Just out @ Paleoceanography and Paleoclimatology Vital effects and ecologic adaptation of photosymbiont-bearing planktonic foraminifera during the Paleocene-Eocene Thermal Maximum, implications for paleoclimate Author(s) Weimin Si, Marie-Pierre Aubry Abstract: Stable isotope-size data of four major planktonic foraminifera lineages from the Paleocene-Eocene Thermal Maximum (PETM, ca. 56 Ma) at two locations (North Atlantic New Jersey shelf and Southern Ocean) are analyzed. By comparing changes in δ13C/ δ18O-size correlation prior to and

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 @ 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
