This is the largest biface that was found in the Fenn cache. It's a "classic" example of a type that is often referred to as a "platter biface" because of its large round shape. Another name used in reference to these very large bifaces is "biface core" because the large flakes they produce could supply material for a number of different types of tools. The edge trimming on this biface is described as possible platform preparations for setting up further flake removals. The largest Clovis "platter" biface discovered in a cache was found in the Montana Anzick cache. It measured 12 3/8 inches (31.4 cm) long. This example is made of opaque Obsidian and it measures 8 5/16 inches (21.1 cm) long and 5 3/4 inches (14.5 cm) wide.
