Opis:
We describe an additional fragmentary upper molar and the first lower molar known of Monotrematum sudamericanum, the oldest Cenozoic (Paleocene) monotreme. Comparisons suggest that the monotreme evolution passed through a stage in which their molars were “pseudo−triangulate”, without a true trigonid, and that the monotreme pseudo−triangulate pattern did not arise through rotation of the primary molar cusps. Monotreme lower molars lack a talonid, and consequently there is no basin with facets produced by the wearing action of a “protocone”; a cristid obliqua connecting the “talonid“ to the “trigonid” is also absent. We hypothesize that acquisition of the molar pattern seen in Steropodon galmani (Early Cretaceous, Albian) followed a process similar to that already postulated for docodonts (Docodon in Laurasia, Reigitherium in the South American sector of Gondwana) and, probably, in the gondwanathere Ferugliotherium.

Opis:
New mammalian fossils at Cochrane 2, Paskapoo Formation, Alberta, Canada, document five new species and two new combinations: Ptilodus gnomus sp.nov.and Baiotomeus russelli sp.nov.(Multituberculata), Thryptacodon orthogonius comb.nov.and Litomylus grandaletes sp.nov.(“Condylarthra”), Pararyctes rutherfordi sp.nov., Bessoecetor septentrionalis comb.nov., and Paleotomus junior sp.nov.(Eutheria incertae sedis).These new taxa supplement a taxonomically diverse Cochrane 2 local fauna, representing one of the most species rich Paleocene mammalian localities in the world. An earliest Tiffanian age is estimated for the locality based on the presence of the index taxa Plesiadapis praecursor, Nannodectes intermedius, and Ectocion collinus.The Cochrane 2 local fauna fails to demonstrate a decrease in species number relative to those of late Torrejonian localities from the United States, as would be predicted by current paleoclimate scenarios; the rarity of earliest Tiffanian localities in North America suggests sampling error as a partial explanation for the apparent incongruity.

Opis:
A new genus and species belonging to Dyrosauridae, Arambourgisuchus khouribgaensis, from the Thanetian (Palaeocene) of Morocco, is erected. Two more or less complete skulls and three mandibular fragments enable a reconstruction of the anatomical characteristics of this species. Dyrosaurid systematics is mainly based on mandibular characters. The comparison of this new material with several dyrosaurid species previously known provides new systematic data for this group. The width of the interfenestral bar, the shape and development of the occipital tuberosities and the shape of the supraoccipital and the basioccipital are of particular importance. A phylogenetic analysis of the dyrosaurids provides an outline of the relationships between the best known species. Chenanisuchus lateroculi is the most primitive dyrosaurid. Sokotosuchus ianwilsoni and Phosphatosaurus gavialoidesform a clade, more closely related to other dyrosaurids than to Chenanisuchus lateroculi. The relationships between Arambourgisuchus, Rhabdognathus, Congosaurus, and Hyposaurus are unclear, and the two latter taxa remain too poorly known to provide an uncontested phylogenetic result. The dyrosaurids are known from nearly all continents. The phylogenetic results suggest a North African range for basal members, and the wide distribution of Rhabdognathus and Hyposaurus confirms the possibility of transoceanic dispersal of these taxa. Unfortunately, many dyrosaurids are insufficiently known to be included in the analysis, and the present analysis considers mainly African forms. A better knowledge and the inclusion of other taxa from other geographic regions should significantly improve and modify the hypothesis.

