The Tiferes Yisroel in pesachim says that people would bury 
their dead in a temporary grave, and after the meat had rotted, the 
bones would be reinterred in their ancestral cemetery. Can anyone point 
to a source, and perhaps also an explanation for this practice? 

Perhaps it could be inferred from Yechezkel 39:15 which states: "V'gam
ha'ovrim ba'aretz v'ra'a etzem odom u'vo-no etzlo Tziyun ad kovru oso
ham'kabrim el gai hamon gog."  
(Just a wild guess).
