Well, I just happen to have already written a song which is, in part, about roo poo and the dung beetles that evolved to harvest it. Here's the relevant verse:

If you're a biophysicist, then you can calculate
That beasts can't move efficiently above a certain weight
By hopping on their hind legs, and the mass this rule allows
Means kangaroos cannot evolve to be the size of cows.
In consequence, the dung they leave is golf-ball sized, or less,
And so Australia's coprophagous fauna could address
Itself to handling the smaller forms of pre-digested leaf,
But not the kind that's left behind by half-ton hunks of beef.

The song also refers to dung-based termite nests, which you might consider to be the result of a process akin to papermaking.

If you want to see the whole song, you can find it here.
