Since 1978, Skullduggery has produced and distributed museum quality fossil replicas to museums and natural history enthusiasts throughout the world. The majority of replicas manufactured by Skullduggery are molded from original fossil material housed at major museums throughout the country. From the original specimen we create a detailed mold and then hand cast a full-size replica. Our proprietary molding and casting process duplicates the intricate details of the original with remarkable accuracy; the sutures, muscle origins and fine cranial pitting is clearly visible. Educational booklets are provided for most of our replicas!!
