      Abstract: Early Maastrichtian erect bryozoans from western Kazakhstan, with descriptions of two new species and the comparative internal morphology of some cheilostome generaKoromyslova, Anna V.; Taylor, Paul D.; Pakhnevich, Alexey V.
      Neues Jahrbuch für Geologie und Paläontologie - Abhandlungen, (2021), p. 235 - 262 Erect cyclostome and cheilostome bryozoans are described for the first time from the lower Maastrichtian of the Aktolagay Plateau in western Kazakhstan. The studied bryozoan assemblage includes the cyclostomes Meliceritites cf. dentiferus Viskova and ?Reteporidea sp., and the cheilostomes Rhagasostoma cf. saltans (Brydone), Acoscinopleura beniamovski sp. nov. and Escharifora? invisibilia sp. nov. A combination of scanning electron microscopy and X-ray microtomography were used to characterize their external and internal morphologies. The comparative morphology of the studied cheilostome genera is discussed. The bryozoans belong to genera ubiquitous in the Maastrichtian of Europe and Central Asia. Moreover, R. cf. saltans, A. beniamovski sp. nov. and E.? invisibilia sp. nov. have extensive geographical distributions.

      Abstract: Source rock evaluation and thermal maturity the Upper Cretaceous rocks in Abu El Gharadig Basin, Egypt: Insights to the petroleum systemAbd El Gawad, Esam A.; Makled, Walid A.; Mousa, Ahmed S.; El Hariri, Tarek Y.; Mousa, Doaa A.; Hamed, Tamer E.
      Neues Jahrbuch für Geologie und Paläontologie - Abhandlungen, (2021), p. 263 - 297 The Upper Cretaceous rocks of the Abu Roash and Bahariya formations are among of earliest recorded source rocks in the Abu El Gharadig Basin the Western Desert of Egypt. In the present study, samples from three wells have been studied and analyzed by the organic geochemistry and organic petrography to determine the origin of the organic matter and their thermal maturity to evaluate their hydrocarbon generation potentiality. The determined source rocks are placed in a model based on the seismic data to build up a petroleum system. The Bahariya Formation and the members of the Abu Roash Formation are found to contain fair to good quantities of organic matter in Ag‑4 well, and specifically reach to very good in the F Member in Spyglass‑1X and AG121‑X. The organic matter was subjected to microscopic examination using transmitted and reflected white and blue lights. Five palynofacies types were determined by the statistical cluster analysis of organic matter. These palynofacies types are sorted out based on the proximal–distal trend and they include the distal humid dysoxic palynofacies type A, highly proximal arid oxic palynofacies type B, proximal humid oxic palynofacies type C, distal anoxic palynofacies type D and distal humid suboxic palynofacies type E. These palynofacies types contain different type of kerogen in variable amounts. The oil prone kerogen type II that is composed mainly of AOM with distinguishable fluorescence color and inclusions in addition to cuticles and palynomorphs are found to be dominant in the palynofacies distal anoxic palynofacies type D and distal humid suboxic palynofacies type E. Other gas prone kerogen type III and mixed type II/III are found in the other palynofacies type. The pyrolysis analysis by the Rock Eval and gas chromatography confirmed the microscopic results with type II, type III and Mixed II/III, with highest quality organic matter in the Abu Roash F Member. The studied section includes significant levels with oil prone materials. The organic conversions levels remained low despite thermally mature rocks in the Abu Roash G, F, E, D and C members and the Bahariya Formation as indicated by the vitrinite reflectance, fluorescence and Tmax  data. The burial history models revealed onset of oil generation between 18 and 22 Ma in the Miocene. An active petroleum system is based on the determined source rocks in the succession of the Abu Roash and Bahariya formations, where the hydrocarbon migrated and accumulated through the fault zones as illustrated by seismic 3D model.

  • A new Ophiopsiformes (Halecomorphi, Neopterygii) from the Upper Jurassic
           of Nusplingen (Germany) and a comparison of Kimmeridgian Ophiopsiformes
           from Nusplingen with Tithonian taxa from the Solnhofen Archipelago

