Some Native Americans used pictographs or Petroglyphs that were paintings or carvings upon cliffs, boulders, or flat rock surfaces made with red orche. There is no infallible way to find out what date the Pictographs or Petroglyphs were made.
Mayan Native Americans had over 800 or more types of shapes or glyphs that could represent almost anything in the Mayan language or culture.
There are 14 letters in the Cheyenne Language. Every tribe has a different language and glyphs or pictures that make them very unique.