Opis:
Nyctitheriids are primitive insectivores that were relatively abundant and diverse in North America and Europe during the middle Paleocene through to the middle Oligocene. The nyctitheriids from Asia are poorly known and show several distinctive characters. Here we describe the late Paleocene Asionyctia guoi gen. et sp. nov., the first fairly well known Asian nyctitheriid, from the Subeng locality near the city of Erlianhot (Erenhot) in Inner Mongolia, China. Among its most conspicuous features are the paraconid positioned high on p4, the rather primitive morphology and size of p3, the premolariform P4/p4 and the transverse upper molars with a small, straight postcingulum. Except for the paraconid positioned high on p4, these combined features are also present in other Asian nyctitheriids, but absent in North American or European forms. We performed a cladistic analysis, based on a set of 20 dental characters, to resolve higher−level phylogenetic relations within Nyctitheriidae. The strict consensus tree groups all Asian forms in a single clade, for which we propose the rank of a subfamily and the name Asionyctiinae subfam. nov. Within Nyctitheriidae, a semimolariform P4/p4, as in Leptacodon tener, is considered primitive, and we consider the morphologically simplified P4/p4 of Asionyctiinae derived within Nyctitheriidae. Asionyctiinae can be derived from an American, primitive Leptacodon−like ancestor migrating into Asia, with the reduction of P4/p4 occurring on the Asian continent. Considering the derived morphology and the relatively high diversity of Asionyctiinae during the Asian late Paleocene, and the inferred conservative nature of the family Nyctitheriidae, we suggest an early Tiffanian time for the migration of nyctitheriids into Asia.

Opis:
Originally designated by Dollo in 1907, the holotype of Eosuchus lerichei has never been carefully described but simply cited and compared in a number of papers. This work is an attempt to fill this gap and to place this taxon in a cladistic phylogenetic context. E. lerichei can be considered a valid basal gavialoid from late Paleocene of North Western Europe, sharing the presence of extremely enlarged foramina aerea on quadrates with the coeval Eosuchus minor from eastern North America (formerly described as Gavialis minor). These two species can be considered sister taxa and, for priority reason, they should be both ascribed to genus Eosuchus. The results of the cladistic analysis show that the European species possess characters that can be considered as slightly derived if compared to those of its American relative, suggesting an eastward dispersion from North America before the Paleocene–Eocene boundary and before the full opening of the Atlantic Ocean or local evolution from a basal gavialoid stock similar to E. minor. Both species of Eosuchus come from marine outcrops and represent a further evidence for the salt−water tolerance of the earliest stages of Gavialoidea evolutionary history. Despite the present endemicity of the only living gharial, Gavialis gangeticus, the historical biogeography of gavialoids shows a lost global distribution and reveals several transoceanic dispersals.

Opis:
W pracy opisano debryty kohezyjne warstw istebniańskich zachodniej części jednostki śląskiej Karpat zewnętrznych. Przedstawiona litofacja reprezentuje utwory silikoklastyczne, zbudowane z mieszaniny mułowo-piaskowego spoiwa i rozproszonego materiału okruchowego frakcji psefitowej. Powstawanie debrytów kohezyjnych związane było z grawitacyjnymi spływami osadu, generowanymi na skłonie basenu sedymentacyjnego przez ruchy masowe. Prezentowane utwory deponowane były w formie fartuchów przez podwodne, kohezyjne spływy rumoszowe. Największy udział miąższościowy debrytów kohezyjnych (12%) stwierdzono w warstwach istebniańskich Beskidu Śląskiego, znaczący udział odnotowano w Beskidzie Małym (7%), a najmniejszy w Beskidzie Morawskim (2%). Z największą częstotliwością opisana litofacja występuje w obrębie piaskowców istebniańskich dolnych, a regułą jest także pojawianie się w stropie łupków istebniańskich dolnych debrytów kohezyjnych z litoklastami o największych rozmiarach. Około 25% opisanych utworów zawierało w składzie fazy rozproszonej materiał egzotykowy (egzotykowe debryty kohezyjne), w których dominowały skały krystaliczne, przede wszystkim gnejsy, łupki krystaliczne i granitoidy. Wśród znacznie rzadziej obserwowanych egzotyków skał osadowych stwierdzono wyraźne zwiększanie się z zachodu na wschód udziału różnego rodzaju wapieni
Cohesive debrites of the Istebna Beds occur within the western part of the Silesian Unit of the Outer Flysch Carpathians. The lithofacies described represents siliciclastic deposits consisting of mud-sandy matrix and scattered, psephite-size clasts. The cohesive debrites originated from sediment gravity flows that were generated on the slope of sedimentary basin by mass-movements and were deposed as aprons by submarine, cohesive debris flows. The highest content of the cohesive debrites (12% of the succession thickness) has been recorded within the Istebna Beds of the Silesian Beskid Mts, the medium in the Beskid Mały Mts (7%) and the lowest within the Moravian Beskid Mts (2%). Most frequently the lithofacies presented occurs within the Lower Istebna Sandstones, while the cohesive debrites with the biggest lithoclasts occur within the top part of the Lower Istebna Shales. The exotic material with dominating crystalline rocks, mostly gneisses, schists and granitoids, makes up 25% of the described deposits (exotic cohesive debrites). Various types of limestones prevail among much rarer clasts of sedimentary rocks and the amount of the limestones distinctly increases going to the east

