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.

Accepted 30 March 201 0 A new heteromorphammonite genus, Tarrantites, is proposed for Hamites adkinsi Scott, 1928. The description of the new genus is based mainly on a near<omplete specimen from the Middle Albian part of the G:1odland Limestone of Tarrant County, Texas, the holotype, and on an abraded mould on a pebble from the bed of a stream in Hill County, Texas. In addition, we record the presence of the genus in the Albian of Pakistan. Tarrantites shows a remarkable resemblance to the labeceratine genera Labeceras Spath, 1925 and Myloeeras Spath, 1925: in coiling and size to the former, and in ornamentation to the latter, but is excluded from the subfamily Labeceratinae Spath, 1925, because it has a distinct bifid adventive (A) lobe. This latterfeature, and the ornamentation, rather suggest affinities of Tarrantites with the family Anisoceratidae Hyatt, 1900.

Didier BERT 1, 2 Stéphane BERSAC 2 Abstract: The Late Barremian Hemihoplitidae (Ancyloceratina, Ammonoidea) are widely known in the northern Tethyan Margin and the Essaouira-Agadir Basin (Morocco). 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.

The ammonite assemblages described herein are from the Nimbolook and Kerch sections located west of Qayen. The following taxa are described: Mantelliceras mantelli (J. SOWERBY, 1814), Mantelliceras saxbii (SHARPE, 1857), Mantelliceras sp. 1, Mantelliceras sp. 2, Mantelliceras sp. 3, Sharpeiceras laticlavium (SHARPE, 1855), Sharpeiceras schlueteri (HYATT, 1903), Puzosia (Puzosia) mayoriana (ORBIGNY, 1841), Hyphoplites costosus C.W.

SOWERBY, 1814), Caly- coceras (Gentoniceras) aff. gentoni (BRONGNIART, 1822), Idiohamites fremonti (MARCOU, 1858), Mariella (Mariella) sp., Mariella (Mariella) dorsetensis (SPATH, 1926), and Turrilites costatus LAMARCK, 1801. The ammonite assemblages clearly indicate a late Albian-middle Cenomanian age for the Nimbolook section and late Albian-early Cenomanian age for the Kerch section.

Ammonite Faunas from Condensed Cenomanian-Turonian Sections ('Tourtias') in Southern Belgium and Northern France

Email: [email protected]. Manuscript received: November 2010; accepted: July 2011 Abstract In southern Belgium (Mons Basin and Tournai region) and northern France (area between Lille, Valenciennes and Maubeuge), condensed sequences have been referred to as ‘tourtias’ since the start of the nineteenth century. These levels correspond to a succession of trangressive systems tracts and generally appear as dark green, glauconitic and microconglomeratic facies. They are distributed all along the base of the more important transgressive systems tracts of the Cenomanian and basal Turonian from the Boulonnais (northwest France) to the Mons Basin (southern Belgium), through the Artois and Douaisis. Their age can now be determined more accurately by identification of their ammonite content, as housed in museums such as the Institut royal des Sciences naturelles de Belgique (IRScNB, Brussels) and the Musée d’Histoire naturelle de Lille (MHNL). Here material from the IRScNB collections is described, illustrated and discussed; specimens contained in the MHNL collections were described in a previous paper.
