Iberospinus IPA: [aɪbiːʌroʊs̠piːnʊs̠] or IPA: [aɪbiːʌroʊs̠paɪnʌs̠] (meaning "Iberian spine") is an extinct genus of spinosaurid dinosaur from the Early Cretaceous (Barremian) Papo Seco Formation of Portugal. The genus contains a single species, I. natarioi, known from several assorted bones belonging to one individual. Iberospinus represents one of five known spinosaurid taxa from the Iberian Peninsula, the others being Camarillasaurus, Protathlitis, Riojavenatrix, and Vallibonavenatrix.[1] It is important for its implications of the geographical origin of Spinosauridae and the suggested presence of potentially semi-aquatic lifestyle earlier in the evolution of this clade.[2]
