Animal skin, antique, lizard? For crafting (Thorpe St Andrew NR7)

Sorry to have this in my family heirloom craft and souvenir stash;I think maybe from South Africa, but no idea. Thin but a bit rigid, not brittle ( could soften to sew with it) . Two whole skins, one extra piece. Anout 1foot ling, 9 inches wide at widest point. can't bring myself to use it, but animal.long dead so vest to value what's left.
