46" Wide Fossil Fish Plate (18 1/2" Diplomystus) - Wyoming
The larger specimen on the piece is 18 1/2" long and the second Diplomystus is about 6" in length. The entire slab of rock measures 46x17", is about an inch thick and weighs 130 lbs. We've backed it with a concrete board to add extra support and allow for wall mounting hardware to be easily installed.
Due to the size and weight of the piece, it will need to be crated and shipped via freight. Freight shipping will be additional to the purchase price and will probably run around $300 within the continental US, but be substantially more for International shipping.
50 million years ago, in the Eocene (55.8 mya to 33.8 mya), D. dentatus thrived in lakes fed by Uinta and Rocky Mtn. highlands. A voracious predator and delicious prey, D. dentatus is uniquely entombed in the fine-grained, lime mud of Fossil Lake.
The anoxic conditions at the bottom of Fossil Lake slowed bacterial decomposition, prevented scavengers from disturbing corpses, and most interestingly, suffocated creatures that ventured into the oxygen-starved aquatic layer. The result is a miraculous exhibition of Eocene biota in a subtropical, aquatic community within sycamore forests teeming with creatures such as freshwater stingrays, dog-sized horses, menacing alligators, early flying bats, and one of the first primates.
By the end of the Eocene, Earth developed icehouse climate characteristics and had a change in atmospheric chemistry. The effects of bolide impacts may also have contributed to the eventual loss of flora and fauna at once verdant latitudes.
Today the wonderfully preserved fossils of Diplomystus and other Fossil Lake fauna are collected in several private quarries around Kemmerer, Wyoming. The best preserved fish fossils come from the coveted 18 inch layer. This layer is collected at night under high-powered lights allowing the faint signs of fish under the surface to be more easily observed. These “ghosted” fish then must go through many hours of manual preparation to remove the overlying rock and reveal the Green River fauna in all of it’s glory.
