Issn: 2250-0588 Fossil Mammals
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. -
Eastern Georgia and Western Azerbaijan, South Caucasus)
Synopsis of the terrestrial vertebrate faunas from the Middle Kura Basin (Eastern Georgia and Western Azerbaijan, South Caucasus) MAIA BUKHSIANIDZE and KAKHABER KOIAVA Bukhsianidze, M. and Koiava, K. 2018. Synopsis of the terrestrial vertebrate faunas from the Middle Kura Basin (Eastern Georgia and Western Azerbaijan, South Caucasus). Acta Palaeontologica Polonica 63 (3): 441–461. This paper summarizes knowledge on the Neogene–Quaternary terrestrial fossil record from the Middle Kura Basin accumulated over a century and aims to its integration into the current research. This fossil evidence is essential in understanding the evolution of the Eurasian biome, since this territory is located at the border of Eastern Mediterranean and Central Asian regions. The general biostratigraphic framework suggests existence of two major intervals of the terrestrial fossil record in the area, spanning ca. 10–7 Ma and ca. 3–1 Ma, and points to an important hiatus between the late Miocene and late Pliocene. General aspects of the paleogeographic history and fossil record suggest that the biogeographic role of the Middle Kura Basin has been changing over geological time from a refugium (Khersonian) to a full-fledged part of the Greco-Iranian province (Meotian–Pontian). The dynamic environmental changes during the Quaternary do not depict this territory as a refugium in its general sense. The greatest value of this fossil record is the potential to understand a detailed history of terrestrial life during demise of late Miocene Hominoidea in Eurasia and early Homo dispersal out of Africa. Late Miocene record of the Middle Kura Basin captures the latest stage of the Eastern Paratethys regression, and among other fossils counts the latest and the easternmost occurence of dryopithecine, Udabnopithecus garedziensis, while the almost uninterrupted fossil record of the late Pliocene–Early Pleistocene covers the time interval of the early human occupation of Caucasus and Eurasia. -

La massa corporea di un individuo, oltre alla sua morfologia e struttura, è una delle caratteristiche che influisce maggiormente sulla sua ecologia. La variazione della taglia (body size), sia che essa diminuisca o sia che essa aumenti, porta a cambiamenti importanti nell’ecologia della specie: influisce sulla sua “longevità stratigrafica” (per le specie fossili), sulla complessità delle strutture ornamentali, sulla capacità di occupare determinati habitat, sulla grandezza degli areali che possono occupare (range size), sull’abbondanza (densità di individui) che esse possono avere in un determinato areale, sulla capacità di sfruttare le risorse, sul ricambio generazionale, sulla loro capacità di dispersione e conseguentemente sulla capacità di sopravvivere ai mutamenti ambientali (in seguito ai mutamenti si estinguono o tendono a spostarsi per seguire condizioni ecologiche ottimali – habitat tracking). -

Box 64, FI-00014 Helsinki, Finland *Correspondence: [email protected] October 23, 2017 (preprint) Image credit: Ika Österblad 1 In the fossil record, taxa exhibit a regular pattern of waxing and waning of occupancy, range or diversity between their origin and extinction. This hat-like pattern is well established for species, genera and higher taxa of terrestrial mammals1,2,3, marine invertebrates4,5,6, marine micro-organisms7, and recently living Hawaiian clades of animals and plants8. This pattern appears to contradict the Law of Constant Extinction9, which states that the probability of a taxon’s extinction is independent of its age. Here we show that the apparent contradiction between stochastically constant extinction and the seemingly deterministic “hat” pattern disappears when we consider the peak of taxon’s expansion rather than its final extinction. To a first approximation we find that biotic drivers of evolution pertain mainly to the peak, abiotic drivers mainly to the extinction of taxa. The Red Queen’s Hypothesis9, one of the most influential ideas in evolutionary biology since Darwin, was originally proposed as an explanation of the Law of Constant Extinction. Much effort has since been devoted to the question how this hypothesis, emphasizing biotic interactions, relates to the effects of environmental change. -

Zanda Basin is a late Miocene through Pleistocene pull-apart sag basin (Fig. S1) located just north of the high Himalayan ridgecrest in the west- central part of the orogen (~32° N, 82° E; elevation 3,700-4,500 m). It lies between the South Tibetan Detachment System (STDS) to the southwest, and the Indus Suture to the northeast and the Gurla Mandhata and Qusum (Leo Pargil) metamorphic core complexes to the southeast and northwest, respectively. The STDS is an early-mid Miocene (25) series of north-dipping, low- angle, top-to-the-north normal faults which place low-grade Paleozoic-Mesozoic metasedimentary rocks on high-grade gneisses and granites of the Greater Himalayan sequence. In the Zanda Basin region the Oligo-Miocene Great Counter Thrust, a south-dipping, top-to-the- north thrust system, modifies the Indus Suture. The age of exhumation of the Gurla Mandhata and Qusum (Leo Pargil) metamorphic core complexes has been defined by 40Ar/39Ar analysis of micas to be ~9 Ma (26) or 14-16 Ma (27), respectively. -
