Exhibit-ready high relief footprint, rain. El Pueblo early Permian, NM, USA. - $39 - (Ribera, NM)

Rain slab is almost 1/4 inch thick; footprint (indeterminate) is 1/4 inch thick. Both on clear acrylic stands. Nice mementos of the gathering of continents 285 million years ago. Because continents are like icebergs, with greater volume below the water, narrow oceans prevailed between continents, assuring a supply of rainfall across the equatorial belt of Pangea, the super continent.
