Subtle zoomorphic forms detected by archaeologists in California, The Netherlands and France

For me, the fossil shell inclusion may be taken as the "breath" of the horse head (facing left) or as "whiskers" on a feline animal in another interpretation of the imagery. Scallop shell fossils seem to have been significant to some Stone Age peoples as they are seen as featured components in many artifacts such as the West Tofts, England, handaxe and two scallop shell shaped artifacts from Licking County, Ohio, seen on this blog.
