NEW YORK – A large fossilized Mioplosus labracoides fish, an ammonite Kranaosphinctes with a white shell, and a purplish fossil shark tooth that measures more than five and a half inches will likely earn top lot status at Jasper52’s Fossilized Ammonites, Trilobites and More sale, which will be conducted on Wednesday, September 14 at 11 am Eastern time. Absentee and Internet live bidding will be available through LiveAuctioneers.
In addition to the ammonites and trilobites touted in the sale’s title, its 75 lots include several examples of polished ocean jasper spheres in a pleasing range of colors; a celestite geode; a specimen of florite with deep green crystals, on a matrix; a freeform orange labradorite; a pale purple amethyst crystal cluster with columns that jut out in several directions; a dogtooth calcite; and an iron pyrite cluster that takes the form of several overlapping cubes.
The first highlight is a fossil shark tooth from the Carcharodon megalodon species, dating to the Miocene-Pliocene age and emerging from Indonesia. It measures 14.3cm (5.6in) along the edge, and is described as a “superb and large tooth with near-perfect, natural purplish enamel.” It is estimated at $1,000-$1,200.
A fine representative of the ammonites in the sale is one from the Kranaosphinctes species and the Jurassic era, from Sakaraha, Madagascar. It weighs almost 20 pounds and measures just shy of 12 inches long, and the lot notes state it is a “Very decorative specimen with great inner whorls. Both sides equally beautiful.” Its estimate is $1,500-$2,000.
Completing the highlights is a large, visually striking fossilized fish, embedded in a limestone slab. Found in Kemmerer, Wyoming, it captures an individual of the Mioplosus labracoides species that lived in the Eocene. The fish itself measures slightly more than 12in, and the whole weighs just under seven pounds. “This is one of the less common fishes of the Green River Formation and the specimen is rather large for species,” according to the lot notes, which also state, “The fine details of the teeth, scales, fins and vertebrae are very beautiful.” It carries an estimate of $1,500-$2,000.
