The result of a collision between a meteorite and the moon that knocked loose a piece of the lunar surface, NWA 8641 Lunar Meteorite: Large Piece of the Moon (estimate: $300,000-500,000) is a massive (7-1/2 inches long and 6.4 pounds) matchless end piece of a lunar meteorite. Similar samples brought to earth by Apollo astronauts are deemed property of the United States government and controlled by NASA at the Johnson Center and at the Smithsonian Institution, but this samples organic separation from the moon allow it to be offered to the public. One of the larger meteorites on record and the 8,641st meteorite recovered and classified in Northwest Africa, it is recorded in the Meteoritical Bulletin. This sample is extremely fresh, and not weathered, and therefore has not been terrestrialized through exposure to the Earths elements. Only about 750 pounds of lunar material including that brought back by astronauts and that which fell in the form of meteorites exists on earth, more than six pounds of which is found in this lot.
From the state whose residents take pride in the notion that bigger is better comes The Largest Mass of the Largest Stone Meteorite Found in Texas Clarendon (c) (estimate: $25,000-35,000). This mass, the discovery of which is detailed in the Meteoritical Bulletin, is now a centerpiece at the Monnig Meteorite Gallery at TCU in Fort Worth. Discovered in West Texas, the 345-kilogram Clarendon meteorite, from the asteroid belt between Mars and Jupiter, was the largest ever found in the state and the third-largest ever found in the United States. The discovery coincided with the recovery of additional fragments, of which this is the largest. Accompanied by a custom display armature, this specimen is characterized by patches of caliche that accent the milk chocolate-colored matrix of the largely flat example with a parallelogram-like that naturally cleaved off the main mass of the meteorite.
A Ceratopsian Dinosaur Skull (estimate: $200,000-300,000) is the most complete known specimen of its kind from the Late Cretaceous of the Hell Creek Formation in North America. The half skull of an unidentified Ceratopsian species measures 88 inches from the tip of the beak to the back of the squamosal, and is different from other Ceratopsians including Triceratops horridus and Triceratops prosus in part because of its large and narrow nasal horn, the relatively short brow horns and a frill (shield) that is relatively small in relation to the rest of the skull. Experts believe the differences between this Ceratopsian and other Late Cretaceous Ceratopsians should help facilitate the naming of a new genus and a new species. It was collected in 2012 and prepared by Neal Larson, who dedicated an estimated 1,200 hours to the preparation and mounting.
Among the most fascinating lots offered in the auction is a Dire Wolf Skull (estimate: $30,000-50,000). The fearsome dog has been called the canine version of the saber-tooth cat. Similar in size to the largest of modern gray wolves and a likely pack hunter with a hypercarnivorous lifestyle, the Dire Wolf disappeared at the end of the Ice Age like most of the giant mammals of the Pleistocene. Scientists believe that these powerful predators, who were represented by the dogs on HBOs Game of Thrones, supplemented their fleshy diet by crushing bones in order to extract nutrients from the marrow. Unlike many specimens, which have been found in California tar pits, this one-of-a-kind collectors specimen was found near the Nodaway River in Page County, Iowa. The skull consists of a maxilla and a mandible, which was fully reconstructed. The major part of the 11.31-inch, museum-quality skull is in exceptional condition, having been preserved with roughly 90 percent of the original bone material intact.
A huge (4.31 by 2.97 by 1.54 inches and nearly 20 ounces) Gold Nugget (estimate: $40,000-60,000) from Victoria, Australia, is a dazzling specimen in a class with few peers. The specimens beautiful natural form and vibrant luster make it a perfect collectors piece, augmenting its rare combination of size, shape and the brilliant color often associated with Australian Gold. Its consistent appeal means any side could be the primary display.
Another large Gold Nugget (estimate: $25,000-30,000) comes from Eagle Creek in the Circle Mining District in Alaskas Yukon-Koyukuk Borough. With right golden coloration and atypically clean appearance, it weighs 12.5 troy ounces. Measuring 3.19 by 2.52 by 0.74 inches, the nugget has one concave and one convex side, each with an intriguingly complex texture.
Cut from a Brazilian large gem-quality rough specimen, this 402.22-carat Aquamarine (estimate: $200,000-300,000) comes from the world-renowned Minas Gerais region of Brazil, which is famous for minerals. This massive rectangular, emerald step-cut investor-grade rarity features a rich greenish-blue hue and crystal clarity.
A 42.3-carat Imperial Topaz (estimate: $50,000-70,000) hails from the same Minas Gerais region of Brazil. From the rarest of the Topaz family, the size, alone, makes this sample an absolute rarity. In an elongated cushion shape with a modified brilliant cut, it displays the iconic deep golden yellow hue, which is found only in Brazils Ouro Preto district. Cut and polished to create an abundance of scintillation, it is accompanied by a GIA (Gemological Institute of America) certificate.
