Just out @ Paleobiology Craniodental functional evolution in sauropodomorph dinosaurs Author(s) David J. Button, Paul M. Barrett and Emily J. Rayfield Abstract: Sauropodomorpha included the largest known terrestrial vertebrates and was the first dinosaur clade to achieve a global distribution. This success is associated with their early adoption of herbivory, and sauropod gigantism has been hypothesized to be a specialization for bulk feeding and obligate high-fiber herbivory. Here, we apply a combination

Just out @ Nature Ecology & Evolution Five palaeobiological laws needed to understand the evolution of the living biota Author(s) Charles R. Marshall Abstract: The foundations of several disciplines can be expressed as simple quantitative laws, for example, Newton’s laws or the laws of thermodynamics. Here I present five laws derived from fossil data that describe the relationships among species extinction and longevity, species richness, origination rates, extinction rates and diversification.

On the News @ The Sun Title:  Discovery of horned ‘triceratops-style’ dinosaur in North America could rewrite Earth’s history Jasper Hamill Excerpt: “Archaeologists have found the remains of a dinosaur that could reshape our understanding of the natural history of planet Earth. The “triceratops-style” beast was discovered after its tooth was dug out of rock in Missippipi. The ceratopsid dinosaur is believed to have roamed across North America between 66 and 68

Just out @ Lethaia Calcareous nannofossil biostratigraphy: historical background and application in Cenozoic chronostratigraphy Author(s) Claudia Agnini, Simonetta Monechi, Isabella Raffi Abstract: Calcareous nannofossils are considered one of the most powerful biostratigraphical tool in marine carbonate sediments especially in open ocean settings. Their origination goes at least as far back as the Triassic (ca. 220 Ma) when they first biomineralized and produced calcite skeletons. Since then, they have evolved rapidly showing

Just out @ PeerJ The first reported ceratopsid dinosaur from eastern North America (Owl Creek Formation, Upper Cretaceous, Mississippi, USA) Author(s) Andrew A. Farke, George E. Phillips Abstract: Ceratopsids (“horned dinosaurs”) are known from western North America and Asia, a distribution reflecting an inferred subaerial link between the two landmasses during the Late Cretaceous. However, this clade was previously unknown from eastern North America, presumably due to limited outcrop of the

Legalov Abstract: Five new species of Entiminae weevils are described from Dominican amber: Diaprepes squamula sp. nov., resembling D. famelicus (Olivier, 1790) from the West Indies; Lachnopus serraticrus sp. nov., resembling L. acuticollis (Gyllenhal, 1834) from Cuba and L. proteus (Olivier, 1807) from Hispaniola in the tribe

Just out @ Palaeontologia Electronica Morphology and sediment deformation of downslope Brasilichnium trackways on a dune slipface in the Nugget Sandstone of northeastern Utah, USA Author(s) George F. Engelmann and Daniel J. Chure Abstract: The presumed synapsid trackway known as Brasilichnium is known by numerous trackways from many localities throughout the eolian deposits of the Late Triassic to Early Jurassic erg that covered much of the western United States. These trackways occur

Just out @ Nature Communications Controlling for the species-area effect supports constrained long-term Mesozoic terrestrial vertebrate diversification Author(s) Roger A. Close, Roger B.J. Benson, Paul Upchurch & Richard J. Butler Abstract: Variation in the geographic spread of fossil localities strongly biases inferences about the evolution of biodiversity, due to the ubiquitous scaling of species richness with area. This obscures answers to key questions, such as how tetrapods attained their tremendous extant
