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

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 @ 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

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

Just out @ Journal of Mammalian Evolution Growth Pattern and Functional Morphology of the Cervical Vertebrae in the Gerenuk (Litocranius walleri): The Evolution of Neck Elongation in Antilopini (Bovidae, Artiodactyla) Author(s) Megu Gunji, Hideki Endo Abstract: Long necks have evolved independently in several different taxa, but the processes underlying the evolution of this trait are not yet fully understood. In this study, we examined the skeletal mechanism underlying the neck elongation

Just out @ Current Biology Evolution: Uprooting the Dinosaur Family Tree Author(s) Stephen L. Brusatte Summary: A provocative new study rearranges the base of the dinosaur evolutionary tree, upending 130 years of consensus. Does it hold up to scrutiny? Excerpt:  Phylogenetics rarely make the headlines. Last month, however, the Atlantic reported on a bombshell discovery that in their words would “shake dinosaur paleontology to its core”. That same day, the Guardian went with

Just out @ Evolution Interactions within and between clades shaped the diversification of terrestrial carnivores Author(s) Mathias M. Pires, Daniele Silvestro, Tiago B. Quental Abstract: A longstanding debate in evolutionary biology and paleontology is whether ecological interactions such as competition impose diversity dependence on speciation and extinction rates. Here we analyze the fossil record of terrestrial mammalian carnivores in North America and Eurasia using a Bayesian framework to assess whether their

One of the “terrible lizards” is Gigantoraptor erlianensis, a dinosaur that lived during the late Cretaceous Period that was discovered in Erenhot, North China’s Inner Mongolia Autonomous Region. The
