There’s a Valley of Whales in the Middle of Egypt’s Desert and its Millions of Years Old

The Valley of Whales is one of the most striking fossil sites in the world and is a window into the development of whales and an ancient sea. The Valley of Whales is unique for its concentration and quality of fossils. Adding to their touristic value are their accessibility and the natural beauty of the environment.

The fossils found at the site may not be the oldest but their great concentration in the area and the degree of their preservation is such that even some stomach contents are intact. The presence of fossils of other early animals such as sharks, crocodiles, sawfish, turtles and rays found at Wādī al-Ḥītān makes it possible to reconstruct the surrounding environmental and ecological conditions of the time, adding to its justification to be cited as a Heritage site.

The first fossil skeletons of whales were discovered in the winter of 1902–03. For the next 80 years they attracted relatively little interest, largely due to the difficulty of reaching the area. In the 1980s interest in the site resumed as four-wheel drive vehicles became more readily available. Continuing interest coincided with the site being visited by fossil collectors, and many bones were removed, prompting calls for the site to be conserved. The remains display the typical streamlined body form of modern whales, yet retain some of the primitive aspects of skull and tooth structure. The largest skeleton found reached up to 21 m in length, with well-developed five-fingered flippers on the forelimbs and the unexpected presence of hind legs, feet, and toes, not known previously in any archaeoceti. Their form was serpentine and they were carnivorous. A few of these skeletal remains are exposed but most are shallowly buried in sediments, slowly uncovered by erosion. Wādī al-Ḥītān provides evidence of millions of years of coastal marine life.

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.
