The correct answer is: a) Bone tools.
Mesolithic sites in Punjab have yielded evidence of bone tools. These tools were made from the bones of animals, such as deer, cattle, and sheep. They were used for a variety of purposes, including hunting, butchering, and woodworking.
Bone tools are a type of archaeological artifact that is found in many different parts of the world. They are typically made from the bones of large mammals, such as deer, cattle, and sheep. Bone tools can be used for a variety of purposes, including hunting, butchering, and woodworking.
The earliest evidence of bone tools dates back to the Lower Paleolithic period. However, bone tools became more common during the Mesolithic period. This is because Mesolithic peoples were hunter-gatherers who relied on a variety of tools to survive. Bone tools were an important part of their toolkit, and they were used for a variety of tasks.
Bone tools are typically made from the long bones of animals. The bones are first split lengthwise, and then the desired shape is carved out using stone tools. The tools are then sharpened and polished.
Bone tools can be divided into two main categories: tools for cutting and tools for scraping. Cutting tools are used for tasks such as butchering animals and skinning hides. Scraping tools are used for tasks such as woodworking and hide preparation.
Bone tools are an important source of information about the lives of Mesolithic peoples. They can tell us about the animals that they hunted, the plants that they gathered, and the tools that they used. Bone tools can also tell us about the social and economic organization of Mesolithic societies.
The other options are incorrect because they are not typically found at Mesolithic sites in Punjab. Rock art is typically found at sites from the Paleolithic period, while beads and ornaments are typically found at sites from the Neolithic period.
