Just out @ PalZ First record of insects in lignite-bearing formations (upper Eocene) of the central German Leipzig Embayment Author(s) Lutz Kunzmann, Christian Müller, Karolin Moraweck, Dorothea Bräutigam, Torsten Wappler, André Nel Abstract: The first unequivocal insect remains from compression plant assemblages of the central German Leipzig Embayment (former Weißelster Basin) are reported and briefly described. The fossil taphocoenosis comes from the upper Bartonian or lower Priabonian Luckenau Clay complex (lignite-bearing Borna Formation) that represents sediments of

Just out @ PalZ Goniatites sphaericus (Sowerby, 1814), the archetype of Palaeozoic ammonoids: a case of decreasing phenotypic variation through ontogeny Author(s) Dieter Korn Abstract: The Late Viséan (Early Carboniferous) ammonoid species Goniatites sphaericus (Sowerby, 1814) is revised with the use of the type material. With respect to conch morphology, suture line and particularly shell ornament, it is regarded as a senior synonym of the species Goniatites fimbriatus (Foord and Crick, 1897) and must therefore be re-established as

Just out @ Palaeontology Brachiopods: origin and early history Author(s) David A. T. Harper, Leonid E. Popov, Lars E. Holmer Abstract: Despite many major advances in recent years, three key challenges remain in bringing clarity to the early history of the phylum: (1) identifying the origin, morphology and life modes of the first brachiopods; (2) understanding the relationships of the major groups to each other and higher sister taxa; and (3)

Just out @ PalZ Astragali of Pakicetidae and other early-to-middle Eocene archaeocetes (Mammalia, Cetacea) of Pakistan: locomotion and habitat in the initial stages of whale evolution Author(s) Philip D. Gingerich, Kurt Heissig, Ryan M. Bebej, Wighart von Koenigswald Abstract: Richard Dehm and colleagues of the Bayerische Staatssammlung für Paläontologie und Geologie in Munich made an important collection of early-to-middle Eocene mammals at Ganda Kas in Pakistan during the winter of 1955/56. The genera and species Ichthyolestes pinfoldi and Gandakasia potens were named

Just out | A fossil unicorn crestfish (Teleostei, Lampridiformes, Lophotidae) from the Eocene of Iran @ PeerJ

Just out @ PeerJ A fossil unicorn crestfish (Teleostei, Lampridiformes, Lophotidae) from the Eocene of Iran Author(s) Donald Davesne Abstract: Lophotidae, or crestfishes, is a family of rare deep-sea teleosts characterised by an enlarged horn-like crest on the forehead. They are poorly represented in the fossil record, by only three described taxa. One specimen attributed to Lophotidae has been described from the pelagic fauna of the middle-late Eocene Zagros Basin, Iran. Originally

Just out @ PeerJ The comparative osteology of Plesiochelys bigleri n. sp., a new coastal marine turtle from the Late Jurassic of Porrentruy (Switzerland) Author(s) Christian Püntener, Jérémy Anquetin, Jean-Paul Billon-Bruyat Abstract: Background During the Late Jurassic, several groups of eucryptodiran turtles inhabited the shallow epicontinental seas of Western Europe. Plesiochelyidae are an important part of this first radiation of crown-group turtles into coastal marine ecosystems. Fossils of Plesiochelyidae occur in many European localities, and are especially abundant

Signs of decompression illness are still found among turtles but whales and seals are unaffected. In humans, the risk of decompression illness is five times increased in individuals with

Irvine, Justin V. Strauss Abstract: Vase-shaped microfossils (VSMs), interpreted as the remains of testate amoebae, are found in late Tonian sedimentary rocks around the world. Here we explore the taxonomy, taphonomy and stratigraphical occurrence of VSMs from the Callison Lake Formation of the Coal Creek
