Which ancient civilization featured button remnants made from shell dating back to around 2500 BCE?

Answer

Indus Valley Civilization

Archaeological findings reveal that the earliest known iterations of button-like objects appeared in the Indus Valley Civilization around 2500 BCE. These artifacts were often constructed from shell and typically exhibited perforations. However, their primary role was ornamental, functioning as decorative toggles or attachments for jewelry or straps, rather than serving the practical function of fastening garments through buttonholes, which developed much later.
