Novas and Poh report on the discovery of a new, Late Cretaceous maniraptoran, Neuquenraptor argentinus gen. et sp. nov. The presence of this deinonychosaurian theropod in the Southern Hemisphere shows that the Cretaceous theropod faunas from the southern continents (South America and Africa) shared greater similarity with those of the northern landmasses than previously thought, and suggests that deinonychosaurians were probably distributed worldwide at least by the beginning of the Cretaceous period.
