Triceratops Skull | 2023 | Sotheby's
Specimen shows good condition preserving natural surface detail of the bone. Both the large frill and supraorbital brow horns clearly display numerous pits and deep branching grooves which once housed foramina and nutrient canals that supplied blood to the outer bone sheaths. Reconstructed sections are accurately finished.
Megalodon Shark Tooth | 2023 | Sotheby's
PCS Mine, Lee Creek, Aurora, North Carolina 5⅞ by 4½ inches (15 x 11.4 cm). Large, ivory-cream colored tooth from the front (anterior) upper jaw position as indicated by the symmetry and wide lobes on the compressed root. The surface enamel on both sides have a nicely formed ripple pattern, and the tip is complete showing little wear. Serrations on the cutting edges are sharp, also with little wear.

Campo Del Cielo Meteorite With Natural Hole | 2023 | Sotheby's
Like all iron meteorites, the current offering is more than four billion years old and originates from the asteroid belt between Jupiter and Mars. This extraterrestrial sculptural form was once part of the core of an asteroid that broke apart — a portion of which was pushed into an Earth-crossing orbit. This specimen’s animated surface texture is wrapped in a charcoal patina with russet accents. With a rare natural hole, this is a captivating iron meteorite.
Gems From Outer Space — A Complete Slice Of The Imilac Pallasite | 2023 | Sotheby's
Less than 0.2% of all meteorites are pallasites, a rare type of meteorite whose silicate components crystallized. The meteorite from which this slice was cut was found atop the Andes in the Atacama Desert, the highest desert on Earth. The crystals seen here are the result of small chunks of the asteroid’s stony mantle becoming suspended in the molten metal of the asteroid’s iron-nickel core.
Fossilized Moonfish Plaque | 2023 | Sotheby's
This well-preserved Mene rhombea fossil displays its diagnostic compressed body, extremely long pelvic fins, and wide triangular tail. The specimen has been meticulously prepared in fine detail, exhibiting eye orbits and spinal column. Its irregularly shaped rock plaque is highlighted with soft tan and light gray color tones.
