Mastodon (Ultraverse Comics)
A mastodon ( 'breast' + 'tooth') is any proboscidean belonging to the extinct genus ''Mammut''. 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. Mastodons are the most recent members of the family Mammutidae, which diverged from the ancestors of elephants over 20 million years ago. ''M. americanum'', the American mastodon, and ''M. pacificus'', the Pacific mastodon, are the youngest and best-known species of the genus. They lived in herds and were predominantly forest-dwelling animals. ''M. americanum'' is inferred to have had a browsing diet with a preference for woody material, distinct from that of the contemporary Columbian mammoth. Mastodons became extinct as part of the Quaternary extinction event that exterminated most Pleistocene megafauna present in the Americas, believed to have been caused by a combination of climate changes at the end of the Pleistocene and hu ...

Pleistocene Megafauna
Pleistocene megafauna is the set of large animals that lived on Earth during the Pleistocene epoch. Pleistocene megafauna became extinct during the Quaternary extinction event resulting in substantial changes to ecosystems globally. The role of humans in causing Pleistocene megafaunal extinctions is controversial. Megafauna are any animals with an adult body weight of over . Pleistocene megafauna include the straight-tusked elephant, cave bear (''Ursus spelaeus''), interglacial rhinoceros (''Stephanorhinus''), heavy-bodied Asian antelope ('' Spirocerus''), Eurasian hippopotamuses, woolly rhinoceros, mammoths, giant deer, sabre-toothed cat (''Homotherium''), cave lion, and the leopard in Europe. Paleoecology The last glacial period, commonly referred to as the 'Ice Age', spanned 125,000 to 14,500 years ago and was the most recent glacial period within the current ice age which occurred during the final years of the Pleistocene epoch.

Slavery In The United States
The legal institution of human chattel slavery, comprising the enslavement primarily of Africans and African Americans, was prevalent in the United States of America from its founding in 1776 until 1865, predominantly in the South. Slavery was established throughout European colonization in the Americas. From 1526, during early colonial days, it was practiced in what became Britain's colonies, including the Thirteen Colonies that formed the United States. Under the law, an enslaved person was treated as property that could be bought, sold, or given away. Slavery lasted in about half of U.S. states until abolition. In the decades after the end of Reconstruction, many of slavery's economic and social functions were continued through segregation, sharecropping, and convict leasing. By the time of the American Revolution (1775–1783), the status of enslaved people had been institutionalized as a racial caste associated with African ancestry. During and immediately ...

Big Bone Lick State Park
Big Bone Lick State Park is located at Big Bone in Boone County, Kentucky. The name of the park comes from the Pleistocene megafauna fossils found there. Mammoths are believed to have been drawn to this location by a salt lick deposited around the sulfur springs. Other animals including forms of bison, caribou, deer, elk, horse, mastodon, moose, musk ox, peccary, ground sloths, wolves, black bears, stag moose, saber-toothed cats, and possibly tapir also grazed the vegetation and salty earth around the springs that the animals relied on for their diet. One mastodon bone was unearthed here with a noticeable cut mark on it, implying that the Clovis people lived in the area thousands of years ago. The area near the springs was very soft and marshy causing many animals to become stuck with no way to escape. It bills itself as "the birthplace of American paleontology", a term which dates from the 1807 expedition by William Clark undertaken at the direction of President Thomas J ...
