    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.
