- Provenance: Kemmerer, Wyoming, USA
- Size: H115cm W77cm D3.5cm
- Age: Eocene, 50 Million Years Old
- Description: Dating to the Eocene (approximately 50 million years ago), including 24 fossilized fish, each in very fine condition and placed on a free-form matrix.
- Additional information: Within the Green River Formation of southwestern Wyoming, in the area known as Fossil Lake, two distinct zones of very fine-grained calcareous mudstones are particularly prized for preserving a wide variety of complete and detailed fossils. These layers are an Eocene lagerstätte, a rare place where conditions were ideal for the rich accumulation of undisturbed fossils. The most productive zone—called the “Split Fish Layer”—consists of a series of laminated or varved calcareous mudstones about 6 feet (1.8m) thick that contains abundant fish and other fossils. These readily split along the layers to reveal the fossils. This thin zone represents about 4000 years of deposition. The second fossil zone, the “18-inch Layer,” is an unlaminated layer about 18 inches (46 cm) thick that also contains abundant detailed fossils, but is harder to work since it does not consist of fissile laminae.
