Museu de Paleontologia da Universidade Regional do Cariri, Paleontology museum in Santana do Cariri, Brazil.

The Museu de Paleontologia Plácido Cidade Nuvens, run by the Regional University of Cariri, holds over eleven thousand pieces, mainly fossils from the Santana Group of the Araripe Basin. Its collection includes pterosaurs, the dinosaurs Irritator challengeri and Angaturama limai, fish, plants and petrified trunks. The museum was renamed in 2018 after its founder, Plácido Cidade Nuvens.

The museum was established in 1985 by Professor Plácido Cidade Nuvens while he served as mayor, then transferred to the Regional University in 1991. The collection preserves life forms from a period when this region was covered by a tropical sea millions of years ago.

The institution functions as a research center for paleontological studies, conducting systematic fossil excavations throughout the Araripe Basin region of Brazil.

The museum sits in Santana do Cariri, in the Cariri region of Ceará, and receives about 10,000 visitors a year. It is open every day except Monday. Through its Technological Diffusion Center it runs lectures, courses and training sessions, so groups should arrange visits in advance.

The fossils date to approximately 110 million years ago when warm seas dominated this region and supported diverse marine life. This geological period is so thoroughly preserved in the Santana Formation that researchers worldwide use it for comparative studies.
