Description:

North America, Western United States, South Dakota, Pennington County, White River / Upper Brule Formation, Oligocene, ca. 33 to 30 million years ago. The fossilized right humerus bone from a prehistoric mammal known as Hyracodon nebraskensis, one of the earliest relatives to modern rhinoceros! 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: 12" L x 4.75" W (30.5 cm x 12.1 cm); 10.25" H (26 cm) on included custom stand.
