Intiornis (meaning "Inti bird", the binominal naming means "Unexpected Sun bird"[1]) is an extinct genus of avisaurid enantiornithean birds which existed in what is now North-West Argentina during the late Cretaceous period (Campanian age).[2]
Description
The genus is known from a partial hind limb found in beds of the Upper Cretaceous Las Curtiembres Formation. Three primary toes on a limb of Intiornis are nearly the same length.[1] It was named by Fernando Emilio Novas, Federico Lisandro Agnolín and Carlos Agustín Scanferla in 2010, and the type species is Intiornis inexpectatus. With the body length of around Шаблон:Cvt[1] Intiornis was the size of a sparrow, thus representing the smallest enantiornithes known from South America. Its closest relative was Soroavisaurus from the Lecho Formation (Maastrichtian age) of northwestern Argentina.[2]

Paleobiology
Long toes of equal length and large curved claws suggest adaptability for perching.[1]
