Oxalaia (the name is a reference to the African deity Oxala) is a genus of large carnivorous theropod. It was a large theropod species from Spinosauridae family; which lived during the late Cretaceous period (in the early Cenomanian stage, about 98 mya) on the continental landmass, that is now, South America, Brazil.

All known Fossils of Oxalaia recovered in 2004 from the Laje do Coringa locality of the Alcantara Formation, from the São Luís Basin; part of the Itapecuru Group. Besides these bone fragments, numerous instances of 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 14.5 meters (39 to 46 ft) in length and 5.5 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; several known fossils, albeit not all, are destroyed by fire that happened on the national history museum of Brazil.

The Oxalaia's dietary preference was; similiar to other known Spinosauroid species, a Generalist Carnivore. It will eat any source of Meat but likely had pereference for animals around water.

It was speculated that Oxalaia might be a sub-species of Spinosaurus; although it's possible its only presumption; its also consider it very unlikely due to higher geographic distance.

The only known Oxalaia fossil

In the Media

  • It’s possible that the Spinosaur pronounced as an Empirosaur in Terra Nova might be an adult Oxalaia. Since the Horned Carnotaurus also Featured In the show, was also a Dinosaur that lived in South America.
