Two of the fragments are in a triangular prism shape, remaining three have irregular shapes. The individual cells in the center of the fragments are distinct and range in color from white calcite to many shades of brown all the way up to rust orange. Truly impressive paleontological evidence of extinct prehistoric life preserved in geologic context. Smallest piece measures .75" x 1" x 4.25", largest is 1.5" x 4.25" x 6". Collective weight is 4lb, 4oz.
