Lutetium is the last of the lanthanides. It’s another not so rare “rare-earth” metals. Being almost as common as silver in the earths crust but significantly more difficult to process and thus expensive. It’s main use is in determining the age of other minerals, as its isotopes decays in a very predictable pattern and length that gives it an edge over other isotopes. It’s paired up with Hen Harrier as they both share naming issues, the Hen Harrier called many different names throughout Europe, it’s the same with Lutetium which also had many different names in Europe until recently.

Hafnium is a return to the transition metals, it’s used in computing and neutron capture rods in nuclear reactors. It’s resembles Zirconium and is often mistaken for it.

The danish landrace goat bread out of domesticated and wild goats in Denmark. It is often mistaken for other breeds of goat. It’s tied to Hafnium as they both get mistaken often.
