Fossils


A partial mammoth tusk collected on Melville Island during the CAE is one of the most significant fossils collected in the north. Representing the northernmost specimen of mammoth ever found, this fossil tusk (originally 36" long x 5.75" diameter near the base) has been described and analyzed in a number of scientific papers. A portion of the tusk was cut off one end and used for radiocarbon dating, allowing scientists to determine that the tusk is about 22,000 years old. The significance of the tusk was diminished by the lack of precise information on exactly where it was found. The only locality reference, "near Cape James Ross," suggested the tusk could have arrived on the shore with moving ice. Fortunately, the time and precise place of collection were discovered during the research for this virtual exhibition in 2002, making the specimen even more valuable to palaeontologists. As recorded in Aarnout Castel's diary for September 1916, the tusk was picked up inland from the coast, in the riverbed near "Storkersen's Camp" near Peddie Point on Liddon Gulf:

"The four of us [Castel, Split, Pete, Storkerson] brought the two sledes [sic] into camp. Coming along the river I found a piece of mastadon or mammoth tusk about 2 feet long and 6 inch diameter" (Castel diary, September 14, 1916).
