Other reports include a single tooth found in Moutier, Switzerland. Originally named by Janensch in 1920 as "Labrosaurus meriani", the tooth was later assigned "Ceratosaurus" sp. (of unknown species) by Madsen and Welles. In 2008, Matías Soto and Daniel Perea described teeth from the Tacuarembó Formation in Uruguay, including a presumed premaxillary tooth crown. This shows vertical striations on its inner side and lacks denticles on its front edge; these features are, in this combination, only known from "Ceratosaurus". The authors, however, stressed that an assignment to "Ceratosaurus" is infeasible as the remains are scant, and furthermore note that the assignment of the European and African material to "Ceratosaurus" has to be viewed with caution. In 2020, Soto and colleagues described additional "Ceratosaurus" teeth from the same formation that further support their earlier interpretation.
