In RL, the northern continents are full of molehills, sub-Saharan Africa has the so-called golden moles, and Australia has marsupial moles. Madagascar has at least a digging tenrec. South America has nothing of that sort. Such animals simply never evolved there. This is a source of great puzzlement to those few people who ever think about these matters.

  • In RL, the northern continents are full of molehills, sub-Saharan Africa has the so-called golden moles, and Australia has marsupial moles. Madagascar has at least a digging tenrec. South America has nothing of that sort. Such animals simply never evolved there. This is a source of great puzzlement to those few people who ever think about these matters. Naturally, the situation is different in Spec. The South American continent, especially across the flat Pampas, is peppered with molehills. The first spexplorers theorized that real moles from North America had reached this far south. The truth is not so simple, or perhaps it is simpler: Docodonts (non-mammalian mammaliaforms dating back to the Middle Jurassic) have survived in Spec's South America. This fact is very convenient for RL paleontologists, because so far the only reasonably complete docodont specimen comes from the Late Jurassic of Portugal. Like ancient Haldanodon, today's moliarties use mainly their forehead, which is covered by a thick horny pad, to dig in soft soils. Unlike true moles (which do live in Spec), moliarties sprawl, lay eggs, and, unique among extant mammals, retain the archaic double jaw joint, formed by bones that, in other mammals, support the tissues of the inner ear. Like many archaic mammals, male moliarties bear a poison spur on each ankle.
