  • 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.

  • 64. the Akiyoshi Orogenic Cycle in the Mongolian Geosyncline*. by Teiichi KOBAYASHI
    306 [Vol. 18, 64. The Akiyoshi Orogenic Cycle in the Mongolian Geosyncline*. By Teiichi KOBAYASHI. (Comm.by T. KATO,M.I.A., June 12, 1942.) Since Schonmann had expressed the opinion in 1929 that the Mongolio-Amur Faltengurtel had been a geosyncline which was disturbed by late Mesozoic orogenses, it was a moot question among geologists, as discussed by Stille, Obrutschew and othersl'. It is the object of this paper to demonstrate that the Akiyoshi, instead of the Sakawa, cycle of orgenesis2' is responsible for the oronization of the Mongolian geosyncline. A thick Palaeozoic complex for which I proposed the name , Mammo ( i) group3', is the sediment in the geosyncline existing between the Altenseheitel and the Yenshan orogenic zone. Because it is one of the least known but nevertheless one of the most important f ormational unit in the geology of Eastern Asia, I have paid special attention to it since I studied a small collecl,ion of fossils from Soron in the middle part of the Great Khingan range in 19314'. On the basis of fresh evidences which we obtained in Manchoukuo, its stratigraphic succession can now be roughly sketched as follows : 1. The lowest of the group so far known is the Ordovician Orthis sandstone of the Tyktaminda on the Siberian side of the Upper Amur valley where it is overlain by the Gotlandian Galymene manly shale. In the same area there is a good display of the fossiliferousDevonian formation composedmostly of shale and limestone in the lower part, of marl, limestone and reef limestone in the middle and of limestone in the upper parts).

Tun development of the ammonites cannot be discussed independently of the evolution of their Palaeozoic forerunners, the goniatites, and the earlier types of these, again, are very intimately allied to the ancestral nautiloids. Although some- what diffident of casting so wide a net, I feel that the problem of the evolution of the Cephalopoda must be restated. In the past, what in my opinion are erroneous views of the development of the Ammonoidea have been popularisedlargelythrough the enthusiasm of workers who were attracted to the subject but had little practical experience of ammonites, and who too often were inclined to treat these fossils not as the remains of natural organisms but as material for speculation. This article, however, not only criticises the prevalent view that the ammonites, like the ancestral goniatites and Clymenia, arose from a straight nautiloid (Bactrites) and then hurried through the early stages of coiling before uncoiling again towards the end of their career; it also discusses various views put forward by workers on the primitive nautiloids.

Received in original form 1996 March 26 SUMMARY Magnetobiostratigraphic data are presented from three Early/Middle Triassic Han- Bulog Limestone successions from Kqira, northern Albania. A total of 206 standard palaeomagnetic samples were obtained for thermal demagnetization and statistical analysis from the 42, 10 and 5m thick sections. The reversal-bearing characteristic component, carried by haematite and magnetite, defines a composite sequence of six main polarity intervals (Kqln to Kq3r) in which are embedded four short polarity intervals, one at the base of Kqln and three towards the top of Kqlr. The early acquisition of the characteristic remanence is supported by the lateral correlation of magnetozones between sections. The Early/Middle Triassic boundary, approximated by the first occurrence of the conodont Chiosella timorensis, falls close to the Kqlr/Kq2n polarity transition. This is in good agreement with recently published magneto- biostratigraphic data from the coeval Chios (Greece) sections. The palaeomagnetic pole calculated from the Kqira characteristic directions lies close to the Triassic portion of the apparent polar wander path for Laurussia (in European coordinates). However, a 40-45" clockwise rotation of the external zone of the Albano-Hellenic Belt to the south of the Scutari-Pec Line is thought to have occurred since the Early-Middle Miocene.

    DEPARTMENT OF THE INTERIOR TO ACCOMPANY MAP MF-ZOO7 U.S. GEOLOGICAL SURVEY FOSSIL LOCALITY MAP AND FOSSIL DATA FOR THE SOUTHEASTERN PART OF THE CHARLEY RIVER QUADRANGLE. EAST-CENTRAL ALASKA Compiled by Ronny T. Miyaoka INTRODUCTION This table and location map are compiled from fossil information collected within the Charley River A-1. A-2, A-3. 6-1, 8-2, 8-3, C-I, and C-2 1:63.360-scale quadrangles. Sources of information for the campilation are mainly published reports of the U.S. Geological Survey, as well as unpublished fieldnotes. maps. and fossil reports of USGS workers conducting geologic studies in the area. The fossil data in the table are listed chronologfcally, by collector, according to when the fossils were collected. This information includes, where available, map number. geologic map unit, collector's field number, USGS collection number, fossil list, and fossil age designation. Sources of information and names of paleontologists Hho identified fossils are keyed with superscripts and cited at the end of the table. Reports for most of the collections that have been assigned a USGS collection number are on file at the U.S. National Museum of Natural History in Washington. D.C. The fossil lists are reproduced as originally prepared by the paleontologists indicated. However, many of the older collections have been restudied by later workers, and because of improved taxonomic and stratigraphic frameworks, restudy has resulted in revised identification, correlation, and(or) age designation for many collections. Consequently, care should be taken in using the appraisals of early workers and most attention should be given to the more current reports and publications.

