Flaked stone projectile point
Likely worked chert or fine-grained silicified shale; exact lithology cannot be confirmed from the image
AI-generated identification · may be incorrectOpaque dark gray, dull to slightly waxy luster, very fine-grained and conchoidally fracturing; typically Mohs 6.5–7 if chert. The notches and bifacial flaking are deliberate human workmanship, not natural crystal cleavage.

Physical properties
Opaque dark gray, dull to slightly waxy luster, very fine-grained and conchoidally fracturing; typically Mohs 6.5–7 if chert. The notches and bifacial flaking are deliberate human workmanship, not natural crystal cleavage.
Formation & geological history
A shaped archaeological artifact made by pressure/percussion flaking, probably from siliceous sedimentary stone formed millions of years ago; its cultural age cannot be determined visually. It may be an authentic prehistoric point or a modern reproduction.
Uses & applications
Originally used as an arrowhead, spear point, or knife tip; today it has archaeological and collecting interest rather than industrial value.
Geological facts
The triangular outline, bifacial flake scars, and basal side notches are characteristic of a notched projectile point. Typological dating requires provenance, dimensions, technology, and comparison with regional artifacts.
Field identification & locations
Common source materials include chert, flint, chalcedony, and silicified shale; identify by testing a hidden edge for glass-like fracture and inspecting flake scars, but avoid destructive tests. Do not remove possible artifacts from protected sites.
