The body may have been wrapped in a shroud, and was then placed inside a wooden coffin, which was entombed in a rectangular pit surrounded with burial offerings in pottery vessels. The man was buried wearing a long necklace of 340 graduated steatite beads and three separate pendant beads made of natural stone and three gold beads. A single copper bead was also found at his waist.
Note that the entire book describing these discoveries, Harappa Excavations 1986-1990: A Multidisciplinary Approach edited by Richard H. Meadow is available with each chapter a single PDF download. These are basically the most comprehensive, scientific publications about a single ancient Indus excavation site yet.
