1. Caves and Rock Shelters: Natural caves and rock shelters provided ready-made shelter for early humans. These places offered protection from rain, wind, and predators, and could accommodate multiple individuals or groups.
2. Animal Skins and Hides: Animal skins and hides were used to create tents, coverings, and wraps for warmth and protection from the elements. These materials were sourced from hunted animals and provided insulation against cold temperatures.
3. Branch and Leaf Huts: Humans constructed simple huts using branches, leaves, and other plant materials. These huts were often semi-permanent and provided shelter during hunting and gathering expeditions.
4. Bark and Wood Structures: Bark from trees and pieces of wood were used to create shelters, similar to huts, but with different materials. These structures were constructed in various forms, depending on the availability of resources in the environment.
5. Stone Structures: In some areas, humans built simple stone structures for shelter. These shelters were often circular or oval in shape and constructed with dry-stone masonry techniques, without the use of mortar.
6. Underground Shelters and Dwellings: In certain regions, humans dug pits and created underground shelters. These shelters provided insulation from extreme temperatures and protection from harsh weather conditions.
7. Temporary Shelters: During hunting and gathering trips, early humans might construct temporary shelters using available resources, such as lean-tos made from branches and leaves, or rock overhangs.
It's important to note that the specific types of shelters used during the Paleolithic age varied depending on the geographic location, climate, and available materials. As humans spread across different regions and environments, they adapted their shelter-building techniques to suit the local conditions.
