Turkey-tail

1500–500 BCE, Adena

The Turkey-tail is a large Early Woodland ceremonial blade of the Midwest, about 1,500 to 500 BCE, associated with Red Ochre and early Adena burials. It was almost always made of blue-grey Upper Mercer or Wyandotte chert and cached in graves. It is among the most valued Woodland objects.

Diagnostic traits

Large lenticular blade with shallow notches producing a short pointed base that resembles a bird's tail; typically Upper Mercer chert.

Identification

Turkey-tail has a large lenticular blade and shallow notches that produce a short pointed base resembling a turkey's tail, unlike Adena, which is stemmed, and Meadowood, which is narrow with low notches. Varieties by Harrison, Fulton and Hebron are recognised. It is thin and finely percussion-flaked.

Reproductions and fakes

Turkey-tails are faked in Upper Mercer chert because of their value, and fakes often exaggerate the tail or are too thick; genuine examples have a soft surface patina and often red ochre staining. Provenance from a documented cache is the best support.
