Maybe those who know that primitive weapons could be used to take down elephants. Ivory was being shipped out of Africa long before firearms were introduced there.
Or were you being sarcastic?
Not being sarcastic - but skeptical. Please inform on the primitive weapons that were used to kill elephants.
It would seem more likely that dead carcasses were scavenged for ivory and meat. i.e. Old, large elephants have bigger tusks. Dead elephants are less risky than agile, live ones.
