Just out @ Nature Ecology & Evolution Complex neuroanatomy in the rostrum of the Isle of Wight theropod Neovenator salerii Author(s) Chris Tijani Barker, Darren Naish, Elis Newham, Orestis L. Katsamenis & Gareth Dyke Abstract: The discovery of large, complex, internal canals within the rostra of fossil reptiles has been linked with an enhanced tactile function utilised in an aquatic context, so far in pliosaurids, the Cretaceous theropod Spinosaurus, and the related spinosaurid Baryonyx. Here, we report the presence
On the News @ ABC Title: Dinosaur discovery in Winton could hold key to sauropods diet Nicole Bond Excerpt: “Scientists are hopeful the discovery of a fossilised dinosaur skeleton in outback Queensland will shed light on what was on the menu around 95 million years ago. The most complete sauropod skeleton ever found in the southern hemisphere is being dug up at a sheep station near Winton, in western Queensland.
On the News @ The Sydney Morning Herald Title: Rare bones bring stampede of dinosaur experts to tiny Qld town Ruth McCosker Excerpt: “Scientists from around Australia have flown to a small western Queensland town hoping they will be able to piece together the country’s largest find of fossilised rare dinosaur remains.
