Nizar Ibrahim (born in 1982) is a US-based German-Moroccan vertebrate paleontologist and comparative anatomist. He is currently an assistant professor at the University of Detroit Mercy. Ibrahim has led several expeditons to Africa's Sahara and is notable for his research on fossil vertebrates from the Kem Kem Group, including pterosaurs, crocodyliforms, and dinosaurs.[1][2][3] In recent years, research led by Ibrahim radically changed ideas about the morphology and life habits of one of the largest predatory dinosaurs, Spinosaurus aegyptiacus.[4][5] Ibrahim also has interests in bioinformatics and contributed to the NSF-funded Phenoscape project.[6] He regularly engages with the public and is a speaker with the National Geographic Speakers Bureau.[7][8][9]
