Lepisosteus simplex, Knightia eocaena
    Green River Formation, Lincoln Co., Wyoming, USA

    The Green River Garfish is one of the very rarest species in the abundant fossil record of the Fossil Lake area, and also one of the largest fish species. Related to the modern-day Alligator Gar (Lepisosteus spatula) it was a slender eel-like creature with an elongated toothy snout; in addition to this effective predatory weapon, the body was encased in tightly-layered, armor-like scales, making it a formidable presence in the 50 million year old waters as it prowled around, preying on other fish. It was most probably found basking near the surface and, unusually, often breathing the atmospheric air. This is a truly exceptional specimen, with superlative detail, preservation and three-dimensionality, even by the standards of this world-renowned locality. The whole fish is exquisitely presented, from the row of tiny teeth in the bony head, via the serried rows of ganoid scales, to the tiny bones of the dorsal, anal and caudal fins. The diamond-shaped scales have a wonderful enamel-like sheen, and the whole fossil is colored a lovely warm chocolate brown, 17¼ inches long. Joined by four of the lakes' abundant Knightia, sprat-like snacks for the Gar, it swims across a creamy limestone matrix, 31⅛ x 23 inches.
