In centuries past, most of the mammoth tusks found were turned into ivory jewelry.
I remember an anecdote about a convention (probably in USSR? Russia?) where the meat shipment got hung up somewhere, so the locals were hired to hunt up (literally) enough meat. The food was delicious, everyone raved about it, turned out, they’d found a frozen mammoth and cut it up like Fred Flintstone’s takeout place. Not sure I believe this story, of course.
19th century billiard balls were sometimes carved of mammoth ivory from Alaska, I’ve heard. Scrimshaw of that era sometimes had that origin.
