Description

    AGATIZED "GEM" DINOSAUR VERTEBRA
    Probably Sauropod
    Jurassic
    Morrison Formation, Utah, USA

    The bones of the giant Sauropods, the largest animals ever to roam the Earth (Brontosaurus, Diplodocus et al), were veined with tiny 'Haversian Canals', a tubular microstructure that served to minimize the overall weight of the giant lizards' enormous skeletons. During the millions of years over which the fossilization process took place, these canals were gradually filled with semi-precious agate, a crystalline variety of quartz that occurs in a wide spectrum of colors. Present here are rich chocolate browns, soft creamy-grays, pale milky blues and a few dashes of striking orange and red. Several sections of the vertebra have been sliced and polished to highlight this wonderful natural phenomenon which, as well as its remarkable aesthetic appeal, also serves the purpose of preserving in perfect clarity the interior microstructure of the bone. The whole piece measures 5 3/8 x 6 x 7¾ inches.


    Estimate: $3,800 - $4,500.
