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 15 cm (5.9 in)[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]
