Bernor Abstract: Herein, the authors report on skulls, mandibles and postcranial specimens of two species of Chinese Sivalhippus, S. ptychodus and S. platyodus. We frame our description and analyses within the context of newly described characters of the cheek teeth of Hippotherium from the Pannonian

Just out @ Journal of Mammalian Evolution Morphology of the Middle Ear Ossicles in the Rodent Perimys (Neoepiblemidae) and a Comprehensive Anatomical and Morphometric Study of the Phylogenetic Transformations of these Structures in Caviomorphs Author(s) Leonardo Kerber, Marcelo R. Sánchez-Villagra Abstract: The extinct clade of caviomorph rodents Neoepiblemidae includes forms that lived in South America from the early Miocene to Pliocene. Among them is Perimys. The exceptional preservation of ear ossicles in this rodent is described and analyzed in

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 @ Palaeogeography, Palaeoclimatology, Palaeoecology Quantitative palaeobiogeographical analysis of South American Neogene Chioninae (Bivalvia: Veneridae) Author(s) Damián Eduardo Pérez, Martín Daniel Ezcurra Abstract: Chionine bivalves are one of the most important components of Neogene and Recent molluscan faunas in southern South America, but it was not until recently that their phylogenetic relationships has been explored quantitatively. Based on this robust framework, we analyzed the palaeobiogeographical history of the group. The geographic

Just out @ The Holocene Near-surface permafrost aggradation in Northern Hemisphere peatlands shows regional and global trends during the past 6000 years Author(s) Claire C Treat, Miriam C Jones Abstract: The history of permafrost aggradation and thaw in northern peatlands can serve as an indicator of regional climatic history in regions where records are sparse. We infer regional trends in the timing of permafrost aggradation and thaw in North American and

Just out @ Paleobiology Punctuated changes in the morphology of an endemic diatom from Lake Titicaca Author(s) Trisha L. Spanbauer, Sherilyn C. Fritz, Paul A. Baker Abstract: High levels of biodiversity and endemism in ancient lakes have motivated research on evolutionary processes in these systems. Drill-core records from Lake Titicaca (Bolivia, Peru), an ancient lake in the high-elevation Altiplano, record the history of climate, landscape dynamics, and diatom evolution. That record

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