  • The Triassic Marine Biota of Eastern Indonesia and Its Interregional and Global Correlation: a Review
    Jurnal Geologi Indonesia, Vol. 5 No. 1 Maret 2010: 31-47 The Triassic Marine Biota of Eastern Indonesia and its Interregional and Global Correlation: A Review F. HASIBUAN Geological Survey Institute Jln. Diponegoro 57, Bandung 40122, Indonesia ABSTRACT The interregional and global correlation of the Triassic biota of Indonesia was based on the review of previous workers and the author himself. Scythian Epoch (Early Triassic) in Timor is subdivided into Early Scythian with Ophiceras demisso, Meekoceras sp., Pseudomonotis subaurita, Gervillia subpannonica, and Myophoria sp., whilst Late Scythian is indicated by the presence of Owenites egrediens and Sibirites sp. The presence of Anisian Stage (Middle Triassic) in Misool is indicated by ammonite Beyrichites and bivalve Daonella lilintana. In Timor, this stage is pointed out by the presence of Joannites cymbiformis, Monophyl- lites wengensis, Protrachyceras archaelus, Daonella indica, Tracyceras cf. aon, Brochidium timorense, and Lima subpunctatoides. Terebellina mackayi found above Beyrichites-bearing bed in Misool has an age range from Anisian to Ladinian. It is concluded that the boundary between Anisian and Ladinian lies between beds with Beyrichites and Terebellina mackayi. Early Carnian Stage (Late Triassic) in Timor is indicated by the presence of Joanites cymbiformis, Waldhausenites sp., Miltites sp., and Halogyra cipitiensis; whereas Late Carnian is indicated by the presence of Cladicites crassestriatus and Tropites subbulatus. The presence of Halobia verbeeki, Pinacoceras parma, Neobetites sp., Parabetites sp., Malayites sp., Amarassites sp., and Halorites sp., indicates the Early Norian Stage, whilst the presence of Cladiscites tornatus, Cyrtopleurits malayicus, and Trachypleuraspidites sp. implies the Late Norian. The Rhaetian Stage in Timor contains Choristoceras indoaustralicum, whereas in Misool it contains Choristoceras sp.

  • The Ammonoid Recovery After the End−Permian Mass Extinction: Evidence from the Iran−Transcaucasia Area, Siberia, Primorye, and Kazakhstan
    The ammonoid recovery after the end−Permian mass extinction: Evidence from the Iran−Transcaucasia area, Siberia, Primorye, and Kazakhstan YURI D. ZAKHAROV and NASRIN MOUSSAVI ABNAVI Zakharov, Y.D. and Moussavi Abnavi, N. 2013. The ammonoid recovery after the end−Permian mass extinction: Evidence from the Iran−Transcaucasia area, Siberia, Primorye, and Kazakhstan. Acta Palaeontologica Polonica 58 (1): 127–147. Investigations of the Upper Permian strata in the Iran−Transcaucasia resulted in identification of 32 ammonoid genera. The majority of ammonoids in this collection belong to the order Ceratitida (75%). Among Dzhulfian ceratitid ammonoids representatives of the family Araxoceratidae (Otoceratoidea) are most abundant. The assemblage structure changed radically during latest Permian (Dorashamian) time, bringing a domination of the family Dzhulfitidae. The Induan (Lower Triassic) succession in the Verkhoyansk area provided a few groups of ammonoids which are Palaeozoic in type: families Episageceratidae (Episageceras), Xenodiscidae (Aldanoceras and Metophiceras), and Dzhulfitidae (Tompophiceras) and superfamily Otoceratoidea (Otoceras and Vavilovites). It demonstrates the survival of ammonoids belonging to these groups the Permian–Triassic (P–T) boundary extinction event and their quick migration to the vast ar− eas of higher latitudes (together with some representatives of the Mesozoic−type families). Induan–Olenekian ammonoid successions in South Primorye, Mangyshlak, and Arctic Siberia illustrate the high rate of Early Triassic ammonoid recov− ery in both the Tethys and the Boreal realm. New ammonoid taxa are described: Proptychitina subordo nov., Ussuritina subordo nov., Subbalhaeceras shigetai gen. and sp. nov. (Flemingitidae), Mesohedenstroemia olgae sp. nov. (Heden− strormiidae), and Inyoites sedini sp. nov. (Inyoitidae). Key words: Ammonoidea, recovery, Permian, Triassic, Russia, Azerbaijan, Kazakhstan, Iran.
