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 @ 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

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.

Martinelli, Estevan Eltink, Átila A. S. Da-Rosa, Max C. Langer Abstract: The fossil record of non-mammaliaform probainognathian cynodonts is outstanding in the Late Triassic rocks of Brazil and Argentina. Approximately 15 genera are known, providing unique insights in the study of the major skeletal transformations prior to

The show features a mind-blowing combination of real fossils and robotic dinosaurs stretching more than 60 feet (18 meters) in length. Even better, there’s a farting dinosaur and a peeing dinosaur. In our ongoing fascination with the extinct

Just out @ Journal of Vertebrate Paleontology New Triassic teleosts (Actinopterygii, Teleosteomorpha) from northern Italy and their phylogenetic relationships among the most basal teleosts Author(s) Gloria Arratia Abstract: This study provides new evidence of the diversity of Middle–Late Triassic teleosts with the description of new pholidophorids from Italy. The results of the phylogenetic analysis confirm the sister-group relationship [†Aspidorhynchiformes + †Pachycormiformes] as members of Teleosteomorpha and †Prohalecites as the oldest teleosteomorph.
