Mayan Lithics

A specimen probably from the Moho Cay Collections at St.John's College in Belize City, or some similar materials from water-submerged, manganese-stained Northern Belize Chert.

Hard to tell from the images what this was...likely something unfinished or reworked.

(the Maya didn't use formal/informal scrapers...at least
in Northern Belize).

Length: 6.88"

Width: 1.75"

Thickness: .42"

It is banded chert. This type of chert, published by Shafer and Dr. Hester about 25 years ago,

is known as Chert-Bearing Zone (CBZ) chert...occurring from about 15mi N. of Belize City to about 45 mi. N. of Belize City.
At the Maya site of Colha, where they have conducted 15 seasons, you have a craft-specialized community spanning
1500+ years, with mass production of formalized tools, like the stemmed macroblade point (they ain't daggers)

Colors: Brown/gray/tan/"honey-colored"

When "black", it is simply manganese-stained...common
along the coast, or in riverine environments
