From death to brittleness?
Two bodies, on a bed, in an embrace. Windows and doors closed, so little to no air and light, but not completely air/light tight. No scavenger animals/rodents, but bugs would obviously be present. Humid (tropical rain-forest) environment.
The aim is to have my characters stumble across this old castle, and find the bones of two people on the bed. I don't care if the bones are touched they would fall to dust, or if they are moved slightly/disturbed by bugs, or even if some of the bones are dust already, as long as it can be made out that its two skeletons embraced together. (and if not clearly embraced, its at least clear that its two skeletons)
(i know "dust" isn't the appropriate term here, but you get what I mean?)
How many years could this take? Thankyou
EDIT: Just wanted to re-iterate, I don't so much care about the decomposing bodily fluids and flesh. I know that will decompose and be eaten by bugs and will stain the sheets upon decomposition.
I know that mummification is out, as of the humidity.
I'm wanting to know what happens to the BONES well after the process of rotting flesh is done. I know the joints wont stay together, and I know that the bugs will move the bones around a bit if they are eating the flesh. But say that, after a month or so of the people being dead, their bones would still be on the bed, and it would be obvious that two people were on the bed together, even if not embracing? how long would it take before their bones became so fragile and brittle that they would turn to "dust." or upon discovery of the bones, and disturbing the bones, would they disintegrate to dust upon a rush or air or a touch of hand?
