On the News @ AsianScientist Title:  Insect Fossils Shed Light On India’s Geological History Excerpt: “A new species of fungus gnat in Indian amber closely resembles its fossil relatives from Europe, disproving the concept of a strongly isolated Indian subcontinent. These findings have been published in PeerJ. Apart from the new gnat species named Palaeognoriste orientale, the researchers from Germany, India and America also identified two more species of insects encased

Just out @ Palaeobiodiversity and Palaeoenvironments Discontinuities in the microfossil record of middle Eocene Lake Messel: clues for ecological changes in lake’s history? Author(s) Gotthard Richter, Sven Baszio, Michael Wuttke Abstract: We analysed the sediment and small fish coprolites from the 140-m thick lacustrine sediments of the middle Eocene maar lake Messel using material from different outcrops and from the Research Drilling Project 2001 (RDP 2001). The microfauna and microflora of Lake Messel underwent detectable changes

Just out @ Journal of Vertebrate Paleontology First crocodile-tailed lizard (Squamata: Pan-Shinisaurus) from the Paleogene of Europe Author(s) Krister T. Smith Abstract: Crocodile-tailed lizards are represented by a single extant species, Shinisaurus crocodilurus, the Chinese crocodile lizard, which until 2006 was completely unknown in the fossil record. These lizards may play an important role in understanding squamate phylogeny, but their biogeographic history remains murky. A new specimen from the middle Eocene

Reynolds, Peter M. Olde, Austin R. Mast, Emily Lemmon, Alan R. Lemmon, Lindell Bromham Abstract: The frequency of evolutionary biome shifts during diversification has important implications for our ability to explain geographic patterns of plant diversity. Recent studies present several examples of

Just out @ Historical Biology Eolacertidae: a new extinct clade of lizards from the Palaeogene; with comments on the origin of the dominant European reptile group – Lacertidae Author(s) Andrej Čerňanský & Krister T. Smith Abstract: We describe a new lizard taxon, Stefanikia siderea gen. et sp. nov., from the early-middle Eocene locality of Messel in Germany based on a nearly complete skeleton, which we studied using μCT methods. It shares

Just out @ Palaeontologia Electronica The first Eocene rodents from the Pacific Northwest, USA Author(s) Joshua X. Samuels and William W. Korth Abstract: The Oligocene and Miocene faunas of the John Day Basin are diverse and very well-studied, including a large number of small mammal species. Though Eocene floras from Oregon are well-known, Eocene faunas include relatively few taxa from only two described localities in the Clarno area. The first Eocene

Wilson, Clyde L. Calvin and Alexander R. Schmidt Abstract: PREMISE OF THE STUDY: Extant dwarf mistletoes (Arceuthobium M. Bieb., Viscaceae) are hemiparasites with complex roles in nature. They are one of the most severe pests in northern hemisphere conifer forests, but they also
