About
About Wadi Al-Hitan (Whale Valley)
Wadi Al-Hitan (Whale Valley) in the Fayum western desert, 150 km SW of Cairo, is UNESCO's fossil open-air museum: 40-million-year-old Middle Eocene Tethys seabed lithified into clays displaying 400 articulated Basilosaurus isis and Dorudon atrox whale skeletons 21 m long, retaining hind limbs proving whale terrestrial ancestry, plus sirenia, sharks, turtles. Site was island bay in Tethys archipelago. Tourist loop exposeskeletons in situ with glass covers over vertebrae. Fayoum Geosite includes Gehannam and Wadi el Rayan falls.
Why it mattersType-site proving Cetacea evolution retained vestigial hind limbs; most concentrated Eocene marine vertebrate lagerstätte.
