Two Limestone Palm Fossil Sections

Found in Wyoming (American Fossil Quarry, Kemmerer, Wyoming). My friend and I had split open a boulder and discovered two halves of a large palm tree berry fossil. The owner of the quarry as well as other professionals were very excited to see it and had identified it for us. It’s in great condition. The pictures provided of the fossils in the car are covered in dust thats why they look a bit faded.

Palm Tree Berry Leaf Fossil section North America, Wyoming I believe example(s) are Compression and Impression fossils. Compression fossil have plant parts that are flattened and at least some of the original plant material remains. Leaves are often preserved as compression. Impressions (or molds) plant parts are flattened, but all of the original plant material has decayed away. Only the shape or texture of the plant remains, pressed into the mud or sand. Bark is often preserved as an impression. You note the item as a "Palm Tree Berry Leaf" I am unable to find information on a species by that name. Is it a type of seed fern? I can not tell if the palm fronds extend off the slabs. From images, I am unable to identify the plant species. Thus, I cannot give an age range on the fossil. Large sections with detailed fossils are desirable for building interior finishes. An auction sale (as the FMV given here represents) may be less than what could be gained from selling the works with a regional home building contractor in a retail environment. Measurements: 18.9” Height x 36” Length and 19”x Height x 35.6” Length; unknown weight More on plant fossils can be read at the Sam Noble Museum information page: https://samnoblemuseum.ou.edu/common-fossils-of-oklahoma/plant-fossils/fossils-by-plant-group/.
