Fossil Fish - Fossil plate matrix - Diplomystus Dentatus - 8 cm - 12.9 cm

In this lot, a fairly large fossil fish is being auctioned on a lithographic limestone plate of the species Diplomystus Dentatus. The plate measures 8 cm tall and 12.9 cm wide, and the fish body is 11 cm long. Perfect preservation, natural and complete specimen, "it's an exquisite piece". It comes from Wyoming, from the famous beds of the Green River Formation in the United States. Diplomystus was a freshwater fish of medium to large size, capable of reaching up to 70 cm in length, a generalist predator with a high-set mouth that inhabited near the surface to catch its prey; other fish such as Knightia species, aquatic insects, crustaceans, and any other prey smaller in size. The Green River Formation, extending across the states of Wyoming, Utah, and Colorado, is the result of sedimentation of a vast region of lakes that, due to various geological events, produced very fine clay and silt that were low in oxygen, contributing to exquisite fossilization including soft parts of a large number of animal and plant species, as well as insects. An iconic site in paleontology for the quantity and quality of its fossils. "This specimen comes with an L-shaped acrylic display stand as a gift"
