In another instance in 2016, a sinkhole in Florida’s Aucilla River (opens in new tab) was declared an "archaeological gold mine" after an ancient human tool and mastodon bones are found inside. For example, on October 16, 1963, Marshal Erb was using a dragline to excavate a pond and found fossils that came to be known as the Perry Mastodon. Mastodons inhabited North and Central America from the late Miocene up to their extinction at the end of the Pleistocene 10,000 to 11,000 years ago. Sometimes, they are found in unusual places. A mastodon ( masts 'breast' + odos 'tooth') is any proboscidean belonging to the extinct genus Mammut. There have been many mastodon fossil discoveries in the past few hundred years. Not long after, in 1807, Thomas Jefferson personally financed an expedition that was by led William Clark to excavate mastodon and mammoth fossils from the Big Bone Lick site in Kentucky. The first mastodon fossils were found in 1705, according to the Oregon History Project, when a large tooth and bone fragments were found in the Hudson River Valley in New York.

Sculptures by artist Sergio de la Rosa show three elephant relatives, from left to right: the mastodon, the mammoth and the gomphothere. Coupled with the coming out of the Ice Age and fighting off humans, the species just couldn't survive. It is likely that the disease didn't kill off the animals directly, but made them weak. Though death by disease sounds like a cut-and-dry answer, "Extinction is usually not a one-phenomenon event," Rothschild told Live Science. Le mastodonte d'Amrique habitait exclusivement l' Amrique du Nord, et surtout l'est, o il trouvait un habitat. Il possde d'normes dfenses courbes, mais elles ne sont pas aussi courbes que celle du mammouth.

This led the researchers to think that a tuberculosis pandemic contributed to their extinction. Le Mastodonte d'Amrique ( Mammut americanum ), mesure 1 mtre de moins que le mammouth, soit plus de 3 mtres de haut.
They found that 52 percent of the 113 mastodons they studied had signs of tuberculosis. Others, like researchers Bruce Rothschild of the Northeastern Ohio Universities College of Medicine and Richard Laub of the Buffalo Museum of Science in New York, have a different theory. Some scientists think that the Earth warmed up from the Ice Age too quickly for the mastodon to adapt or that humans hunted them to extinction. Most of these theories boil down to climate change and/or human hunting, according to Simon Fraser University. 2014, Elizabeth Kolbert, chapter 2, in The Sixth Extinction: An Unnatural. Mastodons went extinct around 10,000 years ago. mastodon ( plural mastodons ) Extinct elephant -like mammal of the genus Mammut that flourished worldwide from Miocene through Pleistocene times differs from elephants and mammoths in the form of the molar teeth.
They typically inhabited spruce woodlands around valleys and swamps, according to Cochise College. Though mastodons appeared primarily in North and Central America, they eventually spread all over the world, in every continent except for Antarctica and Australia.
