Discovered in the fossil-rich shales of Utah, Colorado, or Wyoming, the leaf is preserved in fine lakebed sediments that faithfully record its graceful outline and radiating venation. The smooth compression and natural dark tonality reflect the calm, oxygen-poor conditions of the ancient lake floor where it settled millions of years ago.\u003c\/p\u003e\n\u003cp data-start=\"705\" data-end=\"1089\"\u003eDuring the Eocene, this region supported expansive freshwater lakes bordered by flourishing subtropical vegetation.
