An Elk in Europe is a moose in North America. So I am assuming they’re actually moose bones, not wapiti bones?
The North America wapiti we call an elk is called a red stag in Europe (Hartz in German).
I once belonged to the US military’s Kaiserslautern Rod and Gun Club in Germany, and to get a German hunting license you had to just about be a biologist on European game animals to pass the licensing test....
Hirsch in German... Not hartz.
