FJD ARG cone 15. Museum specimen from my collection. Patagonia, Argentina. Cerro Cuadrado, Jurassic cone of the species Araucaria but maybe not mirabilis. These are far rarer than the usual Santa Cruz Province cone and are not well understood. They are seen enough to be sure they are a distinct variety, but whether they are a subspecies or a completely different species is unknown. They tend to be fractured but this one is not – it is perfect with attractive deep golden color, some red, and it is very glassy. This may be Araucaria elongata or a variety of cone that has been attacked by fungi. In any event, they are unusual and interesting cones and quite rare. The exteriors always look like this – kind of like a potato. When we could still get Argentine cones, these showed up at a ratio of perhaps one to several hundreds of the usual variety.  94 by 52 mm mirror-polished faces; 47 mm thick together; twelve ounces.  $1250

FJD ARG wood 2. Museum specimen from my collection. Patagonia, Argentina. Cerro Cuadrado, Jurassic wood of the species Araucaria.  I don’t know what more you could ask for in a specimen of petrified wood – it has it all — amazing glassy coloring, well preserved cell structures, an amazing exterior with a weathered deep red/brown patina.  The quality of this piece is amazing. How much more rare is this than a perfect amethyst crystal of the same size? They are essentially the same mineral and this one has captured ancient life in a stunningly perfect specimen. In Petrified Wood on page 39. 10.5 cm tall; 12 by 10 cm mirror-polished face; five pounds and eleven ounces.  $8,500
