The main groups of spider developed about 200 million years ago, in the Triassic period. Spider-like arachnids are known from towards 400 million years ago, and some true Spiders are known from about 300 million years ago in the Carboniferous period.
The spiders are part of the Arthropod family, which dates back to the Cambrian era, 500 - 600 million years ago.
