    Early Miocene
    Opis:
    The Early Miocene Merkur−North locality (MN 3a) represents the oldest known Miocene ophidian locality in Europe east of Germany. The snake assemblage is characterised by high species diversity and includes the following families: Boidae (Bavarioboa sp.), Colubridae (Coluber dolnicensis, Coluber suevicus, Coluber caspioides, cf. Elaphe sp., Natrix merkurensis sp. nov., Natrix sansaniensis), Elapidae (Elapidae gen. et sp. indet.), and Viperidae (Vipera sp.—“Vipera aspis” complex). Fossils of the extinct species, Coluber dolnicensis, Coluber suevicus, and Natrix sansaniensis, represent their earliest known occurrences. The cranial elements of C. suevicus and N. sansaniensis are described for the first time. Discoveries of cf. Elaphe sp. may represent the earliest fossil member of the genus Elaphe. Elapidae gen. et sp. indet. probably represents the oldest known member of the cobras.

    Opis:
    New suid and sanithere material from Wadi Moghra, early Miocene, Egypt, is described and discussed. The new material greatly improves the sample size and diversity of suoids known from North Africa, and includes one species of Sanitheriidae and three species of Kubanochoerinae. The Moghra suoid assemblage most closely resembles that from Gebel Zelten, Libya, suggesting that at least part of the Moghra deposits may overlap in time with part of Zelten, i.e., is equivalent in age to MN 4–5 of the European mammal zonation, or PIII of the East African one. Information from suids and sanitheres is consistent with previous interpretations, that the Moghra deposits were formed under swampy and littoral paleoenvironmental conditions.

    Opis:
    The brown frogs (Rana temporaria-group) are a monophyletic group in the family Ranidae, which have a scarce fossil record in Europe that begins only in the Late Pliocene. A new fossil from the Dietrichsberg locality (Germany, Thuringia) extends their stratigraphic range back to the Early Miocene, and suggests that their origin lies outside the Western Palaearctic, most probably in Asia, with subsequent immigration in the Burdigalian.

    Opis:
    A new genus and species, Banderomys leanzai, from the Cerro Bandera Formation (early Miocene?) of Neuquén province, Argentina, is described. It is known through a mandibular fragment with two molars and several isolated cheek teeth. With wear the upper molars develop a bilobate pattern, whereas the lowers molars attain a trilophodont one. Banderomysis referred to the Cephalomyidae because it has an “asymmetric” dental pattern as other members of the family, but it is less hypsodont, and therefore it is more primitive than any other contemporary or older cephalomyids so far known. A phylogenetic analysis suggests that the relationships between the Cephalomyidae and the Cavioidea are closer than what was traditionally assumed. The cephalomyids would have radiated in pre−Deseadan times, from an ancestor with a dentition very close to that of Banderomys, and reached their main diversity during the Deseadan–Colhuehuapian lapse, when they constituted the dominant hypsodont rodent group in South America.

    Opis:
    Limestone erratics in the Early Miocene glacio−marine Cape Melville Formation of King George Island, West Antarctica, have yielded Early and Middle Cambrian small skeletal fossils (SSF) accompanied by calcified cyanobacteria, archaeocyath and spiculate sponges, trilobites and echinoderms. The SSF assemblage comprises disarticulated sclerites of chancelloriids, halkieriids, tommotiids, lapworthellids, palaeoscolecids, hyolithelminths, lingulate brachiopods, helcionelloid molluscs, hyoliths, and bradoriids. All 24 described species are common to Antarctica and Australia. Most are recorded here from Antarctica for the first time, including Shetlandia multiplicata gen. et sp. nov. and two new species Byronia? bifida and Hadimopanella staurata. The lithological and fossil contents of the boulders are almost identical with autochthonous assemblages from the Shackleton Limestone in the Argentina Range and Transantarctic Mountains. Cambrian outcrops around the Weddell Sea are a plausible source of the erratics. The fauna is closely similar to that from the uppermost Botomian Wilkawillina Limestone in the Flinders Ranges and Parara Limestone on Yorke Peninsula, and Toyonian Wirrealpa and Aroona Creek Limestones in the Flinders Ranges, as well as the Ramsay Limestone on Yorke Peninsula, all in the Arrowie and Stansbury Basins of South Australia. These very similar faunal and facies successions for Antarctica and Australia strongly support their common biotic and sedimentary evolution on the same margin of a greater Gondwana supercontinent throughout the Early Cambrian.
