Willinakaqe is a

hadrosaurid dinosaur described based on fossils from the late Cretaceous (late Campanian-early Maastrichtian stage) of the Río Negro Province of southern Argentina
.

Discovery and naming

Willinakaqe was first named by Rubén D. Juárez Valieri, José A. Haro, Lucas E. Fiorelli and Jorge O. Calvo in 2010 and the type species is Willinakaqe salitralensis. The generic name means "Southern duck-mimic", in the Mapuche language (willi, "south", iná, "mimic" and kaqe, "duck"). The specific name refers to the Salitral.[1]

Willinakaqe is known from several disarticulated specimens, among them juvenile and adult individuals found at the Salitral Moreno site of the Lower Member of the

lambeosaurine.[2][1]

A revision of the original diagnosis of Willinakaqe salitralensis and of fossil material attributed to this species was published by Cruzado Caballero and

nomen vanum.[3]

Phylogeny

The describers assigned Willinakaqe to the

Saurolophidae within the Hadrosauroidea.[1]

In 2010

cladistic analyses by Prieto-Márquez confirmed that the only two hadrosaurid taxa known from South America, Willinakaqe and Secernosaurus, form a clade within the Saurolophinae.[4] Prieto-Márquez & Salinas 2010, Prieto-Márquez, 2010 and Juárez Valieri e.a. considered "Kritosaurus" australis to be identical to Secernosaurus.[1][4]
