Abstract
Abstract A method of producing relief reproductions of natural fossils, especially fossile birds of the Jurassic geological period, wherein a color-faithful image of the natural fossil is applied to a white paperboard surface which is screen printed with a white pattern corresponding to the bone and other hard-portioned patterns of the fossil. From the natural fossil, male and female die members are formed, faithful to the contours of the fossil and are used to emboss the paperboard in registry with the aforementioned image. The relief reproduction thus produced is cut out from the paperboard along the outline of the image and is attached to a natural stone slab, preferably by being recessed in a cavity of similar outline.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
145 words
A method of making a synthetic fossil comprising the steps of: imprinting a surface of a flat paperboard with a color-faithful image of a natural fossil; forming a male die member and a female die member with contours corresponding to those of said natural fossil; embossing said paperboard with said die members in registry with said imaGe to produce a three-dimensional reproduction of said natural fossil; screen printing on the surface of said paperboard bearing said image a pattern representing bone and ridge patterns of the natural fossil and corresponding to regions of greatest embossment by said die members, prior to embossing the paperboard; and cutting the reproduction from said paperboard along the outline of said image and mounting the cut reproduction on a slab of natural stone to form a body having the weight and configuration of the natural fossil in its stone surroundings.
Claim 2
Independent Claim
145 words
A method of making a synthetic fossil comprising the steps of: imprinting a surface of a flat paperboard with a color-faithful image of a natural fossil; forming a male die member and a female die member with contours corresponding to those of said natural fossil; embossing said paperboard with said die members in registry with said imaGe to produce a three-dimensional reproduction of said natural fossil; screen printing on the surface of said paperboard bearing said image a pattern representing bone and ridge patterns of the natural fossil and corresponding to regions of greatest embossment by said die members, prior to embossing the paperboard; and cutting the reproduction from said paperboard along the outline of said image and mounting the cut reproduction on a slab of natural stone to form a body having the weight and configuration of the natural fossil in its stone surroundings.
Claim 3
Dependent Claim
43 words
The method defined in claim 1 wherein said slab is recessed conforming to said outline and said reproduction is secured in said recess, said reproduction being varnished at least at selected portions to produce a gloss simulating the gloss of the natural fossil.
Claim 4
Dependent Claim
38 words
The method defined in claim 2 wherein said paperboard has a weight of 400 to 1,000 g per m2 and said die members are applied against said paperboard at a pressure of 100 to 1,000 kg per cm2.
Claim 5
Dependent Claim
25 words
The method defined in claim 3 wherein said natural fossil is a fossil bird of the Jurassic period and said stone is a Jurassic limestone.
Claim 6
Dependent Claim
74 words
The method defined in claim 4 wherein said die members are produced by: a. forming a reinforced silicone-rubber negative from said natural fossil; b. casting a reinforced self-hardening positive of synthetic resin in the silicone-rubber negative; c. forming under heat and pressure a synthetic-resin negative against said positive; and d. forming a reinforcement hardboard postive in said synthetic-resin negative, said hardboard positive and said synthetic-resin negative respectively constituting said male and female die members.
