Fossilized Palm Leaf & Fish Fossil

The Green River Formation of Wyoming produces some of the best preserved and most abundant fossil fish in the world. The unusually excellent preservation of the Green River fish fossils is usually attributed to a combination of two factors: 1) a cold period during the Eocene that would have caused dead fish to sink faster due to a less inflated swim bladder; and 2) the great depth of the lakes and the consequent anoxic conditions that would have often prevented scavengers from disturbing the carcasses.

This one of a kind specimen captures a rarity of a palm tree leaf and surrounding fishes in a uniform horizontal form.