Opis:
The aim of this work is to present geological structure of the Krynica Subunit of the Magura Nappe in southern part of the Gorce and Beskid Sądecki Mountains and along the Pieniny Klippen Belt (PKB). Formal lithostratigraphic units were distinguished on the basis of mapping. The lithostratigraphic units are the age of Middle Paleocene - Middle Eocene age. Flysch deposits were classified as the Szczawnica Formation with the Życzanów Member, Zarzecze Formation and Piwniczna Member of the Magura Formation in the investigated area. Strike-slip faults and faulted formations complicate the geological structure of the described region. The creation some of these faults is connected with andesite intrusions. Strong faulted strata occurs in the southern part of the region along the overthrust of the Pieniny Klippen Belt on the Magura Nappe. The contact line between the Pieniny Klippen Belt and Paleogene of the Magura Nappe is heterogeneous. The evidences of it are outcrops of klippen, which occur within the Szczawnica Formation and the Zarzecze Formation
Główny założeniem niniejszej pracy jest zaprezentowanie budowy geologicznej podjednostki krynickiej płaszczowiny magurskiej w południowej części Gorców i Beskidu Sądeckiego oraz na kontakcie z pienińskim pasem skałkowym. Wydzielone na podstawie badań kartograficznych formalne jednostki litostratygraficzne obejmują osady od środkowego paleocenu do środkowego eocenu. Na badanym obszarze osady fliszowe zostały sklasyfikowane jako formacja szczawnicka z ogniwem z Życzanowa, formacja z Zarzecza oraz ogniwo piaskowców z Piwnicznej formacji magurskiej. Budowę geologiczną opisywanego obszaru komplikują liczne uskoki o charakterze przesuwczym oraz sfałdowane utwory fliszowe. Powstanie części tych uskoków jest związane z intruzjami andezytowymi. Mocno sfałdowane utwory występują w południowej części obszaru wzdłuż nasunięcia pienińskiego pasa skałkowego na płaszczowinę magurską. Linia kontaktu pasa skałkowego z paleogenem magurskim nie jest jednolita. Świadczą o tym wychodnie skałek w obrębie utworów formacji szczawnickiej i formacji z Zarzecza

Opis:
New dental and postcranial remains of the alleged louisinine hyopsodontid “condylarth” Microhyus from the European Paleocene/Eocene transition are described, and prompt a reevaluation of the genus. New specimens belonging to Microhyus musculus from Dormaal (MP7, Belgium) provide the first evidence of the lower dentition of the type species. We describe M. musculus? from Pourcy (MP7, France) and cf. Microhyussp. from Berru (MP6a, France). A rich original assemblage of M. reisi from Silveirinha (MP7, Portugal) allows a detailed description of the morphological dental variation within that species. Well−preserved astragali and calcanei from Silveirinha can be confidently attributed to Microhyus reisi. Functional analysis of these elements suggests that Microhyus was a terrestrial mammal capable of rapid running or jumping. The pedal morphology of Microhyus is very similar to that of Paschatherium. These louisinines share some derived characters with the hyopsodontids Apheliscus and Haplomylus (e.g., the occurrence of a cotylar fossa on the astragalus) but they differ from Hyopsodus. Therefore, in view of the pedal morphology alone, the hyopsodontids may be polyphyletic. Given the dental similarities between Microhyus and the early representatives of the order Macroscelidea, we compared the tarsal morphology of louisinines with that of modern macroscelidids (Paleogene tarsal remains are currently unknown for this group). Macroscelidids and louisinines present some similarities in their astragalar morphology; however, the macroscelidid astragalus appears to be too specialized to be compared with that of Microhyus and Paschatherium.

