Oxalaia (a reference to the African deity Oxala) is a genus of carnivorous theropod. It was a Spinosauroid which lived during the late Cretaceous (early Cenomanian stage, about 98 mya) in what is now Brazil.
Fossils of Oxalaia were recovered in 2004 from the Laje do Coringa locality of the Alcantara Formation, part of the Itapecuru Group of the São Luís Basin. Besides these bone fragments, numerous spinosaurid teeth had earlier been reported from the site. The genus was named by Alexander Wilhelm Armin Kellner, Sergio A.K. Azevedeo, Elaine B. Machado, Luciana B. Carvalho and Deise D.R. Henriques in 2011 and the type species is Oxalaia quilombensis. The specific name quilombensis refers to the quilombo settlements, such as on Cajual Island, which was founded by escaped slaves. Estimates suggest that it was 11.9 to 14 meters (39 to 46 ft) in length and 5 to 7 tonnes (5.5 to 7.7 short tons) in weight. It is the largest theropod known from Brazil and the eighth officially named species of theropod from Brazil. In 2018; all known Oxalaia fossil is destroyed by the fire that happened on the national history museum of BrazilIts diet is like any known Spinosauroid Species, a Generalist Carnivore; It will eat any source and kind of Meat but Prefers Aquatic-based organisms. It is speculated that Oxalaia might be subspecies of Spinosaurus; although it's possible its presumed highly unlikely due to geographic distance.
