A stone that is mined in Manitoba and found in at least one of the most iconic buildings in Saskatchewan is getting some international attention.
Tyndall stone has been named a global heritage resource by a sub-commission of the International Union of Geological Sciences.
Tyndall stone dates back more than 400 million years and is filled with fossil fragments.
It was first used to build the walls and warehouses of Lower Fort Garry in 1832.
It can be found in the Saskatchewan and Manitoba legislatures, the Manitoba Museum and in the centre block of Parliament in Ottawa.
