Diplomystus dentatus & Knightia eocaena
    Eocene, Green River Formation
    Kemmerer, Wyoming, USA

    While fossil fish of numerous varieties are certainly abundant in the layers of the Green River Formation, the occurrence of a large fish in the process of eating and effectively choking to death on a smaller fish - known as an "aspiration" - is indeed a rare phenomenon. In this prehistoric scene, a large Diplomystus was a bit too zealous in its pursuit of a meal, as a smaller but still quite sizable Knightia has proven that it has literally bitten off more than it could chew! Preserved for eternity this pair remain locked in a last meal for both. The large Diplomystus exceeds eight inches in length making it a substantial specimen of this variety regardless of the added bonus of the aspriation phenomenon. Both fossil fish are well preserved with each displaying sharply defined vertebral columns, rib bones and fins. The wood backed limestone matrix has the characteristic mottled gray appearance of the shale from the 18 inch layer of the Green River Formation. This ancient snapshot concretely captures the desperation of this penulitmate event in the lives of both creatures.
