Description
Source: Wikipédia
The Açu Formation is an Early Cretaceous (Albian) geologic formation of the Potiguar Basin in Ceará, northeastern Brazil. The formation comprises coarse-grained sandstones deposited in a fluvio-deltaic environment. The Açu Formation, belonging to the Apodi Group, has provided fossils of an indeterminate rebbachisaurid.

- Fazenda Pingos tracksite : Rio Grande do Norte - ? 79477 "One can arrive there by leaving the town of Assú and following along the BR 304 highway toward the Mossoró city (north-westward) for 16 km – 1 km NW from the CONPASA (Construtora Paraibana S.A.) and then entering a dirt road on the left untill Fazenda Pingos (5°34’10” S, 37°02’20” W, datum WGS 84). In that site, there is an interesting cavern, called Gruta dos Pingos, which can be used as a geomorphological reference mark (Figure 2b). In fact, the main tracks are located on the surface about 15 m over its “ceiling” of it."
