Mineral: Micro Impact Crater on WIS Bone Fragment
Description: U.S. Western Interior Seaway * 20x view of micro-impact crater on surface of WIS Hadrosaur Jaw fragment. The haversian canal structure commonly identified within fossil bones can still be observed. Note: the melt-rim surrounding the target surface area. This micro impact crater was caused by a high-speed (Fe) particle, lining the impact shaft with melted-fused particles of Fe and many other exotic trace elements.
