Description:

North America, United States, Wyoming, Green River Formation & Lebanon, ca. 53,500,000–48,500,000 years agoo. A collection of approximately 14 fossil fish matrix plates from two of the world's most celebrated fossil fish localities, including pale limestone slabs from the Lebanese Cretaceous deposits preserving elongated fish and shrimp, and cream to gray matrix plates from the Green River Formation of Wyoming preserving Knightia and other Eocene species. Ranging from small study specimens to larger display-quality plates, this is a strong mixed lot for collectors interested in fossil fish from two very different ancient marine and freshwater environments. Size: 3.5" W x 4.75" H (8.9 cm W x 12.1 cm H).

Provenance: private Colorado, USA collection
