There were few clues on Zarqawi's extreme ideology or the militant groups he was linked to in the rubble of the building that was pulverised by two 227kg bombs in a US air strike on Wednesday.
One leaflet identified a radio station in Latifiya south of the capital as an apparent target.
A few feet away was a magazine picture of former US president Franklin D Roosevelt.
Also beside the slabs of concrete was a woman's leopard skin nightgown and other skimpy women's clothes.
The US military had said the air strike killed a total of six people, three males and three females.
It said on Friday that a wounded Zarqawi was still alive when US troops reached the site but died shortly afterwards.
Looking over the site where Iraq's most wanted man may have been plotting more suicide bombs, an Iraqi soldier said he felt a great sense of relief.
