Summary
[edit]DescriptionMioplosus labracoides fossil fish (Green River Formation, Lower Eocene; Fossil Lake Basin, southwestern Wyoming, USA) (15335281280).jpg |
Mioplosus labracoides Cope, 1877 fossil fish in lacustrine marlstone from the Eocene of Wyoming, USA (16.7 cm across). The Green River Formation of Utah-Colorado-Wyoming is famous for having vast oil shale deposits and for having exquisitely-preserved fossils. Fossil Butte National Monument in southwestern Wyoming preserves and displays some of these high-quality fossils. Leaves and fish are the most common large fossils in the Fossil Lake Basin of the Green River Fm. Mioplosus is a fossil perch. It was a predator, mainly feeding on the common, smaller fish Knightia. The Mioplosus shown here has a partially digested Knightia visible in its stomach - most of the Knightia’s vertebral column and the proximal ribs are still present. The brownish area just below the Mioplosus backbone may be a remnant of the Knightia’s head, but I’m not sure. Classification: Animalia, Chordata, Vertebrata, Actinopterygii, Perciformes, Percidae Stratigraphy: Eighteen Inch Layer, Fossil Butte Member, Green River Formation, upper Wasatchian Stage (Wa4)/Ypresian Stage/Lostcabinian, Lower Eocene Locality: Fossil Lake Basin, southwestern Wyoming, USA |
