Bone knife from Morocco is the oldest specialized bone tool associated with the Aterian culture
A single bone artefact found in a Moroccan cave is the oldest well-dated specialized bone tool associated with the Aterian culture of the Middle Stone Age, according to a study co-authored by Prof Nick Barton and Dr Jean-Luc Schwenninger.
The tool was recovered in 2012 from Dar es-Soltan 1 cave, located about 260m inland from the Atlantic coast of Morocco. Upon close examination, the team of scientists were able to identify the origins of the bone as a large mammal rib with evidence of having been shaped and sharpened into a knife measuring at just under 13cm long through a complex series of modifications. The layer containing the bone knife has been dated to approximately 90,000 years ago, approximately 55,000 years after the first appearance of the Aterian culture.
