Green River Formation fossil, Fossil Butte National Monument, 2016.
Fossilized plants are much more difficult to identify than living plants because their delicate parts often become separated before they are preserved. The detailed preservation of this unidentified flower is due in part to the fine-grained nature of the limestone matrix in which it is found.
