On the News @ The Guardian Title:  Mattresses, the Universe and Everything: fossils of Ediacaran biota Excerpt: “In Life, the Universe and Everything, Douglas Adams has left Marvin the Paranoid Android stranded and walking in circles (literally) on Sqornshellous Zeta. This is a swampy planet, where the dominant life form is the mattress. Marvin chats with Zem, a perky and affable pocket-sprung mattress, who encourages him to be ‘more mattressy*’.

Just out @ Geobiology A geochemical study of the Ediacaran discoidal fossil Aspidella preserved in limestones: Implications for its taphonomy and paleoecology Author(s) N. Bykova, B. C. Gill, D. Grazhdankin, V. Rogov, S. Xiao Abstract: The Ediacara biota features the rise of macroscopic complex life immediately before the Cambrian explosion. One of the most abundant and widely distributed elements of the Ediacara biota is the discoidal fossil Aspidella, which is

Just out @ PalZ Trilobites of the Galgenberg Member (Tannenknock Formation), middle Cambrian Stage 5, Franconian Forest, Germany: a paradigmatic lowermost middle Cambrian West Gondwanan fauna Author(s) Gerd Geyer Abstract: Earliest middle Cambrian rocks in the Franconian Forest, formerly known as the ‘Galgenberg Formation’, include a moderately diverse fauna with a characteristic West Gondwanan, Atlas-type trilobite assemblage with often surprisingly well-preserved specimens. The hitherto inadequately characterised and poorly described assemblage includes

Just out @ PalZ An unusual ferruginous-calcitic Frutexites microbialite community from the lower Cambrian of the Flinders Ranges, South Australia Author(s) Joachim Reitner, Nick Langsford, Peter D. Kruse Excerpt: “The Flinders Ranges of South Australia are famous for their fossiliferous early Cambrian faunas, especially their archaeocyaths, trilobites, early molluscs and sponges, among other fossil groups (e.g., Gravestock 1984; Bengtson et al. 1990; James and Gravestock 1990; Kruse 1991; Reitner 1992;

Just out @ Palaeogeography, Palaeoclimatology, Palaeoecology Possible evidence of primary succession in a juvenile-dominated Ediacara fossil surface from the Flinders Ranges, South Australia Author(s) Lily M. Reid, Diego C. García-Bellido, Justin L. Payne, Bruce Runnegar, James G. Gehling Abstract: Ediacara fossil surfaces from the Flinders Ranges (South Australia) commonly record excellent preservation quality and can provide a palaeoecological window into some of the oldest communities on Earth (ca. 555 Ma). An excavated

Gabriela Mángano, Luis A. Buatois Abstract: The nature of the Cambrian Explosion, one of the most critical events in Earth history, has been a major topic of discussion. The trend of increasing morphological complexity and taxonomic diversity of trace fossils within this interval

Just out @ Palaentology How well does a part represent the whole? A comparison of cranidial shape evolution with exoskeletal character evolution in the trilobite family Pterocephaliidae Author(s) Melanie J. Hopkins Abstract: For taphonomic and practical reasons, our understanding of morphological evolution within and among species is based primarily on measurements taken from one or a few morphological traits. However, patterns can be highly dependent on trait choice, making it

Just out @ Journal of Paleontology Title:  Middle Cambrian trilobites from the Ekspedition Bræ Formation of North Greenland, with a reappraisal of the genus Elrathina Author(s) Gerd Geyer, John S. Peel Abstract: The richly fossiliferous Ekspedition Bræ Formation of North Greenland yields a typical oligospecific fossil assemblage with well-preserved trilobites, helcionelloids, and lingulate brachiopods. The trilobites include Itagnostus subhastatus new species, Itagnostus sp. cf. I. gaspensis (Rasetti, 1948), Elrathina aphrodite
