Forty species are distinguished, including a new genus, seven new species and thirteen unnamed ones. The ammonites are divided into two assemblages, both recognizable at Gebel El-Minshera and at Makhtesh Hatira, whereas at Gebel Maghara, only the Upper Assemblage occurs. Both assemblages are attributed to the Upper Callovian; the Upper Assemblage belongs to the Lamberti Zone and part of the Lower possibly ranges into the upper part of the earlier Athleta Zone. Because of the absence of typical cardioceratine ammonites the distinction of the boundary between these two European biozones is quite impossible in southern Tethyan regions. Therefore, both assemblages are attributed to the combined Athleta-Lamberti Zone. Poorly preserved, fragmentary specimens found in the Lower Assemblage which resemble Middle Callovian ammonites are discussed. On the basis of biostratigraphical and lithofacies considerations, a Late Callovian age is attributed to the whole Upper Zohar Formation in the northern Negev, Israel. The Upper Zohar Formation unconformably overlies the Lower Zohar Formation in whose upper part the Meyendorffina b a th on ica Assemblage Zone occurs. This biozone was previously attributed exclusively to the Late Bathonian, but it is herein suggested that it ranges into the Early Callovian. An Upper Bathonian-Upper Callovian unconformity is suggested to occur within the Atash Member of the Upper Dhruma Formation in central Saudi Arabia, based on a revision of the Middle Jurassic ammonites and accompanying faunas recorded from there.

  • The Middle Jurassic of Western and Northern Europe: Its Subdivisions, Geochronology and Correlations
    The Middle Jurassic of western and northern Europe: its subdivisions, geochronology and correlations John H. Callomon The palaeogeographic settings of Denmark and East Greenland during the Middle Jurassic are outlined. They lay in the widespread epicontinental seas that covered much of Europe in the post-Triassic transgression. It was a period of continuing eustatic sea-level rise, with only distant connections to world oceans: to the Pacific, via the narrow Viking Straits between Greenland and Norway and hence the arctic Boreal Sea to the north; and to the subtropical Tethys, via some 1200 km of shelf-seas to the south. The sedimentary history of the region was strongly influenced by two factors: tectonism and climate. Two modes of tectonic movement governed basinal evolution: crustal extension lead- ing to subsidence through rifting, such as in the Viking and Central Grabens of the North Sea; and subcrustal thermal upwelling, leading to domal uplift and the partition of marine basins through emergent physical barriers, as exemplified by the Central North Sea Dome with its associated volcanics. The climatic gradient across the 30º of temperate latitude spanned by the European seas governed biotic diversity and biogeography, finding expression in rock-forming biogenic carbonates that dominate sediments in the south and give way to largely siliciclastic sediments in the north. Geochronology of unrivalled finesse is provided by standard chronostratigraphy based on the biostratigraphy of ammonites. The Middle Jurassic saw the onset of considerable bioprovincial endemisms in these guide-fossils, making it necessary to construct parallel standard zonations for Boreal, Subboreal or NW European and Submediterranean Provinces, of which the NW European zonation provides the primary international standard.

[email protected] Received: 07/10/06 / Accepted: 30/11/06 Abstract A comparative study is made on Callovian to middle Oxfordian sequences along the Northeastern Iberian Chain (E. Spain). In the NW areas, from Veruela-Ricla to Tosos (SW-S of Zaragoza), Callovian deposits are represented by expanded carbonate sequences (mudstone and marls with a variable content in clastics) ranging from early Bullatus to Athleta Biozone. Farther East in the near area of Moneva-Ariño (Sierra de Arcos) and in the area of Calanda (SE of Zaragoza), this stratigraphic interval is represented by a strongly condensed, 2-4 m thick, highly incomplete sequence. Bullatus to early Anceps biozones are partly represented under bioclastic or oolitic packstone facies. The Callovian-Oxfordian transition interval deposits are represented by a decimeter-thick iron- ooid fossiliferous limestone condensed sequence (low values of sedimentation rate) formed by expanded sediments (high values of instant rate of sediment accumulation).

  • A Review of the Classification of Jurassic Aspidoceratid Ammonites – the Superfamily Aspidoceratoidea
    VOLUMINA JURASSICA, 2020, XVIII (1): 47–52 DOI: 10.7306/VJ.18.4 A review of the classification of Jurassic aspidoceratid ammonites – the Superfamily Aspidoceratoidea Horacio PARENT1, Günter SCHWEIGERT2, Armin SCHERZINGER3 Key words: Superfamily Aspidoceratoidea, Aspidoceratidae, Epipeltoceratinae emended, Peltoceratidae, Gregoryceratinae nov. subfam. Abstract. The aspidoceratid ammonites have been traditionally included in the superfamily Perisphinctoidea. However, the basis of this is unclear for they bear unique combinations of characters unknown in typical perisphinctoids: (1) the distinct laevaptychus, (2) stout shells with high growth rate of the whorl section area, (3) prominent ornamentation with tubercles, spines and strong growth lines running in parallel over strong ribs, (4) lack of constrictions, (5) short to very short bodychamber, and (6) sexual dimorphism characterized by minia- turized microconchs and small-sized macroconchs besides the larger ones, including changes of sex during ontogeny in many cases. Considering the uniqueness of these characters we propose herein to raise the family Aspidoceratidae to the rank of a superfamily Aspi- doceratoidea, ranging from the earliest Late Callovian to the Early Berriasian Jacobi Zone. The new superfamily includes two families, Aspidoceratidae (Aspidoceratinae, Euaspidoceratinae, Epipeltoceratinae and Hybonoticeratinae), and Peltoceratidae (Peltoceratinae and Gregoryceratinae nov. subfam.). The highly differentiated features of the aspidoceratoids indicate that their life-histories

Box 1172 Blindern, 0318 Oslo, Norway. 2School of Earth and Environment, University of Leeds, Leeds LS2 9JT, United Kingdom. E-mail corresponding author (Maayke J. Koevoets): [email protected] We describe the invertebrate assemblages in the Middle Jurassic to lowermost Cretaceous of the Agardhfjellet Formation present in the DH2 rock-core material of Central Spitsbergen (Svalbard). Previous studies of the Agardhfjellet Formation do not accurately reflect the distribution of invertebrates throughout the unit as they were limited to sampling discontinuous intervals at outcrop. The rock-core material shows the benthic bivalve fauna to reflect dysoxic, but not anoxic environments for the Oxfordian–Lower Kimmeridgian interval with sporadic monospecific assemblages of epifaunal bivalves, and more favourable conditions in the Volgian, with major increases in abundance and diversity of Hartwellia sp. assemblages. Overall, the new information from cores shows that abundance, diversity and stratigraphic continuity of the fossil record in the Upper Jurassic of Spitsbergen are considerably higher than indicated in outcrop studies. The inferred life positions and feeding habits of the benthic fauna refine our understanding of the depositional environments of the Agardhfjellet Formation. The pattern of occurrence of the bivalve genera is correlated with published studies of Arctic localities in East Greenland and northern Siberia and shows similarities in palaeoecology with the former but not the latter.

  • 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.