      Abstract: A new Ophiopsiformes (Halecomorphi, Neopterygii) from the Upper Jurassic of Nusplingen (Germany) and a comparison of Kimmeridgian Ophiopsiformes from Nusplingen with Tithonian taxa from the Solnhofen ArchipelagoEbert, Martin
      Neues Jahrbuch für Geologie und Paläontologie - Abhandlungen, (2021), p. 299 - 329 Fossil fish are known from almost all of the Upper Jurassic Plattenkalk sites, and specimens of the Halecomorphi, to which the here described fishes belong, are known from all fossil-bearing Plattenkalk localities of the Upper Jurassic. The Kimmeridgian locality Nusplingen (Baden-Württemberg, Germany), which is the focus of this article, is one of the stratigraphically oldest of the Upper Jurassic Plattenkalk localities in Southern Germany and with currently eight species known to the author among the localities with the highest diversity. Almost all localities of the Solnhofen Archipelago (Bavaria, Germany) featuring Ophiopsiformes (currently 12 accepted species) are of Tithonian age and somewhat younger than Nusplingen. Thus, it is not surprising that there are slight differences between the otherwise very similar taxa of Nusplingen and the Plattenkalk basins of the Solnhofen Archipelago. In this paper, the new species Elongofuro augustilgi is described from the Nusplingen Plattenkalk. The new species is assigned to the genus Elongofuro mainly by the following unique combination of features: a mosaic of multiple suborbitals (more than 12); all exterior cranial bones ornamented; high number of principal caudal fin rays (approximately 29); 52–59 vertical scale rows from postcleithra to hinge line. The species from the Solnhofen Archipelago currently known as ‘Furo’ angustus is recognized in Nusplingen as well. ʻFuro’ aldingeri, occurring in Nusplingen and Erpfingen (both Baden-Württemberg, Germany) also seems to be present in the Solnhofen Archipelago. However, due to slight differences, the specimen in question is here termed as ʻFuro’ cf. aldingeri. The differences in the fauna of the individual Plattenkalk basins and the small differences between similar taxa are subject to ongoing research.

  • Plant macrofossils from the Rhaetian of Einberg near Coburg (Bavaria,
           Germany). Part 1. Ferns, fern allies and seed ferns

      Abstract: Plant macrofossils from the Rhaetian of Einberg near Coburg (Bavaria, Germany). Part 1. Ferns, fern allies and seed fernsVan Konijnenburg-van Cittert, Johanna H.A.; Schmeißner, Stefan; Dütsch, Günter; Kustatscher, Evelyn; Pott, Christian
      Neues Jahrbuch für Geologie und Paläontologie - Abhandlungen, (2021), p. 331 - 353 A macrofossil plant assemblage obtained from Rhaetian strata of a quarry near Einberg (Franconia, Germany) produced a diverse array of sphenophyte, fern and seed fern remains. These are described by means of macromorphology and epidermal anatomy. In total, two horsetails were identified (a Neocalamites and an Equisetites species each). Ferns are represented by four species in three families; Osmundaceae with two Todites species, Matoniaceae with one Phlebopteris species, and Dipteridaceae with one Clathropteris species. Incurled fern fronds have been attributed to the fossil-genus Spiropteris and fern rhizomes are recorded as well. Three seed fern taxa have been identified, viz. a species of Lepidopteris with its male and female reproductive organs (Peltaspermales), a species of Scytophyllum (Peltaspermales) and a species of Pachypteris (Umkomasiales). Moreover, a few fructifications have been recorded that have been tentatively assigned to the genus Kirchmuellia. A comparison between the flora from Einberg with the Rhaetian floras of the nearby localities Wüstenwelsberg, Heilgersdorf and Kipfendorf reveals distinct local differences in the sphenophyte, fern and seed fern portion of the respective floras; this is referred to ecological differences. Moreover, brief comparisons with Rhaetian floras from adjacent European areas were made.

  • Large mammals (Proboscidea, Perissodactyla) from the late Miocene Burel
           Basin in West Bulgaria

      Abstract: Large mammals (Proboscidea, Perissodactyla) from the late Miocene Burel Basin in West BulgariaBöhme, Madelaine; Kampouridis, Panagiotis; Markov, Georgi N.; Hristova, Latinka; Spassov, Nikolai
      Neues Jahrbuch für Geologie und Paläontologie - Abhandlungen, (2021), p. 117 - 129 The Neogene Burel Basin in the Western Srednogorje region of the Balkans provides rare fossil large mammals, which have importance for mammalian evolution and faunal chronology at the Miocene-Pliocene transition of the Balkan Peninsula. Here we report on new, and review published, proboscideans and perissodactyls from the Kaisiinitsa and Tranerska formations. We identify the following taxa: Anancus ? lehmanni, ʻMammut’ sp., Deinotherium proavum, Dihoplus sp., Tapirus arvernensis, and Hipparion crassum. Our biochronologic interpretation is consistent with a late Turolian (MN13) age of both formations and in support of a correlation to the Pontian stage. However, we admit that numerical dating of the Burel section is needed by future research using magnetostratigraphy and geochronology.

      Neues Jahrbuch für Geologie und Paläontologie - Abhandlungen, (2021), p. 131 - 138 A new species of the primitive crab genus Bucculentum Schweitzer & Feldmann, 2009 is recorded from the Mörnsheim Formation (Upper Jurassic, lower Tithonian, hybonotum ammonite Zone) at Mühlheim, near Solnhofen. The new species is one of the largest members of the genus known to date. It can be distinguished from congeners in particular on the basis of carapace outline, placement of spines and shape of the branchial region and carapace grooves.

