The Joggins Fossil Cliffs were named a UNESCO World Heritage Site, spanning more than fifteen kilometres of fossil-bearing cliffs that are witness to more than 310 million years of geological and paleontological riches. Across the Minas Basin from Joggins, in the rocks at Horton Bluff, Sir William Edmond Logan became the first to recognize in North America the tracks of Carboniferous vertebrate animals, in 1841.
