Dung, Part Two Still other nutrients came from dung—dung the mammoth ate. Animal droppings may have supplemented his daily intake of grasses and other vegetation (here, a moss spore structure). The team recovered fruit bodies of a dung-inhabiting fungus that only develops at least a week after manure is exposed to air, which the mammoth's own poop never was. The swallowed stool was probably mammoth dung, in fact. Among living mammals, elephants (along with hyraxes and manatees) are unique in having no bile acids—and none were found in the feces of the mammoth, a close relative of the elephant.
