Excavations showed occupational deposits reaching down to a depth of 23.6 m (77 ft) with one of the longest sequences of Paleolithic flint industries ever found in the Middle East.

An Emireh point was found at the first stage of this level (XXIV), at around 15.2 m (50 ft) below datum, in association with the hominin mandible Ksar Akil 2.

[7][8][9] The site was rescued from burial under the sludge of gravel-making machines in 1964 by the Department of Antiquities, although is mostly unrecognizable due to quarrying operations with its talus buried under tons of soil.

[10][1] A complete skeleton of a juvenile Homo sapiens, referred to as Ksar Akil 1, or more commonly known as Egbert, was discovered in level XVII at 11.6 m (38 ft) cemented into breccia.

[1] In 1947 a fragment of a maxilla, designated Ksar Akil 2, and referred to as Ethelruda, was discovered in material from level XXVI or XXV, at around 15 m (49 ft), which is stratigraphically deeper than Egbert.

[1] The maxilla was originally described as a "Neanderthaloid" adult female on the basis of its similarity to fossils from Tabun I, Skhul IV and V, Gibraltar and La Chapelle-aux-Saints 1.

For instance, due to its small size and tooth sockets, Ksar Akil 2 has been described as similar to the maxilla Skhul V, which was originally thought to be a Neanderthal, but is now considered to be an archaic Homo sapiens.
