Daza • Aaron M. Bauer Received: 16 May 2017 / Accepted: 17 July 2017 / Published online: 16 January 2018 Ó Swiss Geological Society 2017 Abstract New species of a gecko of the genus Euleptes is described here—E. klembarai. The material comes from the middle Miocene (Astaracian, MN 6) of Slovakia, more precisely from the well-known locality called Zapfe‘s fissure fillings (Devı´nska Nova´ Ves, Bratislava). The fossil material consists of isolated left maxilla, right dentary, right pterygoid and cervical and dorsal vertebrae. The currently known fossil record suggests that isolation of environment of the Zapfe‘s fissure site, created a refugium for the genus Euleptes in Central Europe (today, this taxon still inhabits southern part of Europe and North Africa—E. europea), probably resulting from the island geography of this area during the middle Miocene. The isolation of this territory might have facilitated allopatric speciation.

  • Carnivora from the Late Miocene Love Bone Bed of Florida
    Bull. Fla. Mus. Nat. Hist. (2005) 45(4): 413-434 413 CARNIVORA FROM THE LATE MIOCENE LOVE BONE BED OF FLORIDA Jon A. Baskin1 Eleven genera and twelve species of Carnivora are known from the late Miocene Love Bone Bed Local Fauna, Alachua County, Florida. Taxa from there described in detail for the first time include the canid cf. Urocyon sp., the hemicyonine ursid cf. Plithocyon sp., and the mustelids Leptarctus webbi n. sp., Hoplictis sp., and ?Sthenictis near ?S. lacota. Postcrania of the nimravid Barbourofelis indicate that it had a subdigitigrade posture and most likely stalked and ambushed its prey in dense cover. The postcranial morphology of Nimravides (Felidae) is most similar to the jaguar, Panthera onca. The carnivorans strongly support a latest Clarendonian age assignment for the Love Bone Bed. Although the Love Bone Bed local fauna does show some evidence of endemism at the species level, it demonstrates that by the late Clarendonian, Florida had become part of the Clarendonian chronofauna of the midcontinent, in contrast to the higher endemism present in the early Miocene and in the later Miocene and Pliocene of Florida.

Among Deinotheriidae (Proboscidea), two species, Prodeinotherium bavaricum and Deinotherium giganteum, had previously been identified in the Delémont valley, but never described. A third species, Deinotherium levius, from the locality of Charmoille in Ajoie, is reported herein for the first time in Switzerland. These occurrences are dated from the late early to the early late Miocene, correlating to the European Mammal biozones MN4 to MN9. The study is completed by a discussion on the palaeobiogeography of dinotheres at European scale. Key words: Prodeinotherium, Deinotherium, Bois de Raube formation, Miocene, Jura, Switzerland. Introduction The order of Proboscidea currently regroups large mammals whose common characteristic is the possession of a trunk and tusks. Within the Afrotherians superorder, it has for sister group the Sirenia order (dugongs and manatees).

MADOF, NICHOLAS CHRISTIE-BLICK, AND MARK H. ANDERS 1Chevron Energy Technology Company, Houston, Texas 77002-7308, U.S.A. 2Department of Earth and Environmental Sciences and Lamont-Doherty Earth Observatory of Columbia University, Palisades, New York 10964-8000, U.S.A. e-mail: [email protected] ABSTRACT: The Book Cliffs of eastern Utah and western Colorado have been pivotal in the development of outcrop-based sequence stratigraphic concepts for nonmarine to shallow marine siliciclastic depositional settings. Prior studies in this area, and more generally in the Cretaceous western interior foreland basin of North America, have concluded that nearshore accumulation is controlled for the most part by the interaction between oscillatory eustatic change and longer-term regional patterns of flexural subsidence. New outcrop and subsurface evidence reported here from the eastern Book Cliffs suggests that three-dimensional tectonic tilting at length scales of up to , 50 km (31 mi) and timescales of less than , 200 kyr also strongly influenced sedimentation. Continental ice sheets are thought to have been small at the time. Documented patterns of accumulation are inconsistent with those expected from interactions of eustasy and regional flexure alone. The upper Campanian Cozzette Sandstone Member of the Mount Garfield Formation consists of twelve lithofacies arranged into six lithofacies assemblages, inferred to have been deposited in shallow marine, marginal marine, and nonmarine depositional environments.

[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).

