When the Mesozoic got ugly – naked, hairless, (and featherless) pterosaurs
DAVID UNWIN  & DAVID MARTILL

With key roles in flight, thermoregulation and protection of the body, the
integument was of fundamental importance to pterosaurs. Determination of
the basic anatomy of this structure could provide a range of new insights
into the palaeobiology of these enigmatic volant reptiles. Presently,
however, there are several conflicting hypotheses regarding the
construction of the integument, all founded on limited numbers of
specimens, and not one of which is fully consistent with the available
fossil evidence. We have developed a new model based on investigations of
more than 100 specimens all of which show some form of exceptional
preservation. This data set spans the entire temporal and systematic ranges
of pterosaurs and a wide variety of preservational modes. The model has
three principal components: (1) A thin epidermal layer. The external
surface of the integument was glabrous with a smooth, slightly granular, or
polygonal texture. Attenuate 'bristles' fringed the jaws in two
anurognathids and small tracts of filaments may have adorned the posterior
cranium in some pterosaurs. (2) A layer of reticular and filamentous
collagen and of variable thickness and complexity, formed much of the
dermis. Helically wound bundles of collagen fibres (aktinofibrils), were
present throughout all flight patagia. Variation of aktinofibrils in terms
of their dimensions, packing, orientation and stiffness permitted localized
variation in the mechanical properties and behaviour of the flight patagia
which varied from relatively stiff distally to more extensible and flexible
proximally. 'Feather-like' structures reported in Jeholopterus appear to be
partially unraveled or decayed aktinofibrils. Collagen fibre bundles were
also present in footwebs, and in the integument of the neck and body. These
structures have often been mis-identified as 'hair' (pycnofibres). (3) A
deep dermal layer with muscles fibres, blood vessels and nerves. The
pterosaur integument was profoundly different from that of birds and bats,
further emphasizing the sharp disparity between these volant tetrapods.

[What we need is a baby pterosaur in amber to see if it's fuzzy...]
