Other uses include the production of paper, clothing, bedding, mosquito nets and dance masks as well as plastering walls. Bark beaters were made of limestone, wood, ground stone, and even sea shells and their size and shape vary depending on their use. Some bark beaters had long handles and others had an encircling groove around the sides so that they would fit in one hand. This simple, multi-use utilitarian tool was not exclusively invented or used by the Maya since many civilizations and people around the globe and over time have used similar tools. Bark beaters were however important to the Maya for daily use and in present times are important for archaeologists to better understand the great Maya civilization.
