Pedra da Galinha Choca (Rock of the Brooding Hen) is a rock formation in the Brazilian city of Quixadá in Ceará, taking its name from its curious shape. It is located 5 km from the city center. Until the early twentieth century was called the Pedra da Arara (Arara's Stone). It consists of inselberg diorites and granites, which are igneous rocks, i.e., formed from cooling magma.
