Fossil Fish Aspiration
Diplomystus dentaus; Priscacara sp.
Green River Formation, Lincoln County, Wyoming
The superb preservation of the fishes from the 18-inch layer of the Green River Formation in Wyoming is world-renowned. The present fossil fish specimens in matrix illustrate a rare occurrence in vertebrate fossils. The presentation of the fish preying upon another fish, known as an aspiration, tells the story of a dramatic conflict between a Diplomystus dentatus and a Priscacara sp. The struggle was preserved in stone as the dying fish, having attempted to consume its prey, sank to the bottom of an ancient freshwater lake. Framed in exotic wenge wood and fitted with a cleat for wall installation.
Matrix measures 29 1/2 x 17 ¾ x 1 1/2in; Specimen measures 18in
