New enantiornithine bird (Aves, Ornithothoraces) from the
Late Cretaceous of NW Argentina.

A new enantiornithine bird, Intiornis inexpectatus gen.
et sp. nov, is described here. It is based on a partial
hind limb found in beds of the Upper Cretaceous Las
Curtiembres Formation (Campanian), North-West Argentina.
The new taxon is referred to the family Avisauridae on
the basis of its cranially convex third metatarsal.
Several features suggest close relationships between
Intiornis and the avisaurid Soroavisaurus, from the Lecho
Formation (Maastrichtian; North-West Argentina).
Intiornis was the size of a sparrow, thus representing
the smallest Enantiornithes known from South America. The
new species shows adaptations for a perching mode of
life. Moreover, the hypothesis suggesting that the flying
pterosaur reptiles decrease in taxonomic diversity due to
competitive interaction with birds is discussed. The new
