Carbon dating of walrus bones found in Snæfellsnes peninsula indicates that the bones are at least 2000 years old. A large number of walrus skulls and walrus tusks have been found around Garðafjara beach on the south coast Snæfellsnes. The first skull was discovered 1884. All in all the bones of 50 walruses have been found, most in the past 50 years. Biologists argue this indicates Snæfellsnes was the home of a sizable walrus colony prior to the settlement of Iceland.
A previous theory, explaining the concentration of bone discoveries, speculated they came from the wreck of a ship which had been carrying walrus bones to Europe. However, the existence of a large walrus colony in Iceland would have meant the accumulation of walrus skeletons and skulls which would have been discovered by the Viking age settlers of Iceland.
Hilmar J. Malmquist, the chief of the Icelandic Natural History Museum points out in an interview with the local newspaper Fréttablaðið that such graveyards of walrus bones could also explain references to walruses in Icelandic place names, shedding light on the possible use of walrus ivory by the early settlers of Iceland who could have had access to domestic ivory found in such bone yards.