Opis:
The phylogenetic relationships of the Paleocene crocodylian Akanthosuchus langstoni are assessed using published data matrices and morphological data from the holotype and referred specimens. Cladistic analyses indicate that Akanthosuchus is unequivocally nested within Alligatoroidea. Weak support from a majority rule consensus tree indicates that Akanthosuchus may be more closely allied with alligatorines than with caimanines, but in the strict consensus tree these relationships remain ambiguous. There is no evidence from phylogenetic analyses to support the hypothesis that Akanthosuchus represents the postcrania of the Paleocene crocodylians Navajosuchus or Ceratosuchus. Growth marks observed in histological sections of osteoderms of the holotype of Akanthosuchus langstoni indicate that it was at least eight years old at the time of death. Although the individual may not have been fully mature at the time of death, lineage dwarfism cannot be ruled out as a possible reason for its relatively small size.

Opis:
Seven high-quality reflection-seismic lines, calibrated by wells, were interpreted in an effort to assess the timing of inversion and the structural configuration of the Pomeranian and Kuiavian segments of theMid-Polish Trough. Seismostratigraphic analyses of the Upper Cretaceous successions imaged by these seismic lines in the NE and SW marginal troughs of the Mid-Polish Swell document important along-strike stratigraphic and structural changes. Thickness variations of the Upper Cretaceous series, combined with the development of erosional unconformities and associated tectonic deformations indicate that inversion movements commenced during the late Turonian and intermittently persisted into the Maastrichtian and Paleocene. Earliest inversion movements were focused on the margins of the Mid-Polish Trough where Mesozoic sequences are decoupled from the sub-Zechstein series by Zechstein salts. Whereas the NE margin of theMid-Polish Trough is devoid of compressionally reactivated salt structures, its SWmargin is characterized by strong inversion- related salt tectonics. Progressive inversion of the axial parts of the Mid-Polish Trough was accompanied by uplift of its pre-Zechstein floor to and above the level of flanking, non-inverted areas, and by deep truncation ofMesozoic series across the culmination of the evolving Mid-Polish Swell. Inversion movements ceased towards the end of the Paleocene, as evidenced by the burial of the Mid-Polish Swell beneath essentially flat lying Eocene and younger series. Turonian-Paleocene inversion of the Mid-Polish Trough is coeval with the inversion of the Bohemian Massif, the North German Basin and the Sorgenfrei-Tornquist Zone. Inversion of the Mid-Polish Trough is considered to have been controlled mainly by compressional intraplate stresses that built up in the Carpathian foreland during the collision of the Inner Carpathian orogenic wedge with the European passivemargin, attesting to their increasing mechanical coupling, commencing during the Turonian. These stresses relaxed, however, with the end-Paleocene onset of imbrication of the Outer Carpathian domain, reflecting decoupling of the Carpathian orogenic wedge from its foreland.

Opis:
The Paleocene–Eocene boundary is of particular importance for the evolution of mammals and the poorly known Asian mammal faunas from this period have received much attention. The late Paleocene Subeng site in Inner Mongolia (China) has come under study only recently, and here we present the first complete description of its mammal fauna. Two new species are described, the neoplagiaulacid multituberculate Mesodmops tenuis sp. nov. and the praolestine nyctitheriid Bumbanius ningi sp. nov., representing stratigraphic range extensions of the respective genera into the Paleocene. Previously unknown parts of the dentition are described here for the eurymylid Eomylus bayanulanensis, the sarcodontid Hyracolestes ermineus, the cimolestid Tsaganius ambiguus, the carpolestid Subengius mengi, as well as the femur of the mesonychid Dissacus serratus. For most taxa, the new specimens from Subeng provide new phylogenetic and/or biostratigraphic information. We confirm the inclusion of Hyracolestesin the Sarcodontinae and elevate this group to the rank of family, the Sarcodontidae, separate from Micropternodontidae. In the case of Subengius mengi an updated cladistic analysis of carpolestids supports the hypothesis that Subengius is derived from an evolved Elphidotarsius−like ancestor in the early to middle Tiffanian of North America. A total of 17 species is identified, including well−known biostratigraphic markers for the late Paleocene Gashatan Asian Land Mammal Age such as Lambdopsalis bulla, Prionessus sp., Palaeostylops iturus, Pseudictops lophiodon, Tribosphenomys minutus, and Dissacus serratus. We propose that the Gashatan faunas are less endemic than previously thought, and result from a significant exchange with North American faunas from the late Paleocene.

