This chert trihedral-like arrowhead is from Mleiha, Sharjah, United Arab Emirates.  The arrowhead dates to ca. 5100-7000 BP.  Scale approximate.


‘Trihedral’ refers to the triangular cross-section shape of the distal end of the point.  The cross-section is made by relatively flat pressure flaking on one surface followed by very steep pressure flaking on the opposite surface, creating a prominent ridge down the centre of the face.  The point in this model is biconvex rather triangular in cross-section, but the elongated and shouldered shape is a typical variant of trihedral arrowheads.  The stem on this point is broken.

The arrowhead is curated by the Sharjah Archaeology Authority.
