The length of the arrowhead ranges from 35 to 80 mm, with a mean length typically falling between 50 to 60 mm. The stem, which accounts for approximately one-third to one-quarter of the overall length, measures between 12 to 20 mm. In terms of width, the blade spans 16 to 25 mm, while the stem's narrowest point ranges from 12 to 17 mm. The basal width, as documented by Suhm and Krieger (1954), varies between 15 to 21 mm.
