A neat example of what is known as a copper skull, this where crystallized copper formed around amygdules. This one is quite unusual as it exhibits multiple skulls instead of usually what one sees is just a single skull. The specimen comes with a previous label from the A. E. Seaman Mineral Museum of Michigan Tech collection as seen at the end of the video.
