Ksar Akil 1 or more commonly known as Egbert is a complete skeleton of a juvenile Homo sapiens that was discovered in level XVII at 11.6 m (38 ft) cemented into breccia. At the time of death, Egbert is estimated to have been 7 to 9 years old and may have been female due to its small size. Egbert was covered by a pile of cobbles, which may indicate deliberate burial. A second maxilla and some rib fragments were discovered nearby the burial, which indicates a second individual may also have been buried in the same place.

Egbert is known only from descriptions, photographs, and reconstructed casts of the skull, now in the National Museum of Beirut, after being studied in America. Ewing gave Egbert's skull to the National Museum of Beirut, and it's unknown what he did with the rest of the skeleton, but both parts became subsequently lost.

Radiocarbon dating and Bayesian modelling supports Egbert's age range of 40,800 to 39,200 years BP.
