Fossil auction brings prehistoric world to life, Dec. 27

Huge ammonite, Jurrassic, Oxfordian stage, 30cm, weight 9.2kg presented on stand, est. $450-$650

NEW YORK – There may not be a written record of Earth’s prehistoric times, but there are some fascinating tangible clues that tell the story of who and what inhabited the planet many millennia ago. All you have to do is hold a fossil or other naturally preserved specimen from ages past to realize there’s only one degree of separation between yourself and a living, breathing primordial creature. Such objects are best obtained from experts, such as those who curated Jasper52’s Dec. 27 auction. Absentee and Internet live bidding are available through LiveAuctioneers.

The 30-lot offering includes beautifully preserved, display-worthy examples of fossilized ammonites, trilobites, eggs and other specimens. The sale opens with huge 30cm Jurrasic, Oxfordian stage Dichotomosphinctes wartae ammonite on a custom stand (shown at top of page). Sourced in Madagascar, it weighs a massive 9.2kg, inclusive of stand. The estimate is $450-$650.

Fossil of Earth’s largest-ever gastropod: Campanile giganteum, 39cm, 4.0kg, est. $300-$450

Immediately following is a fossilized Campanile giganteum (above), the biggest gastropod that ever inhabited Earth. Completely natural, this specimen found in France is from the Eocene Age, Lutetian stage. Estimate: $300-$450.
