New Mexico Museum of Natural History and Science, Bulletin 60. 1 THE CONODONT NEOGNATHODUS BOTHROPS MERRILL, 1972 AS THE MARKER FOR THE LOWER BOUNDARY OF THE MOSCOVIAN STAGE (MIDDLE PENNSYLVANIAN) ALEXANDER S. ALEKSEEV1 AND NATALIA V. GOREVA 2 1 Department of Paleontology, Geological Faculty, Moscow State University, Russia, email: aaleks@geol. msu.ru; 2 Geological institute of Russian Academy of Science, Moscow, Russia, email: [email protected] Abstract—The Moscovian Stage constitutes the Middle Pennsylvanian Series of the Carboniferous System, but a biostratigraphic marker and GSSP for it have not yet been designated. The exact position of the Moscovian boundary cannot be defined properly because in the type area the basal Vereian unconformably overlies the Mississippian limestone or the alluvial and lagoonal Aza Formation of the uppermost Bashkirian. The Task Group to establish a GSSP close to the existing Bashkirian-Moscovian boundary suggested several potential markers among foraminifers and conodonts, but the search for a marker near traditional base of the global Moscovian Stage has stalled. It may be more productive to search for FADs in the lower Moscovian, above the traditional base, to designate the lower boundary of the stage. Relatively rich Vereian and Kashirian conodont assemblages have been recovered from the southwest Moscow Basin, as well as from the Oka-Tsna Swell. The most complete information on the distribution of conodonts in the Vereian- Kashirian boundary interval was obtained from the Yambirno section (Oka-Tsna Swell). The greatest change in conodont assemblages does not occur near the level of the traditional base of the Moscovian, but stratigraphically higher. -

(ipmontañ[email protected]). Keywords — Serpukhovian, Bashkirian, biostratigraphy, palaeoecology. Two different tectono-stratigraphic domains are recognised in the Cantabrian Mountains, Asturian-Leo- nese (Cantabrian Zone) and Palentian (Palentian Zone). The area under investigation belongs to the south- ern part of the Palentian Domain and attention is focused on the Upper Viséan to lowermost Bashkirian limestones at the village of La Lastra in northern Palencia. A new geological map of the Palentian Zone is accompanied by a more detailed map centred on La Lastra. The Barcaliente Limestone Formation (Ser- pukhovian to lowermost Bashkirian) occurs in the overturned limb of a recumbent anticline which consti- tutes the head of a south-verging major thrust unit, the Carrionas Thrust Sheet (Palentian Zone). -

1 Correlation of the Base of the Serpukhovian Stage
Correlation of the base of the Serpukhovian Stage (Carboniferous; Mississippian) in northwest Europe GEORGE D. SEVASTOPULO* & MILO BARHAM✝ *Department of Geology, Trinity College Dublin, Dublin 2, Ireland ✝Milo Barham, Department of Applied Geology, Curtin University of Technology, GPO Box U1987, Perth, WA 6845, Australia Author for correspondence: [email protected] Running head: Correlation base Serpukhovian northwest Europe Abstract - The Task Group charged with proposing the GSSP for the base of the Serpukhovian Stage (Mississippian: Lower Carboniferous) is likely to use the global First Appearance Datum (FAD: evolutionary first appearance) of the conodont Lochriea ziegleri in the lineage Lochriea nodosa-L. ziegleri for the definition and correlation of the base of the stage. It is important to establish that the FOD (First Occurrence Datum) of L. ziegleri in different basins is essentially penecontemporaneous. Ammonoids provide high-resolution biostratigraphy in the late Mississippian but their use for international correlation is limited by provincialism. However, it is possible to assess the levels of diachronism of the FOD of L. ziegleri in sections in northwest Europe using ammonoid zones. Published compilations of conodont distribution in the Rhenish Slate Mountains of Germany show the FOD of L. ziegleri in the Emstites novalis Biozone (upper part of the P2c zone of the British/Irish ammonoid biozonation) but L. ziegleri has also been reported as occurring in the Neoglyphioceras spirale Biozone (P1d zone). In the Yoredale Group of northern England, the FOD of L. ziegleri is in either the P1c or P1d zone. In NW Ireland, the oldest records of both L. nodosa and L. ziegleri are from the Lusitanoceras granosum Biozone (P2a). -

