The Paleolithic or Palaeolithic (c. 3.3 million – c. 11,700 years ago) (/ ˌ p eɪ l i oʊ ˈ l ɪ θ ɪ k, ˌ p æ l i-/ PAY-lee-oh-LITH-ik, PAL-ee-), also called the Old Stone Age (from Ancient Greek παλαιός (palaiós) 'old' and λίθος (líthos) 'stone'), is a period in human prehistory that is distinguished by the original development of stone tools, and which represents almost ...
The term Paleo-Indians applies specifically to the lithic period in the Western Hemisphere and is distinct from the term Paleolithic. [note 1] Traditional theories suggest that big-animal hunters crossed the Bering Strait from North Asia into the Americas over a land bridge . This bridge existed from 45,000 to 12,000 BCE (47,000–14,000 BP). [1]

The span of recorded history is roughly five thousand years, beginning with the earliest linguistic records in the third millennium BC in Mesopotamia and Egypt .
All known life during the Cambrian was aquatic so areas of the United States above sea level would have been sterile wastelands. [8] Trilobites are the most common kind of animal in the Cambrian fossil record. [9] Especially notable are the Elrathia of the Antelope Springs region of Utah. [10] Sponge-like archaeocyathids were common in Nevada. [9]
The Paleolithic cave art was first discovered in 1868 and depicts bison, deer, and other animals. Scientists have dated the paintings to be between 13,000 to 14,000 years old.
The era typically associated with the archetype is the Paleolithic Era, sometimes referred to as the Stone Age, though the Paleolithic is but one part of the Stone Age. This era extends from more than 2 million years into the past until between 40,000 and 5,000 years before the present (i.e., from around 2,000 kya to between 40 and 5 kya).
However, new research suggests that our ancestors from the Paleolithic era probably would have eaten a more. Skip to main content. Sign in. Mail. 24/7 Help ... 800-290-4726 more ways to reach us.
