Alfred Lord Tennyson described Nature as "red in tooth and claw." Perhaps no other creatures embody that description so well as the deinonychosaurs, those carnivorous dinosaurs infamous for their deadly dentition and distinctive sickle-shaped claw. In the current issue of Nature researchers report having unearthed the first clear evidence of this group in the Southern Hemisphere. Previous discoveries had taken place in North America and Asia. The new species, dubbed Neuquenraptor argentinus, hails from the Cretaceous of Argentina and exhibits the same small, light build and razor-sharp claw that typify the deinonychosaurs. Based on this find, the researchers believe that the group may have originated back when the continents were still lumped together into the single land mass, Pangea.
