With plates and spikes - the heavily armoured Eusaurosphargis aff. dalsassoi

Besides the wealth of nothosaur and pachypleurosaur fossils from the Vossenveld Formation, there are findings of bones that show very peculiar shapes, not easily attributable to the aforementioned groups. Among these are vertebrae with very long transverse processes, curved dorsal ribs with broadened portions known as uncinate processes, and peculiar shaped dermal armour (generally referred to as osteoderms), usually in the form of small bony cones. For a long time, the identity of these bones remained obscure, but lately, there is increasing evidence that all those materials belong to a single enigmatic diapsid, Eusaurosphargis, known from several European fossil localities.
