prob. Gallinuloides wyomingensis
    Green River Formation, Lincoln co., Wyoming

    With their tiny, delicate, hollow bones, birds stand little chance of being preserved in the fossil record. The Fossil Butte in Wyoming, however, is famed for its ability to produce fossil after fossil of the most delicate and rarely-found fauna and flora, preserved in the most incredible detail and condition. The present specimen is superlative even by the standards of the area however: it is the spread-eagled body of a prehistoric galliform bird, first described in 1900, an ancestor of modern chickens, grouse, pheasant, quail and turkey. Somewhat unnervingly, it is lacking its head and long-ish neck, perhaps tucked beneath the body, but the remainder of the creature is preserved to perfection, right down to the tiny curved claws. The bones are all superbly well-defined, those of the arms and legs further exhibiting a remarkable three-dimensionality, bone texture and warm brown patination. The world-class quality of the fossil is only enhanced by its aesthetic positioning, as well as by the presence of a fat-bellied, 3 1/8 inch long Knightia eocena, a common herring-like fish in the 50 million year old network of subtropical lakes of this region. The bird fossil itself measures 5 1/8 inches wide by 7¾ inches long, in soft brown shades harmonizing attractively with the pale cream of the irregularly-shaped 17 x 10½-inch matrix.

    Estimate: $18,000 - $22,000.
