    Mioplosus labracoides, Knightia eocaena, Diplomystus dentatus
    Green River Formation, Lincoln Co, Wyoming

    The Green River Formation is renowned for many reasons: the abundance of fish species found in its fossil record, the variety of other flora and fauna, and the superb quality of preservation of the fossils excavated there. Perhaps the most spectacular of its treasures, however, is the rare occurrence known as an aspiration. A fantastic snapshot of prehistory, this is the name given to fossils where one animal has expired in the act of swallowing another; effectively choking to death on its last meal. The pair preserved here are a perch-like Mioplosus, 5½-inch long, with 1½ inches of the sprat-like Knightia protruding from its maw. What makes this specimen even more spectacular, however, is that the pair is closely watched by a 5-inch long Diplomystus, itself also a voracious predator, perhaps cheated out of his lunch. Aspirations are rare enough, but such a natural pairing is extremely scarce, and even by the standards of this renowned locality, the quality of presentation and preparation is superlative: each has superb three-dimensionality to the bony skull and vertebrae with fine detail to the rest of the anatomy, and a warm chocolate brown coloring. A highly uncommon and desirable fossil combination presented on an irregularly-shaped matrix, 15½ x 9 inches.
