Tyndall Stone is highly fossiliferous and the fossils contribute to its aesthetic appeal. It contains numerous fossil gastropods, brachiopods, cephalopods, trilobites, corals, stromatoporoids, and others. The mottling results from burrowing by marine creatures that occurred during and shortly after limestone deposition.[4] The identity of the burrowing organisms is not known, but fossil burrows of this type have been given the name Thalassinoides.[2]
The Tyndall Stone quarry is operated by Gillis Quarries Ltd. and is located approximately 40 kilometres northeast of Winnipeg, Manitoba. The quarry has been in operation, and owned by the same family, since 1910.[8]
