A stunning example of a fossilized Mastodon (Mammut americanum) tooth dating approximately 11-30 million years ago during the Late Miocene to Late Pleistocene epochs. The tooth characteristically features high ridges (Mastodon means "nipple tooth") beneficial for a diet heavy in woody sticks, twigs, brush, and other fibrous items requiring aggressive chewing and grinding. Excavated from the Peace River area of Florida, circa the 1960s, this lower molar tooth remains attached to a sizeable portion of the mandible, as shown. Close examination of one end reveals a significant portion of root, as well as the fossilized inner bone matrix. Specimen measures approximately 14" x 6.5" x 10" tall with a weight of 17lb, 9.7oz, or 7.986 kilograms—an impressive and very scarce specimen, displaying a wonderful array of colors the area is known for.
