A reappraisal of Jeddaherdan aleadonta (Squamata: Acrodonta), the purported oldest iguanian lizard from Africa

Jeddaherdan aleadonta Apesteguía et al., 2016 is currently known as the first and single Mesozoic iguanian lizard from Africa. The original description age of holotype only specimen (i.e. a dentary fragment bearing five teeth) are revised here. We show that this fragmentary was misinterpreted anatomically, does not come Cretaceous beds but instead Quaternary in age, must be assigned to an indeterminate species Uromastyx (spiny-tailed lizards). Therefore, genus considered junior synonym Uromastyx, J. (= sp.) nomen dubium. Our results refute presence lizards Africa have major implications for reconstructing evolution palaeobiogeography group.
