Ibirania

Ibirania (meaning "Ibirá wanderer" or "tree wanderer") is a genus of dwarf saltasaurine titanosaur dinosaur from the Late Cretaceous (Santonian to Campanian) São José do Rio Preto Formation (Bauru Basin) of Southeast Brazil. The type species is Ibirania parva. It is one of the smallest sauropods known to date, comparable in size to the titanosaur Magyarosaurus.

== Discovery and naming == The Ibirania holotype specimen, LPP-PV-0200–0207, was discovered in layers of the São José do Rio Preto Formation on the Garcia Brothers Farm in Vila Ventura, Ibirá Municipality, northeastern São Paulo State, Brazil, which dates to the late Santonian to early Campanian ages of the late Cretaceous period. The holotype consists of a dorsal vertebra, partial caudal vertebrae, a fragmentary radius and ulna, a partial metacarpal, and a nearly complete metatarsal. Additional material, including partial cervical, dorsal, and caudal vertebrae, fragments of a fibula, and a nearly complete fibula, was also referred to Ibirania.
