Classification: Chordata,‭ ‬Reptilia,‭ ‬Dinosauria,‭ ‬Saurischia,‭ ‬Theropoda,‭ ‬Coelurosauria,‭ ‬Maniraptoriformes,‭ ‬Alvarezsauroidea,‭ ‬Alvarezsauridae,‭ ‬Patagonykinae.
Species: P.‭ ‬puertai‭ (‬type‭)‬.
Diet: Insectivore.
Size: Roughly estimated around ‬2‭ ‬meters long, but estimates vary widely.

Time period: Turonian to Coniacian of the Cretaceous.
Fossil representation: Partial post cranial remains.

       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.
