All of the burrowing animals, the geofodes, enter a very different world, which exists only a very short spacial distance from the actual desert environment itself.
—Raymond B. Cowles, Desert Journal: Reflections of a Naturalist (1977), p. 105
Geofodes appears to be a coinage by Cowles, deriving from geo and the Latin fodere that gives us fossorial. Or perhaps it’s a slip, because his book went to press posthumously. At any rate, it ain’t in my dictionary.
