Fossilized tunnels of worms burrowing through mud. Very dense network of worm burrows. Silty limestone matrix and infilling of tubes. Worm burrows are common from the Cambrian period to the present time. If the specimen was collected in this area, it would be from the Mississippian period.

Fossilized worm burrows in silty limestone matrix. From the Cambrian period, Stephen formation. Represents low energy environment with low volumes of sediments being deposited, thus most burrows are parallel to the bedding planes.

Fossilized worm burrows in impure limestone matrix. Structure of worm tubes are well preserved, tubes made up of mineral calcite. Low energy environment resulting in tunnels being parallel to bedding planes. Small pyrite concretion on one side. From the Cambrian period. Recrystallization in the limestone and orientation in the shale parting suggest low grade metamorphism has taken place.
Poorly preserved worm burrows in silty medium grained limestone. Fairly shallow water environment, close to shore. From the Cambrian period, possibly from the Cathedral formation.
