North America, Wyoming, Green River Formation, Eocene Period, ca. 53.5 to 48.5 million years ago. A stone matrix containing a fossilized plant inlaid with 2 prehistoric fish fossils! The once swampy region had abundant vegetation that were preserved along with other living organisms; these fish were extracted from the famous fossil-bearing "18-inch layer," where the sediment is highly laminated and inlaid next to the plant to provide context and indicate the aquatic environment. The stone is meticulously prepared with a wood panel backing as an amazing display piece. Size: 13" L x 1.25" W x 21.5" H (33 cm x 3.2 cm x 54.6 cm)

The sediment from the Green River Formation was deposited over a 5-million-year span, the layers of flora and fauna may not have fossilized at the same time - but make for interesting composites. The Eocene world was the warmest of the Cenozoic (our current era), with an average mean temperature around 86 F (30 C) (for comparison, the average mean temperature in the last seventy years is around 58 F (14 C). Although the map of the Earth's surface would have been very recognizable to us today, with most of the continents in place and India moving close to its current position, there were basically no ice caps and huge swaths of the landscape were covered with water, including vast inland seas. This impressive aquarium like arrangement creates a rare scene from a prehistoric environment that was drastically different than what the semi-arid Wyoming landscape of today!
