ARG 84. Museum specimen. Patagonia, Rio Negro, Argentina. Cretaceous cycadeoid armor section. This is a slice that is specimen round but for a smoothened five centimeter edge. Diamond patterns are frond bases. Excellent cell preservation. With a good loupe or microscope, you can get lost in a jungle of hundred million year old plant cells. Beautiful, glassy lapidary material. No filler/No glue. 25 cm long by about 10 cm wide; 7 mm thick; 12 ounces. $150

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
