Description:

North America, Western United States, South Dakota, Pennington County, White River / Upper Brule Formation, Oligocene, ca. 33 to 30 million years ago. A fossilized lower nearly complete jawbone from a prehistoric mammal known as Hyracodon nebraskensis, one of the earliest relatives to modern rhinoceros! The bone is mounted on a wooden display stand with molars, premolars, and a few incisors and fragments. Scientists have surmised from this animal's jaw structure and teeth that Hyracodon were browsers rather than fully grass grazing - the premolars have central cavities that later rhinoceros relatives also had. Hyracodon was a small pony-like ungulate with long, slender limbs for speed, but 3-toes, browsing the open forests and grasslands of North America. Although visually similar to primitive horses, Hyracodon are often referred to as hornless "running rhinos" to indicate their relation to later genera. Size: 8" L x 3" W x 2" H (20.3 cm x 7.6 cm x 5.1 cm); 3.5" H (8.9 cm) on included custom stand.

Provenance: private New Jersey, USA collection, found in Pennington Co, South Dakota, USA on private land in 1970.

SHIPPING LOGISTICS: As a courtesy to our clients worldwide, Artemis Gallery is happy to handle shipping for most lots sold, taking the hassle (and high cost!) out of having to arrange shipping on your own. Shipping costs will be added to your invoice at auction's end based on information given when you registered to bid - we strive to offer the most economical shipping costs to ensure safe transit. Our shippers of choice are DHL for International shipments and UPS for domestic shipments, but we are able to ship via other carriers at the buyer's expense as deemed necessary or by request.

For shipments of oversize items, Artemis Gallery will assist the buyer in working with a third-party shipping provider. For shipments outside of the USA, customs and duties may apply upon entry into said country, and this fee, if any, is the buyer's responsibility. If you have questions about this, please inquire BEFORE bidding.

Items will be shipped only upon receipt of payment in full and will be insured for their full value - no exceptions.
