Marine Lower Lias, with Ammonites bucklandi and other fossils, was recorded in the Wadi Araba by Figari Bey in 1864. No one has since been able to find marine Lias in Egypt, but in 1915 Greco figured a Sinemurian faunule, including an Arnioceras, from the Figari Egyptian collections at Florence, and claimed that Figari's discovery was confirmed. A special search for the locality was made in 1951, without success. The paper reviews the evidence and records Carboniferous rocks and fossils that were found. Some general remarks are also made on the structure and origin of the Wadi Araba.
