For the International Council of Museums (ICOM, 2001) A museum is "a permanent, non-profit institution at the service of society and its development, open to the public and which acquires, preserves, investigates, disseminates and exposes material witness of man and his environment, for education and enjoyment of society. " Plácido Cidade Nuvens Paleontology Museum linked to the Regional University of Cariri URCA was created to safeguard the fossiliferous heritage of the Araripe Basin.
The idealization of the creation of this museum by its founder was to "stop the unleashed sangria that is the trafficking of fossils in the Region of the Araripe Basin". It is not redundant to say that the most depleted fossiliferous region in the world was the Araripe Basin. National and international institutions, as well as private collectors, have for decades had fossils from the Araripe Basin as their target. Nowadays, awareness campaigns of the local populations are carried out by Araripe Geopark.
