Just out @ BMC Evolutionary Biology The phylogeny of fossil whip spiders Author(s) Russell J. Garwood, Jason A. Dunlop, Brian J. Knecht and Thomas A. Hegna Abstract: Background Arachnids are a highly successful group of land-dwelling arthropods. They are major contributors to modern terrestrial ecosystems, and have a deep evolutionary history. Whip spiders (Arachnida, Amblypygi), are one of the smaller arachnid orders with ca. 190 living species. Here we restudy

Just out @ Bulletin of Geosciences Revision of Dendraena pinnatilobata Němejc from the Pennsylvanian of the Czech Republic Author(s) Frojdova J, Pšenička J, Bek J, Martinek K Abstract: Dendraena pinnatilobata Němejc is a Pennsylvanian true fern, which is known from the Stradonice locality (Czech Republic) only. All specimens of Dendraena pinnatilobata are preserved as three-dimensionally in volcaniclastic of Whestone Horizon (Radnice Member, Kladno Formation). Revision of this species includes detail

Just out | Beak from the body chamber of an Early Carboniferous shelled longiconic coleoid cephalopod from Arkansas, USA @ Lethaia

Just out @ Lethaia Beak from the body chamber of an Early Carboniferous shelled longiconic coleoid cephalopod from Arkansas, USA Author(s) Larisa A. Doguzhaeva, Royal H. Mapes Abstract: Here we report the discovery of an Early Carboniferous (Late Visean) 3D cephalopod beak displaying significant similarity to the lower beak of Recent coleoids. It was uncovered in a fragmentarily preserved, longiconic shell from the Moorefield Formation in Arkansas, USA. This shell

It's a Bug's World | New Species Reported This Week

It’s a bug’s world and it was definitely a bug’s week. Invertebrates were clearly dominant in new species reported this week, insects and beetles being the most numerous. Arthropodes, echinoderms, mollucs, cycads, conodonts, radiolaria were also described in a week full of new taxonomic descriptions. The new species reported this week come from America (USA and Patagonia), from Africa (Tunisia and Madagascar), Europe (Germany, Austria and Russia), and Asia (Myanmar). Full account of fossil species reported this week: Palaeosiamoglaris leinhardi gen. et sp. nov., P. burmica sp. nov., and P. inexpectata sp. nov., three new Prionoglarididae from Cretaceous Burmese amber,

Just out @ Paleontological Research Tainoceratid and Liroceratid Nautilids from the Upper Mississippian Imo Formation of Arkansas, Midcontinent North America Author(s) Shuji Niko and Royal H. Mapes Abstract: As the third installment of our study to describe the cephalopod fauna of the Upper Mississippian Imo Formation, four species of late Chesterian (= Serpukhovian; late early Carboniferous) nautilids are recorded from the dark gray shale of the formation in northwest Arkansas,

Just out | Two new Carboniferous Asteroidea (Echinodermata) of the family Urasterellidae @ Neues Jahrbuch für Geologie und Paläontologie

Just out @ Neues Jahrbuch für Geologie und Paläontologie Two new Carboniferous Asteroidea (Echinodermata) of the family Urasterellidae Author(s) Blake, Daniel B. Abstract: Two new genera and species of the Paleozoic asteroid (Echinodermata) family Urasterellidae, Anthroosasterias stibareus and Staurasterias elegans, are described from the Carboniferous of the central United States. A revised familial diagnosis is proposed. Compared with earlier Paleozoic urasterellids, the new genera differ in ambulacral and disk morphology,
