  • American Mastodon
  • Pleistocene Age
  • Width: 6 ft. – body
  • Height: 9 ft.
  • Length: 16 ft. 6 inch – Tail to tusk tip
  • This well preserved Mastodon was discovered in a peat bog in Michigan. It was actually found with a fetal calf which sadly was unsalvagable.  This female mastodon was around 23-year-old. It shows evidence of paleo Indian butchery!  This specimen was approx. 90% complete and had to have approx. 10% restored. Actual bones from another Mastodon were utilized when possible during the restoration process.  It will come with photos of the actual excavation. This specimen comes with the custom-made steel frame as seen in the photos.  Most of the bones are removable from the armature for study purposes.  This specimen has a custom-made crate for safe and secure shipping.  (The actual shipping cost will be determined based on the location it is being shipped to.)

Mastodons are any species of extinct mammutid proboscideans in the genus Mammut, distantly related to elephants, that inhabited North and Central America during the late Miocene or late Pliocene up to their extinction at the end of the Pleistocene 10,000 to 11,000 years ago. Mastodons lived in herds and were predominantly forest dwelling animals that fed on a mixed diet obtained by browsing and grazing with a seasonal preference for browsing, similar to living elephants.

M. americanum, the American mastodon, is the youngest and best-known species of the genus. They disappeared from North America as part of a mass extinction of most of the Pleistocene megafauna, widely presumed to have been related to overexploitation by Clovis hunters, and possibly also to climate change.

Modern reconstructions based on partial and skeletal remains reveal that mastodons were very similar in appearance to elephants and, to a lesser degree, mammoths, though not closely related to either one. Compared to mammoths, mastodons had shorter legs, a longer body and were more heavily muscled, a build similar to that of the current Asian elephants. The average body size of the species M. americanum was around 2.3 m (7 ft 7 in) in height at the shoulders, corresponding to a large female or a small male, but large males could grow up to 2.8 m (9 ft 2 in) in height and weigh as much as 4.5 tonnes (5 short tons). However, the 35-year-old specimen AMNH 9950 grew to 2.89 metres (9.5 ft) tall and weighed 7.8 tonnes (7.7 long tons; 8.6 short tons), and another male grew 3.25 metres (10.7 ft) tall and weighed 11 tonnes (11 long tons; 12 short tons). Another species, M. borsoni, is known from 30–40-year-old males that were 3.9–4.1 metres (12.8–13.5 ft) tall and 14–16 tonnes (14–16 long tons; 15–18 short tons) in weight. Like modern elephants, the females were smaller than the males. They had a low and long skull with long curved tusks, with those of the males being more massive and more strongly curved. Mastodons had cusp-shaped teeth, very different from mammoth and elephant teeth (which have a series of enamel plates), well-suited for chewing leaves and branches of trees and shrubs.


At the present time it is ILLEGAL to sell and ship ANY Mammoth Ivory in ANY form to New Jersey & New York.   Both states ban the sale, trade, barter and purchase of all ivory, including fossil ivory. The legislation also bans the sale of Rhino Horns.  Effective July 1st, 2016 it is also illegal to sell and ship ANY Mammoth Ivory in ANY form to California.   While Indiana9 Fossils fully understands and supports the attempts to protect MODERN elephants by enacting these laws, it is preposterous that they have banned the sale of Mammoth Ivory!  There are rock solid ways to determine modern ivory versus fossil ivory which would allow law enforcement to differentiate between the 2, but it is presumed that they opted to throw the baby out with the bath water to save themselves the trouble of having to look at the ivory to make that determination.  If you do not agree with the bans please contact your local politicians and let your voice be heard.  We will update this information with changes to the present laws or if additional states enact similar laws.
