Just out @ Historical Biology What happens to dead birds left in a cave and its vicinity for a quarter of a century? A taphonomic experiment Author(s) Zbigniew M. Bochenski, Krzysztof Wertz & Teresa Tomek Abstract: This paper describes a bird carcass-monitoring experiment carried out in a limestone cave and its immediate vicinity in southern Poland for almost a quarter of a century. Some specimens deposited outside the cave were preserved

Just out @ Royal Society Open Science Palaeoecological implications of the preservation potential of soft-bodied organisms in sediment-density flows: testing turbulent waters Author(s) Orla G. Bath Enright, Nicholas J. Minter, Esther J. Sumner Abstract: Interpreting how far organisms within fossil assemblages may have been transported and if they all originated from the same location is fundamental to understanding whether they represent true palaeocommunities. In a three-factorial experimental design, we used an

Just out @ Proceedings of the Geologists’ Association Neoichnology of Chalk cobbles from north Norfolk, England: implications for taphonomy and palaeoecology Author(s) Stephen K. Donovan Abstract: The study of marine biota of the North Sea from the perspective of its relevance to palaeontology (Aktuopaläontologie) has enabled modern patterns and processes to be identified that can also be recognised in ancient communities. A collection of Chalk cobbles from the coast of north

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 @ Journal of Paleontology Exceptionally preserved conodont apparatuses with giant elements from the Middle Ordovician Winneshiek Konservat-Lagerstätte, Iowa, USA Author(s) Huaibao P. Liu, Stig M. Bergström, Brian J. Witzke, Derek E. G. Briggs, Robert M. McKay, Annalisa Ferretti Abstract: Considerable numbers of exceptionally preserved conodont apparatuses with hyaline elements are present in the middle-upper Darriwilian (Middle Ordovician, Whiterockian) Winneshiek Konservat-Lagerstätte in northeastern Iowa. These fossils, which are associated with

Just out @ Lethaia An integrative ichnological and taphonomic approach in a transgressive–regressive cycle: a case study from Devonian of Paraná Basin, Brazil Author(s) Daniel Sedorko, Elvio P. Bosetti, Renata G. Netto Abstract: The palaeoenvironmental context of a section of the Devonian Ponta Grossa Formation (Paraná Basin) was examined using an integrated ichnological and taphonomic approach. Three taphofacies (T-A, T-B and T-C) and six ichnofabrics are recognized. T-A is mainly

On the News @ The Washington Post Title:  ‘Rare as winning the lottery’: New dinosaur fossil so well-preserved it looks like a statue Excerpt: “Before being assembled into something recognizable at a museum, most dinosaur fossils look to the casual observer like nothing more than common rocks. No one, however, would confuse the over 110 million-year-old nodosaur fossil for a stone. The fossil, being unveiled today in Canada’s Royal Tyrrell Museum

Abbott, Sumit Kumar, Shane S. O’Reilly, Paul Donohoe, Suryendu Dutta, Roger E. Summons and Jakob Vinther Abstract: Recent studies have suggested the presence of keratin in fossils dating back to the Mesozoic. However, ultrastructural studies revealing exposed melanosomes in many fossil keratinous tissues suggest that keratin

Just out @ Historical Biology Carnivore taphonomy in South America: a review of actualistic studies and their implications in the southern Neotropics Author(s) Mariana Mondini Abstract: Actualistic studies on mammalian carnivore taphonomy in southern South America are reviewed here, including pumas, small cats, foxes, and other, smaller carnivores. Patterns for different carnivore taxa and their variation are elicited. Also temporal and spatial variability is analysed, and comparisons are made to other carnivores
