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: 5
Claim 1
Independent Claim
137 words
A METHOD OF MAKING A SYNTHETIC FOSSIL COMPRISING THE STEPS OF: PHOTOGRAPHING A NATURAL FOSSIL HAVING A CONTOURED SURFACE TO FORM A COLOR-FAITHFUL IMAGE OF SAID NATURAL FOSSIL, IMPRINTING A SURFACE OF A FLAT-SHEET WITH SAID COLOR-FAITHFUL PHOTOGRAPHICALY REPRODUCED IMAGE OF SAID NATURAL FOSSIL, CASTING A MASTER NEGATIVE OF SAID NATURAL FOSSIL, CASTING A POSITIVE OF SAID MASTER NEGATIVE, FORMING A MALE DIE MEMBER AND A FEMALE DIE MEMBER WITH THE CONTOURS OF SAID MASTER NEGATIVE AND POSITIVE AND WITH COMPLEMENTARY CONTOURS CORRESPONDING TO THOSE OF THE SURFACE OF SAID NATURAL FOSSIL. PRESSING SAID SHEET BETWEEN SAID DIE MEMBERS WITH THE CONTOURS IN REGISTRY WITH THE COLOR-FAITHFUL IMAGE APPLIED TO SAID SHEET TO CONFORM SAID SHEET TO THE CONTOURED SURFACES OF SAID NATURAL FOSSIL AND PRODUCE A THREE-DIMENSIONAL REPRODUCTION OF SAID NATURAL FOSSIL FROM SAID SHEET, AND

Claim 3
Dependent Claim
32 words
The method defined in claim 1 wherein said image is applied to said sheet by screen-printing and said surface of said sheet a pattern-bearing bone and rib configurations of the natural fossil.
Claim 4
Dependent Claim
28 words
The method defined in claim 1, further comprising the step of varnishing selected portions of said image to produce a gloss simulating the gloss of the natural fossil.
Claim 5
Dependent Claim
36 words
The method defined in claim 1 wherein said sheet is paperboard with the weight of 400 to 1000 g/m2 and said die members are pressed against said paperboard at a pressure of 1 to 1000 kg/cm2.
