Mistaken Point Ecological Reserve is one of the world's greatest fossil sites. It is part of Newfoundland and Labrador, in Canada.

Mistaken Point was so named because sailors found it a navigational hazard on the foggy tip of Newfoundland's Avalon Peninsula. The site is on Canada's Tentative List for proposed UNESCO World Heritage Sites. No-one can visit the fossil site without an official guide; collecting actual fossils may not be done.