Vastan Lignite Mine in southeastern Gujarat, India, produces the oldest known Cenozoic land−mammals and the only early Eocene continental vertebrate fauna known from India (e.g., Bajpai et al. 2005; Rana et al. 2005, 2008; Rose et al. 2006, 2008, 2009; Smith et al. 2007; Rage et al. 2008). The fauna comes from the Cambay Shale Formation and has been dated as middle Ypresian (~52 Ma, early Cuisian) based on a common nummulitid foraminiferan from about 15 m above the vertebrate−producing layer (Sahni et al. 2006; Rana et al. 2008). However, a recent study of dinoflagellate cysts from the section suggests that the deposits may be as old as 54–55 Ma (Garg et al. 2008). Although some elements of the fauna, such as anthracobunids and lagomorphs, have Asian affinities, a surprising number of taxa among the snakes, bats, insectivores, primates, rodents, and artiodactyls appear to be most closely related to early Eocene European or North American taxa. This may simply reflect the poor state of knowledge of contemporary south Asian vertebrate faunas; alternatively, it might be evidence of previously unsuspected early Eocene faunal exchange between Europe and southwest Asia. We report here two teeth of a tillodont from Vastan Mine, which constitute the first record of the mammalian order Tillodontia known from India. Despite the much greater generic diversity of tillodonts in Asia than elsewhere, the Vastan tillodont shows clear affinities with Euramerican esthonychines.

Opis:
The paper presents the detailed plate tectonic, paleogeographic, paleoenvironment and plaeolithofacies maps for seven Cenozoic time intervals. Thirty five maps, generated using PLATES and PALEOMAP programs, contain information about plate tectonics, paleoenvironment, and paleolithofacies during Paleocene, Eocene, Oligocene, Miocene and Pliocene, time slices. The spatial reconstruction of basin architectures during their origin, expansion, closure and inversion as well as the dynamic of intrabasinal ridges were obtained by palinspastic modeling. This modeling utilized paleomagnetic data and stratigraphic-facies analysis of basins and ridges. Information contained within global and regional papers were selected and posted on the maps. The detailed paleoenvironment and plaeolithofacies zones were distinguished within the basins. The paleogeographic maps illustrate the geodynamic evolution of Earth from Late Cretaceous to Neogene, spreading and origin of new oceans, oceans closing, collisions, continents accretion and origin of new supercontinents.
Artykuł przedstawia szczegółowe mapy paleogeograficzne dla siedmiu przedziałów czasowych w obrębie kenozoiku. Trzydzieści pięć map, skonstruowanych przy użyciu programów PLATES i PALEOMAP, zawiera informacje dotyczące tektoniki płyt, paleośrodowiska i paleolitofacji w czasie paleocenu, eocenu, oligocenu, miocenu i pliocenu. Przestrzenną rekonstrukcję architektury basenów w okresie ich powstawania, ekspansji, zamykania i inwersji oraz analizę dynamiki grzbietów śródbasenowych uzyskano, wykonując modelowanie palinspastyczne, przy uwzględnieniu badań paleomagnetycznych oraz analizy stratygraficzno-facjalnej basenów i rozdzielających je grzbietów. Informacje zawarte w szeregu globalnych i regionalnych prac zostały wyselekcjonowane i naniesione na mapy. W obrębie basenów wydzielono poszczególne strefy paleośrodowiskowe i paleolitofacjalne. Mapy paleogeograficzne ilustrują geodynamiczną ewolucję Ziemi od późnej kredy po neogen, rozrost (spreding) i tworzenie się oceanów, zamykanie się oceanów, kolizje, łączenie się kontynentów i tworzenie się nowych superkontynentów.
