I thought paleos got their calcium primarily from plant foods, in which
it tends to be abundant. If you have plenty of vitamin D then it is
easily absorbed. Many paleos with strong bones, such as homo erectus and
neanderthal, aren't thought to have eaten fish or many small animals.
Evidence of the abundance of calcium in plant foods is the huge rack of
antlers that males of the deer family generate anew every year. For
strong bones you need lots of animal protein, lots of exercise, and if
you live mostly indoors, and/or clothed, and/or at high latitudes, then
you also probably need dietary vitamin D, such as cod liver oil.
