When in Washington, D.C. in June of 2023, I got a chance to visit the Martin Luther King, Jr. Memorial. The gift shop at the memorial has quite a few fossils in its polished slab floor. They are ammonoids, not sure of their names, time period, or geological formation. Thanks to Christopher Barr of dcfossils.org for letting me know about these fossils.
