Joseph Burr Tyrrell, FRSC (November 1, 1858 – August 26, 1957) was a Canadian geologist, cartographer, and mining consultant. He discovered dinosaur (Albertosaurus sarcophagus) bones in Alberta's Badlands and coal around Drumheller in 1884. Canada's Royal Tyrrell Museum of Palaeontology in Alberta was named in his honor. Tyrrell went into the gold-mining business in 1898, a career that would last more than 50 years. He was the mine manager of the Kirkland Lake Gold Mine in northern Ontario for many years starting in 1926.