  • Constraints on the Timescale of Animal Evolutionary History
    Palaeontologia Electronica palaeo-electronica.org Constraints on the timescale of animal evolutionary history Michael J. Benton, Philip C.J. Donoghue, Robert J. Asher, Matt Friedman, Thomas J. Near, and Jakob Vinther ABSTRACT Dating the tree of life is a core endeavor in evolutionary biology. Rates of evolution are fundamental to nearly every evolutionary model and process. Rates need dates. There is much debate on the most appropriate and reasonable ways in which to date the tree of life, and recent work has highlighted some confusions and complexities that can be avoided. Whether phylogenetic trees are dated after they have been estab- lished, or as part of the process of tree finding, practitioners need to know which cali- brations to use. We emphasize the importance of identifying crown (not stem) fossils, levels of confidence in their attribution to the crown, current chronostratigraphic preci- sion, the primacy of the host geological formation and asymmetric confidence intervals. Here we present calibrations for 88 key nodes across the phylogeny of animals, rang- ing from the root of Metazoa to the last common ancestor of Homo sapiens. Close attention to detail is constantly required: for example, the classic bird-mammal date (base of crown Amniota) has often been given as 310-315 Ma; the 2014 international time scale indicates a minimum age of 318 Ma.

Swiss J Palaeontol (2020) 139:9 https://doi.org/10.1186/s13358-020-00210-y Swiss Journal of Palaeontology RESEARCH ARTICLE Open Access First record of non-mineralized cephalopod jaws and arm hooks from the latest Cretaceous of Eurytania, Greece Christian Klug1* , Donald Davesne2,3, Dirk Fuchs4 and Thodoris Argyriou5 Abstract Due to the lower fossilization potential of chitin, non-mineralized cephalopod jaws and arm hooks are much more rarely preserved as fossils than the calcitic lower jaws of ammonites or the calcitized jaw apparatuses of nautilids. Here, we report such non-mineralized fossil jaws and arm hooks from pelagic marly limestones of continental Greece. Two of the specimens lie on the same slab and are assigned to the Ammonitina; they represent upper jaws of the aptychus type, which is corroborated by fnds of aptychi. Additionally, one intermediate type and one anaptychus type are documented here. The morphology of all ammonite jaws suggest a desmoceratoid afnity. The other jaws are identifed as coleoid jaws. They share the overall U-shape and proportions of the outer and inner lamellae with Jurassic lower jaws of Trachyteuthis (Teudopseina). We also document the frst belemnoid arm hooks from the Tethyan Maastrichtian. The fossils described here document the presence of a typical Mesozoic cephalopod assemblage until the end of the Cretaceous in the eastern Tethys.

    IJREISS Volume 2, Issue 8 (August 2012) ISSN: 2250-0588 FOSSIL MAMMALS (RHINOCEROTIDS, GIRAFFIDS, BOVIDS) FROM THE MIOCENE ROCKS OF DHOK BUN AMEER KHATOON, DISTRICT CHAKWAL, PUNJAB, PAKISTAN 1Khizar Samiullah* 1Muhammad Akhtar, 2Muhammad A. Khan and 3Abdul Ghaffar 1Zoology department, Quaid-e-Azam campus, Punjab University, Lahore, Punjab, Pakistan 2Zoology Department, GC University, Faisalabad, Punjab, Pakistan 3Department of Meteorology, COMSATS Institute of Information Technology (CIIT), Islamabad ABSTRACT Fossil site Dhok Bun Ameer Khatoon (32o 47' 26.4" N, 72° 55' 35.7" E) yielded a significant amount of mammalian assemblage including two families of even-toed fossil mammal (Giraffidae, and Bovidae) and one family of odd-toed (Rhinocerotidae) of the Late Miocene (Samiullah, 2011). This newly discovered site has well exposed Chinji and Nagri formation and has dated approximately 14.2-9.5 Ma. This age agrees with the divergence of different mammalian genera. Sedimentological evidence of the site supports that this is deposited in locustrine or fluvial environment, as Chinji formation is composed primarily of mud-stone while the Nagri formation is sand dominated. Palaeoenvironmental data indicates that Miocene climate of Pakistan was probably be monsoonal as there is now a days. Mostly the genera recovered from this site resemble with the overlying younger Dhok Pathan formation of the Siwaliks while the size variation in dentition is taxonomically important for vertebrate evolutionary point of view and this is the main reason to conduct this study at this specific site to add additional information in the field of Palaeontology. A detailed study of fossils mammals found in Miocene rocks exposed at Dhok Bun Ameer Khatoon was carried out.
