The Feliz Deserto Formation is a geologic formation of the Early Cretaceous age (Berriasian to Valanginian) in northeastern Brazil's Sergipe-Alagoas Basin. The formation belongs to the rift phase, in which a great lake formed. [1]
The formation provided fossils of bivalve and gastropod molluscs, vertebrate remains of Lepidotes fish and teeth of crocodylomorphs and spinosaurids, the oldest of the family reported in South America. [1] [2]
Alagoas, officially State of Alagoas, is one of the 27 federative units of Brazil and is situated in the eastern part of the Northeast Region. It borders: Pernambuco ; Sergipe (S); Bahia (SW); and the Atlantic Ocean (E). Its capital is the city of Maceió. It has 1.6% of the Brazilian population and produces 0.8% of the Brazilian GDP. It is made up of 102 municipalities and its most populous cities are Maceió, Arapiraca, Palmeira dos Índios, Rio Largo, Penedo, União dos Palmares, São Miguel dos Campos, Santana do Ipanema, Delmiro Gouveia, Coruripe, and Campo Alegre.
Sergipe, officially State of Sergipe, is a state of Brazil. Located in the Northeast Region along the Atlantic coast of the country, Sergipe is the smallest state in Brazil by geographical area at 21,910 square kilometres (8,460 sq mi), larger only than the Federal District. Sergipe borders Bahia to the south and west and Alagoas to the north. Aracaju is the capital and the largest city in the state; the state is divided into 75 municipalities. The state has 1.1% of the Brazilian population and produces only 0.6% of the Brazilian GDP.
The BR-101 is a longitudinal highway of Brazil. It is the longest in the country with a length of nearly 4,800 km (3,000 mi), and it is considered one of the most important highways in the country, along with BR-116.

Feliz Deserto is a municipality located in the south of the Brazilian state of Alagoas. Its population is 4,779 (2020) and its area is 92 km².
Riachuelo is a municipality located in the Brazilian state of Sergipe. Its population was 10,284 (2020) and covers 78.31 km2 (30.24 sq mi). Riachuelo has a population density of 130 inhabitants per square kilometer. Riachuelo is located 23 km (14 mi) from the state capital of Sergipe, Aracaju. Riachuelo borders the municipalities of Laranjeiras, Divina Pastora, Santa Rosa de Lima, and Areia Branca, all within the state of Sergipe. The municipality is site of the Nossa Senhora da Penha Sugar Plantation and the Chapel of the Nossa Senhora da Penha Sugar Plantation. The chapel was listed as a historic structure by National Institute of Historic and Artistic Heritage (IPHAN) in 1943, but has fallen into an advanced state of neglect and decay and is considered abandoned.
Xocó is a dead and poorly attested language or languages of Brazil that is not known to be related to other languages. It is known from three populations: Xokó (Chocó) in Sergipe, Kariri-Xocó in Alagoas, and Xukuru-Kariri in Alagoas. It is not clear if these were one language or three. It is only known from a few dozen words from one Kariri-Xoco elder and three Xukuru-Kariri elders in 1961.

The Riachuelo Formation is a geologic formation of the Early to Late Cretaceous age in northeastern Brazil's Sergipe-Alagoas Basin. It is the first Formation of the Basin to contain sediments deposited under fully marine conditions. The formation is subdivided into three members: Angico, Taquari and Maruim.
The Sergipe-Alagoas Basin is a continental margin basin in the Sergipe and Alagoas states of northeastern Brazil, about 20 to 50 kilometres wide onshore, but with its widest extension offshore, more precisely 13,000 km2 onshore and 40,000 km2 offshore. In general, "Sergipe-Alagoas Basin" refers to the Sergipe and Alagoas sub-basins, but it also consists of the Jacuípe and Cabo sub-basins. Studies of the basin's geology date back to the first half of the 19th century, when J. Henderson in 1821 published preliminary notes on the region's geology.
The Cotinguiba Formation is a geologic formation of Late Cretaceous age in the northeastern Brazil's Sergipe-Alagoas Basin. The Formation is composed of carbonates with clastic intercalations, moreover, the two members dividing it, the Sapucari and Aracaju members, are defined by the proportion of said carbonates. It also possesses a rich macroinvertebrate fauna, of which stands out its bivalve mollucs, gastropods, ammonites, as well as equinoderms and crustaceans.
