Pachyrhachis is an extinct genus of snake with well developed hind legs known from fossils discovered in Ein Yabrud, near Ramallah, in the central West Bank.[1] It one of three genera of Cenomanian snakes with hindlimbs. Many of today's modern pythons and boas still have small bone spurs, where limbs would have been millions of years ago. Pachyrhachis snakes would have only been about 1 m (3-4 ft) long.
