The Island 35 Mastodon was discovered on Island No. 35 of the Mississippi River in Tipton County, Tennessee, United States. In 1900, a Pleistocene mastodon skeleton was excavated approximately east of Reverie, Tennessee and southeast of Wilson, Arkansas. In 1957 the site was reported as destroyed. Mastodons are members of the prehistoric, extinct genus ''Mammut''. They resemble modern elephants. Native to North America, they are said to have lived on the North American continent from almost 4 million years ago, in the Pliocene Epoch, until their eventual disappearance about 10,000 years ago. ==Discovery== In 1900, archaeologist James K. Hampson documented the discovery of skeletal remains of a mastodon on Island No. 35 of the Mississippi River, Tipton County, Tennessee. The site of the prehistoric find is approximately east of Reverie, Tennessee and south of Blytheville, Arkansas.〔 During heavy rain in June 1900, sand at the point bar of Island No. 35 had been washed away, exposing the mastodon skeleton in the sediment when the water retreated from the sandbar in July of the same year. John Pendleton, a resident of Island No. 35, notified his neighbor James K. Hampson about unusual bones he had found exposed by the retreating water at the head of the river island. Reportedly, Hampson visited the site of the find "2 or 3 weeks" after the prehistoric bones had been discovered. By the time of Hampson's arrival, many of the bones had been stolen and the skeleton had been considerably damaged by "curiosity seekers" and "ivory hunters". The remainder of the skeleton ("mainly parts of the hind leg and pelvis") were excavated by Hampson with the help of a pick to separate the mastodon bones from the gravel and pebbles in which they had been resting "cemented together by a clay".〔 Although this find was initially believed to be the remains of a single animal, Morse and Morse subsequently reported that the site consisted of at least two separate mastodons. Several human artifacts were recovered in possible association with the skeletal remains.〔 However, these materials lack direct provenance, and it is generally believed that the artifacts and skeletal remains do not represent Paleoindian/Paleoelephant interaction.〔〔Corgan, James X. and Emanuel Breitburg (1996): "Tennessee’s Prehistoric Vertebrates."
