Chalcedony (var. agate) after Baryte. Measures 3 1/2" by 3" by 2" high. Fully replaced with the red agate that the Cisco-Yellowcat dinosaur bone and Redwood limb sections are so highly prized for. This specimen shows the Baryte crystal shapes still on top of the stone. At one time this would have been a full "ball" of Baryte. Collected by self in spring of 92.
