Chapter 26, Problem 5TY
Summary Introduction
Introduction: The climate during the Silurian period was relatively stable. This period marked a major colonization of land by terrestrial plants and animals. Certain species evolved adaptations that prevented them from drying out. In the Devonian period, dry conditions occurred across the northern landmasses. The number of terrestrial species increased during the Devonian period. Vegetation consisted of small plants, ferns, horsetails and seed plants. The first trees and forests were formed by the end of this period.
