Just out @ Rivista Italiana di Paleontologia e Stratigrafia Composition and Occurence of the Grandispora Maculosa Zonal Assemblage (Mississipian) in the Subsurface of the Carnarvon Basin and the Coolcalalaya Sub-Basin of Western Australia, and its Gondwanan Distribution Author(s) Geoffrey Playford, Arthur J. Mory Abstract: The Grandispora maculosa miospore assemblage – initially described in 1968 from Middle-Late Mississippian strata of New South Wales (eastern Australia) – is well represented in samples examined

Just out @ Biology Letters Inference of facultative mobility in the enigmatic Ediacaran organism Parvancorina Author(s) Simon A. F. Darroch, Imran A. Rahman, Brandt Gibson, Rachel A. Racicot, Marc Laflamme Abstract: Establishing how Ediacaran organisms moved and fed is critical to deciphering their ecological and evolutionary significance, but has long been confounded by their non-analogue body plans. Here, we use computational fluid dynamics to quantitatively analyse water flow around the Ediacaran

Just out | Island extinctions weren't inevitable @ Science

Just out @ Science Island extinctions weren’t inevitable Author(s) April Reese Summary: In the last few thousand years, the arrival of humans in new territory almost always brought overhunting, habitat destruction, or invasive species that killed off native creatures. Nowhere did this seem truer than on islands, with their limited resources and naïve prey. But evidence presented at a meeting at Australian National University (ANU) in Canberra last month suggests that in

Just out @ PLOS one Highly regulated growth and development of the Ediacara macrofossil Dickinsonia costata Author(s) Scott D. Evans, Mary L. Droser, James G. Gehling Abstract: The Ediacara Biota represents the oldest fossil evidence for the appearance of animals but linking these taxa to specific clades has proved challenging. Dickinsonia is an abundant, apparently bilaterally symmetrical Ediacara fossil with uncertain affinities. We identified and measured key morphological features of over

On the News @ EurekAlert! Title:  UCR study sheds light on Earth’s first animals Excerpt: “More than 550 million years ago, the oceans were teeming with flat, soft-bodied creatures that fed on microbes and algae and could grow as big as bathmats. Today, researchers at the University of California, Riverside are studying their fossils to unlock the secrets of early life. In their latest study, published today in the journal PLOS

Just out | The timetable of evolution @ Science Advances

Just out @ Science Advances The timetable of evolution Author(s) Andrew H. Knoll, and Martin A. Nowak Abstract: The integration of fossils, phylogeny, and geochronology has resulted in an increasingly well-resolved timetable of evolution. Life appears to have taken root before the earliest known minimally metamorphosed sedimentary rocks were deposited, but for a billion years or more, evolution played out beneath an essentially anoxic atmosphere. Oxygen concentrations in the atmosphere and

Just out | New azooxanthellate genus of Scleractinia (Flabellidae) from the Australian Cenozoic @ Journal of Paleontology

Just out @ Journal of Paleontology New azooxanthellate genus of Scleractinia (Flabellidae) from the Australian Cenozoic Author(s) Stephen D. Cairns Abstract: A new genus of flabellid scleractinian coral, Periplacotrochus, is described from the late Eocene to middle Miocene of Victoria, South Australia, and Tasmania. It differs from Placotrochus in having a pedicellate base, and from Flabellum in having a lamellar columella. Six previously described species are redescribed, illustrated, and reassigned to

Just out @ Paleobiology Relating Ediacaran Fronds Author(s) T. Alexander Dececchi, Guy M. Narbonne, Carolyn Greentree and Marc Laflamme Abstract: Ediacaran fronds are key components of terminal-Proterozoic ecosystems. They represent one of the most widespread and common body forms ranging across all major Ediacaran fossil localities and time slices postdating the Gaskiers glaciation, but uncertainty over their phylogenetic affinities has led to uncertainty over issues of homology and functional morphology between and

On the News @ Stuff, The Press Title:  Huia-like bird could sing from the branches once again, but what are the limits? Excerpt: “Woolly mammoths stomping the arctic plains. Huia birds flitting between branches in the Wairarapa. Velociraptors roaming the Canterbury plains. OK, maybe not the velociraptors, but such a world is being painted by research into bringing animals back from extinction, an idea once reserved for dinosaur movies and science-fiction books. As

Just out @ Nature Communications Earliest signs of life on land preserved in ca. 3.5 Ga hot spring deposits Author(s) Tara Djokic, Martin J. Van Kranendonk, Kathleen A. Campbell, Malcolm R. Walter & Colin R. Ward Abstract: The ca. 3.48 Ga Dresser Formation, Pilbara Craton, Western Australia, is well known for hosting some of Earth’s earliest convincing evidence of life (stromatolites, fractionated sulfur/carbon isotopes, microfossils) within a dynamic, low-eruptive volcanic caldera
