Large Prehistoric Mosasaur Fossil Full Skull
. Estimate: $12,000 - $18,000.
Fossilized Mammoth Tusk on Wood Base
. North America, Northwestern United States, Alaska, Pleistocene epoch (Ice Age), ca. 35,000 to 10,000 years ago. A sweeping arc of deep time made tangible, this fossilized mammoth tusk curves gracefully in a broad crescent, its surface alive with warm striations of cream, honey, and earthen brown formed through millennia of mineralization. Estimate: $9,000 - $13,500.
Medieval Jewish Ritual Stone Panel Double Menorahs
. Europe, Medieval Period, ca. 12th-15th Century CE. Rare Jewish Ritual Stone Panel with Double Menorah Motifs. Carved from a single block of coarse limestone, this exceptional architectural fragment features two deeply recessed menorahs presented in mirror-image arrangement, each rendered with stylized branching arms rising from a flared base. Estimate: $7,000 - $10,500.
Roman Silver Phiale Fortuna / Cybele Bust in Tondo
. Roman, Imperial period, ca. 1st to 3rd century CE. A refined Roman silver phiale centered by a repoussé bust of a mural crowned goddess, identified as either Fortuna or Cybele, both powerful embodiments of protection, prosperity, and the ordering forces of the Roman world. Elegant in form yet rich in symbolic weight, the vessel draws the eye inward, where image and ritual converge. Estimate: $8,000 - $12,000.
Pleistocene Fossil Hyena Skull and Mandible
. Eurasia, Pliocene to Late Pleistocene, ca. 3 million to 20,000 years ago. A fossilized hyena skull and mandible, a grin built for the apocalypse, set in chalk-pale bone and ochre-stained matrix. The cranium is short, broad, and powerfully built: a domed braincase rising behind forward-set orbits, a sagittal crest scoured deep by the anchor of jaw muscles strong enough to render the femur of a horse into splinters. Estimate: $5,000 - $7,500.
Japanese Kano School–Style Screen Peonies on Gold Leaf
. East Asia, Japan, Meiji to Showa period, ca. mid-19th to early 20th century CE. A remarkable six-panel folding screen (byobu) showcasing a panoramic landscape painting in the Kano School style. The composition features lush white and pink peonies, possibly red chrysanthemums, and a bamboo fence set against a flowing river and rocky outcroppings. Estimate: $5,000 - $7,500.
Roman Imperial Silver Cup with Twin Handles
. Roman, Imperial period, ca. 1st to 4th century CE. A finely proportioned Roman silver cup, its softly flaring walls and paired handles giving it the confident stance of a vessel made to be lifted, admired, and used. Modest in scale yet rich in presence, the cup reflects the Roman talent for marrying functional design with understated elegance, allowing form and material to do the talking. Estimate: $4,000 - $6,000.
Rare Fossilized Rugops Raptor Killing Claw - Large!
North Africa, Morocco, Kem Kem Formation, Middle Cretaceous Period, ca. 98 to 93 million years ago. An amazing, fossilized raptor claw, possibly from the Rugops genus of dinosaurs, a rare species that is nearly impossible to purchase! This claw is over 3 inches from the root to tip, perfectly capable of ripping and slashing. Estimate: $4,000 - $6,000.
Plateau Monolithic Stone Wolf Ceremonial Axe
. Native American, Columbia Plateau, Nez Perce or related culture, ca. 1000 to 1800 CE. A wolf rendered in stone at the precise scale where sculpture and weapon become the same object: the long tapering body doubles as the poll of the axe, the rounded pommel at the tail end providing counterweight, while the two splayed legs below anchor the form and likely served as the hafting element. Estimate: $3,000 - $4,500.
Superb Consecrated Tibetan Thangka Yamantaka & Mantras
. Central Asia, Tibet, ca. 19th century CE. A large and vibrantly painted thangka depicting Yamantaka, the wrathful manifestation of Manjushri, surrounded by a halo of flames and encircled by numerous deities and attendants. Estimate: $2,200 - $3,300.
