These mineralogical differences reflect diverse cooling environments and internal processes within the parent body
Studying this species provides important insights into the early evolutionary history of lagomorphs and the development of traits seen in their modern descendants
Some varieties fluoresce blue or red under UV light
whose internal melting and magmatic activity produced a layered structure similar to that of small terrestrial planets
