This Walrus Skull in a European Museum Explains What Happened to Greenland's Vikings

For centuries, mainstream history assumed Greenland's Norse colonists starved because they stubbornly refused to adapt to the freezing North Atlantic environment. But 67 pieces of medieval packing waste, discarded walrus skulls scattered across European museum collections, tell a radically different story of a specialized hunting economy, resource exhaustion, and global market collapse. Rather than an isolated farming community failing to adjust, the colony operated as a commercial enterprise reliant on exporting luxury ivory to Europe in exchange for essential imports like iron and timber. As centuries of overhunting depleted local herds and forced hunters into hazardous northern waters for smaller animals, a sudden market crash driven by West African elephant ivory coincided with rising sea levels that swallowed vital coastal pastures, bringing a quiet end to the settlements.
