    The "late stone age turns out to be at 1821-1835. If we adopt the
    attitude that the San people of South Africa were at the time living in
    the stone age. But it's an intriguing story.

    "A possible later stone age painting of a dicynodont (Synapsida) from
    the South African Karoo"

    Abstract

    The Horned Serpent panel at La Belle France (Free State Province, South Africa) was painted by the San at least two hundred years ago. It
    pictures, among many other elements, a tusked animal with a head that resembles that of a dicynodont, the fossils of which are abundant and conspicuous in the Karoo Basin. This picture also seemingly relates to a
    local San myth about large animals that once roamed southern Africa and
    are now extinct. This suggests the existence of a San geomyth about dicynodonts. Here, the La Belle France site has been visited, the
    existence of the painted tusked animal is confirmed, and the presence of tetrapod fossils in its immediate vicinity is supported. Altogether,
    they suggest a case of indigenous palaeontology. The painting is dated
    between 1821 and 1835, or older, making it at least ten years older than
    the formal scientific description of the first dicynodont, Dicynodon lacerticeps, in 1845. The painting of a dicynodont by the San would also suggest that they integrated (at least some) fossils into their belief
    system.

    So do we know what dicynodonts looked like? What we often 'see' might
    be something like modified 'scales' or 'hair' or 'whiskers'.

    Some had hair? All had hair? None had hair? What we would know of as
    'hair' only came into existence in the Triassic? Are there any
    non-extinct amphibians that have scales that might be similar to 'hair' in
    some ways?

    We have a very good idea of what they looked like. See the entry in Wikipedia. On the subject of paleontology Wiki is generally very good,
    and very up-to-date. The entry even describes the San paintings. They
    were therapsids (like us), but are a stem group, meaning all their
    descendants died out. They probably were endothermic and had hair.

    No living amphibian has scales, hair-like or not.

    But you should know that caecilians do have scales, though they're more
    like fish scales than reptile scales.

    I should have known that, but I didn't.
