This Dovetail point was made by Dan Theus from a
piece of agatized dinosaur bone. It represents one of the rare
lithic materials Dan has used over the years to make his lithic art
points. This point measures 3 1/4 inches (8.3 cm) long.
Most dinosaur bones were fossilized with calcium which
produces a stony appearance and texture that is not useful for
knapping. Agatized bone, like the material pictured above, is
formed when the cellular structure is replaced with silica and
quartz, leaving the bone structure intact giving it a glassy
appearance. Fossil dinosaur bones have been found in a wide range of
colors that were caused by various types of minerals in the
surrounding sediment. Red and dark yellow-gold are two of the more
rare colors. Other colors are brown, blue, bright yellow and black
with splotches of red. In the United States the largest deposits of
agatized dinosaur bone are concentrated in Colorado and Utah.
