In Depth

       Although only known from partial remains,‭ ‬Patagonykus is confirmed to have been an alvarezsaur,‭ ‬small bipedal dinosaurs that are thought to have specialised in hunting insects.‭ ‬Dinosaurs like Patagonykus were once thought to have been restricted to the lower stages of the upper Cretaceous,‭ ‬however the discovery of Bonapartenykus in‭ ‬2012‭ ‬has revealed these forms of alvarezsaur survived in South America until the last stages of the Cretaceous.

       Patagonykus likely shared its ecosystem with dinosaurs such as Megaraptor,‭ ‬Unenlagia,‭ ‬Rinconsaurus and Antarctosaurus which have all been discovered in the Neuquen Formation.
