Mioplosus labracoides and Knightia eocena
    Green River Formation, Wyoming
    The occurrence of an "aspiration" - one fish in the act of swallowing another - is extremely rare in the fossil record, but here is a fine example from the famed Green River Formation in Wyoming. Renowned for its abundance of high quality fish fossils, the formation has yielded over 19 species, of which the ancient perch Mioplosus was one of the predators; here a 5ΒΌ-inch example has been caught in the act of chowing down on a sprat-like Knightia; the smaller fish protrudes 7/8 of an inch from its mouth and presumably choked the larger fish to death, with the result that they are preserved together in death for all eternity. The locality is renowned for the detail of its fossils and the world-class on-site preparators are famed for their ability to render a fossil in an attractive and comprehensive manner, as here. A rare and unusual piece, the pale limestone matrix is stabilized with a plywood backing and measures 6 x 7 1/6 inches.
