Joan Rennick found a spearhead seven years ago at Cape Spear and thought it would be a good piece of jewelry, so she kept it, the Canadian Broadcasting Corp. reported.

Rennick subsequently saw a spear head in National Geographic that looked very similar to hers, and began to understand how old hers could be.
