Camarasaurus lentus, Leg Bone Section
    Late Jurassic, 144-156 Million Years Old
    Grand County, Utah

    Dinosaur bone can fossilize in many ways, but when superheated water passes through layers of rock due to geothermal activity it can deposit silica in the porous marrow of the dinosaur bone leading to complete agatization. These agatized bones are essentially infilled with the mineral quartz or silicon dioxide which can pick-up a variety of colorful minerals that were dissolved in the superheated water - this mechanism is commonly referred to as "hydrothermal deposition". These colorful agatized dinosaur bones are highly prized by collectors who avidly search for them in the remote Utah deserts. The most prized colors by collectors are red and yellow. Here we have an exceptional "pigeon-blood red" specimen of exceptional beauty with an incredible white and gray quartz center, some orange areas in the marrow cells, and a dark gray to black rind around the edges. The colors in this piece perfectly complement each other, giving it an irresistible, eye-catching appearance and allure. Measures 6 x 5 1/4 x 2 5/8 inches thick.

    Estimate: $2,500 - $3,000.
