"Gem" Dinosaur Bone
    Jurassic, Morrison Formation
    Utah, USA

    As a piece of "gem" Dinosaur Bone, this is absolutely superb. It is a perfect size, with a polished, glassy surface of completely agatized red bone measuring 5.2 inches (13.2 cm) across. The internal cell structure is easily visible, as numerous marrow spaces and blood vessels have been preserved in brilliant vibrant red, bright orange, and saffron mustard hues. This is just about as good as it gets. An ideal example of "gemmy" red, agatized bone. The rough natural sides under the smooth surface are amazingly rich, as well, and lean towards even a pinkish color in several areas attesting to the quality of the bone all the way through the 2.8 inch (7.0 cm) thickness from top to bottom. This specimen is spectacular as it is, but it could be considered quality "cutting rough." Not surprisingly, the Morisson Formation of Utah has provided this high grade material.
    Overall Measurements: 5.2 x 4.0 x 2.8 inches (13.2 x 10.2 x 7.0 cm)
    Offered at no reserve.
