ABSTRACT:
A taxidermic specimen and a method of formation thereof is disclosed. A preliminary negative mold (28) is formed by applying an alginate material to the jaw structure of the animal carcass. Fibers (50) are disposed within the depressions (30, 32 and 34) to provide tooth stains. Tooth-colored acrylic material is alternately poured in layers into the teeth depressions (30, 32 and 34) of the preliminary mold (28). The hardened acrylic teeth (44, 46, 48) are removed and chamfered around the gingival line (40). The teeth are reinserted into the preliminary mold (28) and covered by palate and gum forming fiberglass. Natural appearing colorations are provided comprising selected colored threads (52) near the surface of the gum structure. The composite tooth, gum and palate structure forms the master mold (54). From the master mold (54) a final rubber production mold is formed which is used to construct additional production taxidermic specimens in the same manner in which the master mold (54) was formed.
