Fossilized colonial coral, middle Devonian in age. Common throughout North America. Species: Pachyphyllum. Warm shallow ocean environment. Limestone matrix. Has undergone weathering. Coral structure is well defined. Small crinoid fragments exposed on one side. Recrystallization of the rock is occurring is some areas, calcite crystals growing in the vugs (cavities). These types of coral fossils are very common in Western Canada and could have been collected locally.
Petrified wood (chalcedony) with quartz crystals growing in the voids. The original woody structure has been replaced by silty material in some areas. Likely from the Drumheller area, not from the Bow Valley. From the Cretaceous period.

Silicified wood, growth rings very well exposed and displayed. One side is weathered and one side is cut, displaying the rings more clearly. All the woody cells have been replaced by silica.

Silicified wood, growth rings very well exposed and displayed. One side is weathered and one side is cut, displaying the rings more clearly. All the woody cells have been replaced by silica. Minor fracturing. From the Cretaceous period. This specimen is typical of the petrified wood found in the Rocky Mountain House and Edmonton areas.
Silicified wood. Almost completely chalcedony. Well defined growth rings, wood structure is very well preserved. This specimen is typical of the petrified wood found in the Rocky Mountain House and Edmonton areas. From the Cretaceous period.

Petrified bone, dinosaur bone from Red Deer River valley. Mostly silica that is replacing the cells. From the Cretaceous period. This specimen is typical of the petrified bone found in the Edmonton area.
