Devonian [deˈvəʊnjən] (1 gen 354680381 anni a. C. – 1 gen 29800000 anni a. C.)

Descrizione:

First trees and spread of forests. First 4-legs animals. First ferns and club-mosses. Modern fish evolve.
The Devonian Period is sometimes called the “Age of Fishes” because of the diverse, abundant, and, in some cases, bizarre types of these creatures that swam
Devonian seas. Forests and the coiled shell-bearing marine organisms known as ammonites first appeared early in the Devonian.
