Petroglyphs (also called rock engravings) are pictogram and logogram images created by removing part of a rock surface by incising, picking, carving, and abrading. Outside North America, scholars often use terms such as "carving", "engraving", or other descriptions of the technique to refer to such images. Petroglyphs are found world-wide, and are often associated with prehistoric peoples. The word comes from the Greek words petro-, theme of the word "petra" meaning "stone", and glyphein meaning "to carve", and was originally coined in French as pétroglyphe.

The term petroglyph should not be confused with pictograph, which is an image drawn or painted on a rock face. Both types of image belong to the wider and more general category of rock art. Petroforms, or patterns and shapes made by many large rocks and boulders over the ground, are also quite different. Inukshuks are also unique, and found only in the Arctic (except for reproductions and imitations built in more southerly latitudes).

Shane Wilson is a sculptor who has lived and worked in Yukon and British Columbia, Canada. His principal mediums are antler, horn, ivory, and bronze, from which he creates sculpture in his signature style, a juxtaposition of abstract organic and non-organic shapes, best seen in his moose skull sculpture "Duality".

Originally beginning with other art forms which included drawing, acrylic painting and clay sculpture, his interest in antler carving was sparked in 1985 when he attended a show of antler carvings by Maureen Morris, a well known sculptor from Atlin, British Columbia.

After moving to the Yukon in 1987, Shane began experimenting with antler carving and found great creative and tactile potential in the medium. He has since worked in antler, bone, horn, mammoth tusk, stone, and now bronze.

His bronze series entitled "Skullpture" includes cast, carved skulls of moose, wolf, seal, grizzly and black bear, human and wolverine.

Shane has taught the art of antler carving during Red Deer College's "Series: Summer School of the Visual Arts".
