Carboniferous period

Imagine swamp. Saturate the air and fumes of rotting leaves. Strange sounds of various insects crawling on the forest floor . Water gurgling noise and crowns of the giant trees stretching far to the top, into the fog that enveloped the world of endless forests and swamps . This world existed about 320 ml. years ago in the Carboniferous period . This is the only time in the history of the Earth when the world is ruled by the plant. And animals were making their first tentative steps . Here's an example cochleosaurus bohemicus - ancient amphibian shown in this figure , sitting on a fallen tree trunk . Wall left standing trunks of giant Lepidodendron, and on the right the ancient ferns and Neuropteris sp Sigillaria in the background.
