FJD ARG 39. Museum specimen cone and wood set. Three excellent Jurassic specimens from Cerro Cuadrado, Patagonia, Argentina (that I’ve had stashed away for a quarter century). Jurassic cones of Araucaria and pararaucaria and a bit of wood. High grade specimens in excellent condition. No glues or fillers. The Araucaria cone comprises about 40% of a whole cone and includes the stem attachment. This baby has obviously been wandering around the windswept deserts of Santa Cruz for millennia, developing abundant character along the way. It tells a story that’s 150 million years old. Super hard and solid. (48 mm long, 49 mm wide, and 33 mm thick – 3.4 ounces.) The wood is a gemmy, colorful example – all natural but for one cut and polished end, remarkably preserved – It is a dug-out specimen that appears to have a cone attachment. Super nice wood with top cellular preservation, patterns, and colors, and please note that it’s tiny (23 by 29 mm polished face – 13 mm thick – ½ ounce). The pararaucaria cone is surface-collected and patinaed reddish tan – attractive and complete (38 mm long – 0.2 oz). $250

FJD ARG 32. Museum specimen. Patagonia, Argentina. Cerro Cuadrado, Jurassic unidentified. Rare full round skinny stick section. Complete branch section, as found on the exterior and cut and polished on one end. Salmon-pink-ish patina. Mysterious cells and whatnot revealed on polished face. Probable fungi. No filler – No glue. 15 by 25 mirror-polished face; 8 cm long; two ounces. $100

FJD ARG egg. Museum specimen – dinosaur egg. Patagonia, Argentina. Cretaceous. I got this decades ago from an Argentine dealer. It’s a section of a large dinosaur egg. It is very hard agate with a blue hue. The outer shell portion measures about 6 by 6 cm; it’s 57 mm thick; weight is eight ounces. Super cool. $125

ARG 81. Patagonia, Argentina. Cerro Cuadrado, Jurassic conifer of the species Araucaria mirabilis. Full round slice of Araucaria from the same tree that produced the cones. Beautiful exterior and overall mineralization – like fine China. I included images of the full exterior. It’s all there. No filler – No glue. 13 by 8.5 cm mirror-polished face; 7 mm thick; five ounces. SOLD

FJD ARG 40. Museum specimen cone and wood set. Four excellent Jurassic specimens from Cerro Cuadrado, Patagonia, Argentina (that I’ve had stashed away for a quarter century). Jurassic cones of Araucaria and pararaucaria and a bit of wood. High grade specimens in excellent condition. No glues or fillers. The Araucaria cone comprises about 80% of a whole cone and includes the stem attachment and apex. The fortunate erosion affords a natural glimpse of the gemmy seeds within as well as an appreciation of Nature’s awesome geometry. Wind-polished ivory exterior is flawless, smooth to the touch, and compelling. (58 mm long by 48 mm wide and 29 mm thick – 3.3 ounces.) The wood is a gemmy, colorful example – all natural but for one cut and polished end, remarkably preserved – It is a dug-out specimen that appears to have two cone attachments. Super nice wood with top cellular preservation, patterns, and colors, and please note that it’s tiny (22 by 30 mm polished face – 17 mm thick – ½ ounce). Both pararaucaria cones are surface-collected and patinaed reddish tan – both are complete (or just about as the larger one shows a minute ancient chip). (28 mm and 38 mm long – 0.4 oz between them.) $400

FJD ARG 41. Museum specimen. Patagonia, Argentina. Cerro Cuadrado, Jurassic conifer, likely of the species Araucaria mirabilis or pararaucaria. Every bit of this gem is perfect.

No filler – No glue. 41 by 49 mirror-polished face; 4 cm long; three ounces. SOLD

FJD ARG 43. Museum specimen. Patagonia, Argentina. Cerro Cuadrado, Jurassic conifer of the species Araucaria mirabilis. In a perfect world, all fossil wood specimens would be just like this—A full round limb section, as found, cut near one end, polished on both faces, and perfect. A stunning piece of sculpture built and patinaed by the forces of Nature.
Beautiful exterior and amazing overall mineralization. Top notch cell preservation. No filler – No glue. 24 by 45 mm mirror-polished faces; overall 8.5 cm long; six ounces. SOLD
