The aard vark outrivals, with his great claws, the most skilled burrowing tools of man.
As mentioned on p. 162, the aard Vark is diphyodont like normal mammals.
Another good example of a ground-dweller is the aard vark of Southern Africa.
To that containing the aard Vark, the name Tubulidentata may be applied.
The teeth of the aard Varks are compound, and differ completely from those of all other mammals (see p. 425).
