Just out @ Marine Micropaleontology Variability in diatom and silicoflagellate assemblages during mid-Pliocene glacial-interglacial cycles determined in Hole U1361A of IODP Expedition 318, Antarctic Wilkes Land Margin Author(s) Linda H. Armbrecht, Vikki Lowe, Carlota Escutia, Masao Iwai, Robert McKay, Leanne K. Armanda Abstract: The Earth is currently experiencing climatic changes that will result in similar environmental conditions to those experienced during the mid-Pliocene (5.3–3.6 million years ago [Ma]), such as similar atmospheric CO2 concentrations, elevated sea surface

Just out @ Proceedings of the Royal Society B Lizards of the lost arcs: mid-Cenozoic diversification, persistence and ecological marginalization in the West Pacific Author(s) Paul M. Oliver, Rafe M. Brown, Fred Kraus, Eric Rittmeyer, Scott L. Travers, Cameron D. Siler Abstract: Regions with complex geological histories often have diverse and highly endemic biotas, yet inferring the ecological and historical processes shaping this relationship remains challenging. Here, in the context of the taxon cycle model

Just out | The evolution of tail weaponization in amniotes @ Proceedings of the Royal Society B

Just out @ Proceedings of the Royal Society B The evolution of tail weaponization in amniotes Author(s) Victoria M. Arbour, Lindsay E. Zanno Abstract: Weaponry, for the purpose of intraspecific combat or predator defence, is one of the most widespread animal adaptations, yet the selective pressures and constraints governing its phenotypic diversity and skeletal regionalization are not well understood. Here, we investigate the evolution of tail weaponry in amniotes, a rare

Just out @ Journal of African Earth Sciences A new approach to biostratigraphy in the Karoo retroarc foreland system: Utilising restricted-range palynomorphs and their first appearance datums for correlation Author(s) Natasha Barbolini, Bruce Rubidge, Marion K. Bamford Abstract: The main Karoo Basin (MKB), internationally renowned for its wealth of fossil tetrapods, has been lithostratigraphically subdivided into three discrete regions: two (east and west) proximal facies adjacent to the Cape Fold Belt, and a distal facies, away

Just out | Paleoecological evidence for decadal increase in phytoplankton biomass off northwestern Australia in response to climate change @ Ecology and Evolution

Just out @ Ecology and Evolution Paleoecological evidence for decadal increase in phytoplankton biomass off northwestern Australia in response to climate change Author(s) Zineng Yuan, Dongyan Liu, John K. Keesing, Meixun Zhao, Shixin Guo, Yajun Peng, Hailong Zhang Abstract: Ocean warming can modify the phytoplankton biomass on decadal scales. Significant increases in sea surface temperature (SST) and rainfall in the northwest of Australia over recent decades are attributed to climate

Just out | The late Pliocene palaeoenvironments and palaeoclimates of the western Iberian Atlantic margin from the Rio Maior flora @ Palaeogeography, Palaeoclimatology, Palaeoecology

Just out @ Palaeogeography, Palaeoclimatology, Palaeoecology The late Pliocene palaeoenvironments and palaeoclimates of the western Iberian Atlantic margin from the Rio Maior flora Author(s) Manuel Vieira, Matthew James Pound, Diamantino I. Pereira Abstract: Using a revised chronology, a new palynological study on the late Pliocene (Piacenzian and earliest Gelasian) Rio Maior site of the Tagus Basin in western Portugal has been undertaken from the F98 core. Combining light microscopy and scanning electron

Just out | High-quality fossil dates support a synchronous, Late Holocene extinction of devils and thylacines in mainland Australia @ Biology Letters

Just out @ Biology Letters High-quality fossil dates support a synchronous, Late Holocene extinction of devils and thylacines in mainland Australia Author(s) Lauren C. White, Frédérik Saltré, Corey J. A. Bradshaw, Jeremy J. Austin Abstract: The last large marsupial carnivores—the Tasmanian devil (Sarcophilis harrisii) and thylacine (Thylacinus cynocephalus)—went extinct on mainland Australia during the mid-Holocene. Based on the youngest fossil dates (approx. 3500 years before present, BP), these extinctions are often considered synchronous

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
