One of the most noticeable elements is the so-called Amoudian elements, that are the first known stone blades ever. Nevertheless the connection of this Amoudian innovations with later Upper Paleolithic blades is most likely null.
The thick layers of Jabroudian consist mainly in heavy scratchers and hand axes. The proportion of the first type of tools tends to increase as time passes, while the axes show a decrease even totally disappearing in the upper layer of some Jabroudian sites.
A most interesting facet of Jabroudian culture are the so called Amoudian blade tools. This is the earliest known stone blade industry ever and it's always found inserted in Jabroudian sites, with both "cultures" being inseparable. As with the hand axes, the proportion of stone blades decreases with time, until it finally vanishes with the end of Yabrudian culture.
There is a gap of c. 10,000 years between the end of this blade tradition and the appearance of Upper Paleolithic technology, based precisely on stone blades.
End of Jabroudian