      Abstract: A new species of plant louse from mid-Tertiary Dominican amber (Hemiptera: Psylloidea) with adjacent plant leavesPoinar Jr., George; Brown, Alex E.
      Neues Jahrbuch für Geologie und Paläontologie - Abhandlungen, (2021), p. 139 - 146 A new species of plant-louse from Dominican amber is described as Tuthillia maculosa sp. nov. (Hemiptera: Sternorrhyncha: Psylloidea). Features of the new species are: eight narrow, annulated, antennal flagellomeres of variable length with the first flagellomere longest, fore wings with a Rs-M crossvein, long claval suture, elongate pterostigma, veins R, M and Cu each with a single branch and mottled forewings. Hind wing long, expanded apically, with well-developed Rs and one branched M vein. Tarsi with two unequal segments, the apical tarsal segment longer than the basal. Diagonal spur arising from tip of apical tarsomere extends between well-developed, widely diverging pulvilli. The distribution of Rs-M crossveins in extant and extinct plant lice dating back to the Permian is documented. The plant-louse may have been feeding on adjacent plant leaves.

      Abstract: Revision of Tornoceras typus (Sandberger & Sandberger, 1851) – an iconic Devonian ammonoid of a clade with slow morphological evolutionKorn, Dieter
      Neues Jahrbuch für Geologie und Paläontologie - Abhandlungen, (2021), p. 147 - 167 The ammonoid species Tornoceras typus (Sandberger & Sandberger, 1851) (middle Frasnian, Late Devonian) is revised on the basis of the original material and material from the eastern margin of the Rhenish Mountains. The detailed investigation of the conch form and its ontogeny requires a more restrictive species diagnosis; a separation from morphologically similar forms from other stratigraphic units is necessary. Material from the Rhenish Mountains formerly attributed to Tornoceras typus (or “Tornoceras simplex”) are newly described here as Tornoceras vretterense n. sp. (Givetian) and Tornoceras fundibulum n. sp. (early Famennian). In addition, the new tornoceratid species Domanikoceras martenbergense n. sp. (middle Frasnian) and Linguatornoceras asbeckense n. sp. (late Frasnian) are described. The morphological and stratigraphic data suggest that both Tornoceras and Linguatornoceras survived the Kellwasser crisis.

  • The stratigraphic position of Homo steinheimensis (late Middle
           Pleistocene, SW Germany)

      Abstract: The stratigraphic position of Homo steinheimensis (late Middle Pleistocene, SW Germany)Bloos, Gert
      Neues Jahrbuch für Geologie und Paläontologie - Abhandlungen, (2021), p. 169 - 208 The stratigraphic position of the time of Homo steinheimensis can be best recognized by its relation to the terrace of the Elsterian (= Mindelian in traditional understanding) cold stage (MIS 12) in the adjoining Neckar valley. On the surface of the Elsterian terrace on either side of the River Neckar at Stuttgart, the 7 m thick Holsteinian travertine (MIS 11) was deposited, thus indicating that the Elsterian gravel was not affected by erosion during the Holsteinian. Interglacials generally were no times of valley cut down in the Neckar region as it is still today. In the initial phase of the subsequent Fuhnian cold stage (MIS 10) strong valley cut down removed the 10 m thick Elsterian gravel almost completely in the Neckar region. Rare exceptions are preserved in protected positions as at Stuttgart-Bad Cannstatt and at Neckarwestheim. Most probably, at Steinheim a basal part of the Elsterian gravel, 3 m thick, is preserved. After the erosion, the Fuhnian terrace was deposited on the now 10 m lower level. On this terrace at Stuttgart sedimentation continued with an up to 26 m thick travertine on the left side of the Neckar. In this time at Steinheim the antiquus gravel was deposited which contained the skull of Homo steinheimensis. Thus, since the antiquus gravel was not deposited earlier than after the Elsterian terrace was removed, this gravel represents the warm stage following the Holsteinian (MIS 9). An additional support of that conclusion is the occurrence of Mammuthus trogontherii fraasi above the antiquus gravel what refers to the stratigraphy of the Saale-Unstrut region (Thuringia and Saxony-Anhalt, central Germany). The absolute age of the skull is estimated at 330 ka B.P. – based on the age of MIS 9 in the MIS time scale and adjusted to the late part of the climatic optimum where the skull was found. A glance on the stratigraphic position of the similar human skull of Swanscombe (UK) ends this contribution.

      Abstract: Oravaichnium oualimehadjensis, a new possible bivalve repichnion from the Upper Jurassic Argiles de Saïda Formation (middle Oxfordian, Saïda Mounts, NW Algeria)Nadir Naimi, Mohammed; Cherif, Amine
      Neues Jahrbuch für Geologie und Paläontologie - Abhandlungen, (2021), p. 209 - 220 A new ichnotaxon, Oravaichnium oualimehadjensis isp. nov., is here erected from greenish claystones interbedded by sandstone beds of the upper Jurassic (middle Oxfordian) Argiles de Saïda Formation from the Beni Berdaa section (Takhemaret area, Saïda Mounts, NW Algeria). It is a simple, hypichnial, smooth continuous burrows, which exhibit a box shape in cross section. O. oualimehadjensis is interpreted as predepositional trace fossil, produced by the locomotion activity of wedge-foot bivalves in a storm dominated shallow-marine environment. Oravaichnium oualimehadjensis constitutes the second ichnospecies of the rare ichnogenus Oravaichnium Plička & Uhrová, 1990 after O. hrabei, the type ichnospecies, described from Eocene flysch deposits of the Carpathians.
