Wadi Al-Hitan, Whale Valley, in the Western Desert of Egypt, contains invaluable fossil remains of the earliest, and now extinct, suborder of whales, Archaeoceti. These fossils represent one of the major stories of evolution: the emergence of the whale as an ocean-going mammal from a previous life as a land-based animal. This is the most important site in the world for the demonstration of this stage of evolution. It portrays vividly the form and life of these whales during their transition. The number, concentration and quality of such fossils here is unique, as is their accessibility and setting in an attractive and protected landscape. The fossils of Al-Hitan show the youngest archaeocetes, in the last stages of losing their hind limbs. Other fossil material in the site makes it possible to reconstruct the surrounding environmental and ecological conditions of the time.

Brief synthesis The globally important fossils of Wadi Al-Hitan (Whale Valley), in the Western Desert of Egypt, provide dramatic evidence of one of the iconic stories of evolution: the emergence of whales as ocean-going mammals, from their previous life as land-based animals. The World Heritage property is a strictly protected zone, set within the wider landscape of the attractive Wadi El-Rayan Protected Area. It is an exceptional global reference site because of the number, concentration, quality and accessibility of the evidence of the earliest whales, often in the form of complete skeletons, and the record of the environment that they lived in. Criterion (viii): Wadi Al-Hitan is the most important site in the world to demonstrate one of the iconic changes that make up the record of life on Earth: the evolution of the whales. It portrays vividly their form and mode of life during their transition from land animals to a marine existence. It exceeds the values of other comparable sites in terms of the number, concentration and quality of its fossils, and their accessibility and setting in an attractive and protected landscape. Integrity Wadi Al Hitan is of sufficient size to include the main exposures of rocks where the whale fossils are found, as well as associated geological features of interest. In addition, a wider part of the Wadi El-Rayan Protected Area is included in the property, including the immediate landscape surrounding the fossil sites, areas of scenic…