Paleontological Contributions
THE UNIVERSITY OF KANSAS PALEONTOLOGICAL CONTRIBUTIONS May 15, 1970 Paper 47 SIGNIFICANCE OF SUTURES IN PHYLOGENY OF AMMONOIDEA JURGEN KULLMANN AND JOST WIEDMANN Universinit Tubingen, Germany ABSTRACT Because of their complex structure ammonoid sutures offer best possibilities for the recognition of homologies. Sutures comprise a set of individual elements, which may be changed during the course of ontogeny and phylogeny as a result of heterotopy, hetero- morphy, and heterochrony. By means of a morphogenetic symbol terminology, sutural formulas may be established which show the composition of adult sutures as well as their ontogenetic development. WEDEKIND ' S terminology system is preferred because it is the oldest and morphogenetically the most consequent, whereas RUZHENTSEV ' S system seems to be inadequate because of its usage of different symbols for homologous elements. WEDEKIND ' S system includes only five symbols: E (for external lobe), L (for lateral lobe), I (for internal lobe), A (for adventitious lobe), U (for umbilical lobe). Investigations on ontogenetic development show that all taxonomic groups of the entire superorder Ammonoidea can be compared one with another by means of their sutural development, expressed by their sutural formulas. Most of the higher and many of the lower taxa can be solely characterized and arranged in phylogenetic relationship by use of their sutural formulas. INTRODUCTION Today very few ammonoid workers doubt the (e.g., conch shape, sculpture, growth lines) rep- importance of sutures as indication of ammonoid resent less complicated structures; therefore, phylogeny. The considerable advances in our numerous homeomorphs restrict the usefulness of knowledge of ammonoid evolution during recent these features for phylogenetic investigations. -
Early Permian Ammonoids from the Takakurayama Area, Abukuma Mountains, Northeast Japan Masayuki FUJIKAWA* and Chisato SUZUKI**
Sci. Rep., Niigata Univ. (Geology), No. 26, 61-72, 2011 61 Early Permian ammonoids from the Takakurayama area, Abukuma Mountains, northeast Japan Masayuki FUJIKAWA* and Chisato SUZUKI** Abstract Four ammonoid species, Thalassoceras? sp., Artinskia sp., Agathiceras sp., and Paragastrioceras? sp., are described from the lower part of the Takakurayama Formation in the Takakurayama area, Abukuma Mountains, northeast Japan. This fauna indicates an Early Permian (Sakmarian-Artinskian) age. Three of these species except for Agathiceras sp. are described from the Takakurayama Formation for the first time. Key words: Abukuma Mountains, ammonoid, Early Permian, Takakurayama. Introduction The Permian Takakurayama Formation (Onuki, 1966) is widely distributed in the Takakurayama area, Abukuma Mountains, South Kitakami Belt, northeast Japan (Fig. 1). The formation is exposed on the northeastern slope of Mt. Takakurayama, where it generally strikes NNE-SSW and dips at 30-45º to the west. It consists mainly of black shale with subordinate sandstone and conglomerate, and is more than 805 m in total thickness (Fig. 2). The formation is subdivided into three members: the Iriishikura, Motomura, and Kashiwadaira members, in ascending order (Onuki, 1966). These members are equivalent to the Iriishikura, Motomura, and Kashiwadaira formations proposed by Yanagisawa and Nemoto (1961). Here, we adopt Onuki’s scheme, and refer to the lower part of the Takakurayama beds as the Iriishikura Member.
