. trinodosum. The new species combines the ribbing style of D. dissimilis (bifurcating with intercalating single ribs) with the tuberculation style of D. trinodosum (trituberculation on entire shell). The shallow-helical spire, entirely comprising single ribs intercalated by trituberculated main ribs, is similar to the one of the assumed ancestor Acrioceras, whereas the increasing curvation of the younger forms resembles similar patterns observed in the descendant Toxoc- eratoides. These characters support the hypothesis of a direct evolutionary lineage from Acrioceras via Dissimilites to Toxoceratoides. D. intermedius sp. nov. ranges from the upper Lower Barremian (Moutoniceras moutonianum Zone) to the lower Upper Barremian (Toxancyloceras vandenheckii Zone). The new species allows to better understand the evolu- tion of the genus Dissimilites. The genus appears within the Nicklesia pulchella Zone represented by D. duboise, which most likely evolved into D. dissimilis. In the Kotetishvilia compressissima Zone, two morphological forms developed: smaller forms very similar to Acrioceras and forms with very long shaft and juvenile spire like in D. intermedius sp. nov. The latter most likely gave rise to D. subalternatus and D. trinodosum in the M.

Komm. 15: 295-313, 4 Figs., 3 Pis., Wien. Abstract: Biostratigraphie and lithostratigraphic studies have been made on four boreholes (Ago­ styan Agt-2, Neszmely N-4, Tatabänya Ta-1472, Ta-1486) in the Gerecse Mts. and the Tatabanya basin in Hungary. The Lower Cretaceous succession of this area comprises the Neszmely Sandstone Formation (NSF, Barremian-Aptian), the Tata Limestone Formation(TLF, Aptian) and the Vertes­ som16 Formation (VF, Lower and Middle Albian). In its stratotype, borehole N-4, the NSF was subdivided into four integrated ammonite and planktonic foraminifera zones from top to bottom: The Ticinella bejaouensis ivz - Hedbergella gorbachikae ivz (Late Aptian - ?Early Albian), the G/obigerinelloides algerianus trz (early Late Aptian), the Shackoina cabrii trz - Globigerinelloides blowi ivz (Early and Mid Aptian), and the Hedbergella sigali ivz (Barremian). In the lower and middle part of the Sh. cabrii trz - GI. blowi ivz the ammonites Procheloniceras albrechtiaustriae HoH., Pseudosaynella ex gr. matheronites (o'ORBIGNY), and Barremites difficilis (o'ORBIGNY) indicate the Early Aptian Deshayesites weissi ammonite Zone. In the H. sigali ivz Costidiscus redicostatus (o'ORBIGNY) and Spitidiscus vandeckii (o'ORBIGNY) give evidence for a Barremian age.

This faunal turnover took place following a stepwise pattern. The first step occurred at the boundary between the Pseudothurmannia ohmi Subzone and the Pseudothurmannia mortilleti Subzone, coinciding with the base of the so-called Faraoni Level. This is a Corg- rich interval that has been recognised in several basins of the Mediterranean Tethys and seems to be the expression of a short- lived oxygen-deficient event. It correlates with a well-documented second-order peak transgression. The oxygen depletion preferentially affected the deep nektic ammonites, which would explain the extinctions within this group around the Faraoni Level. On the contrary, an increase in the trophic resources in the photic zone favoured the diversification of epipelagic ammonites. Concurrently, an abrupt change took place at this level in the nannoconid assemblage composition. A minor second event, located at the base of the Pseudothurmannia picteti Subzone, was marked by the replacement of a few planktic ammonite species by closely related forms, and the structure of the ammonite assemblage was not substantially altered.

NUMBER 2005 JUNE 15, 1960 Lower Cretaceous Ammonites from Colombia, South America BY OTTO HAAS INTRODUCTION The present paper attempts to summarize the paleontological re- sults of an investigation carried out early in 1956, under the sponsor- ship of International Petroleum (Colombia), Ltd., in the Cordillera Oriental of Colombia for the purpose of clarifying and refining the lower Cretaceous stratigraphy of that region. I am indebted to the company for permission to publish this paper and to utilize photo- graphs made at the company's expense, and to Prof. Gerardo Botero Arango of the Facultad Nacional de Minas of Medellin, Colombia, for permission to describe specimens collected on a field trip of that institution and now deposited in its collections. For the repositories of illustrated specimens, reference is made to the legends of the figures accompanying the present report; there "I.P." indicates the collec- tions of International Petroleum (Colombia), Ltd., in Bogota and "F.N.M." those of the Facultad Nacional de Minas in Medellin. In addition to most of the forms recognized among the abundant ammonites collected in the course of the above investigation, some interesting specimens that had been in the company's collections earlier are also included in the present report. Unfortunately most of the ammonites here described, especially those preserved in shales, are crushed and flattened or otherwise dis- torted; venters can be examined only exceptionally and even more rarely can suture lines be observed.

Their rapid evolution and diversifi- cation make them one of the key groups for that period, but their origin remains poorly known and several competing hypotheses have been published. These hypotheses are tested here with cladistic analysis in order to reject those receiving the least support and discuss those well supported.
