I have ordered a 0.94mx0.70m fossil slab I wish to wall mount. Unsure of the exact weight at the moment only that it is pretty darn heavy. The wall I'm planning mounting onto is presumably a plaster layer over concrete (fairly new apartment building). Any advice on methods and equipment best for this without potentially tearing the plaster off? Ideally I'd want something cupping the edges to to hold it in place with minimal overlaps rather than affixing anything directly to the fossil itself to preserve the specimen.
