paleonet Disaggregating coprolites

[Mike Everhart <mike@xxxxxxxxxxxxxxxxxx>]

All,
The Smoky Hill Chalk produces a large number of comprolites, some of 
which contain fish bones, and other remains:

Most are considered to have originated from sharks, although Williston 
and others mentioned finding coprolites that they believed were from 
mosasaurs.

I think most are composed primarily of calcium apatite which does not 
appear to react with acetic acid. .
  
Given that most of the remains potentially inside these coprolites are 
in rather fragile condition, mechanical methods are a bit risky. Is 
there another, safer method of disaggregating them?
