Mioplosus labracoides
    Lower Eocene, Green River Formation
    Kemmerer, Wyoming, USA

    About 50 million years ago, the northern arc of the Gulf of Mexico was slowly, but completely cut off from the ocean and became a land-locked basin. Fresh-water streams draining into it presented the previously salt water marine dwellers with a choice: Adapt or Die. Many did adapt and the result is a faunal assemblage so diverse that it puts NYC to shame - Stingrays and Shrimp, Crocodiles and Crayfish, Alligators and Apatamyids. One of the denizens was a sleek solitary predator called Mioplosus; a relative of the Perch family. As a hunter Mioplosus was higher up the food chain and consequently, is only occasionally represented in the Green River fossil record. Even less commonly seen are two "Mios," as the diggers call them, together on the same fossil plate. Both of these are adults and perfectly preserved. One measures 13 inches (33 cm) from nose to tail and the other 16 inches (40.64 cm) between the same two points. The fossil plate is enclosed in a wooden picture frame to allow wall hanging as a display option. The lake is now sagebrush country with an occasional moose in the creek bottoms and sad-eyed cows on the flats. They are the current winners of the previous climate change event.
    Overall Measurements: 57.25 x 21.5 inches (145.42 x 54.61 cm)
    Offered at no reserve.

    Estimate: $2,500 - $3,000.
