The Paleozoic spanned from roughly 542 to 251 million years ago. During the late Paleozoic, great forests of primitive plants thrived on land forming the great coal beds of Europe and eastern North America. By the end of the era, the first large, sophisticated reptiles and the first modern plants (conifers) had developed. The Paleozoic Era ended with the largest mass extinction in Earth's history, the Permian-Triassic Extinction Event.

A connection should:
- Not be "self evident"
- Link at least 3 different sites
- Not duplicate or merely subdivide the "Category" assignment already identified on this site.
- Add some knowledge or insight (whether significant or trivial!) about WHS for the users of this site
- Be explained, with reference to a source
