These two contrasting slabs come from the famed Morrison Formation, a Late Jurassic fossil bed in Utah known for producing some of the world’s finest agatized dinosaur bone. The upper piece shows vivid yellow limonite mineralization, while the lower slab is packed with deep reddish-orange cell patterns from iron-rich deposits.
