真足蛇學名Eupodophis descouensi)是一種已滅絕的有足蛇種,約存活於白堊紀後期時代。真足蛇擁有兩隻,是一個介乎史前蜥蜴與現代無足類之間的一個進化階段代表物種[1]。從現存化石中可見真足蛇身長約有85公分,距今時間約為92,000,000年前。該化石於2000年被發現,發現地是位於黎巴嫩的一條小村莊al-Nammoura,化石本身藏於一塊石灰岩之中[1][2]

當時的生物家將化石移至格勒諾布爾,運用歐洲同步輻射裝置同步加速器對化石進行X射線探測加以分析研究[3][4]。研究人員判斷,化石中的真足蛇後腿約長0.8英寸,有明顯的腓骨、脛骨和股骨[4]。不過這些骨質都已經有著退化的痕跡,這可能是後足對於蛇類的生活失去了本來的功能所致[4]
