Gladocephaloideus
was a very exciting discovery as it was the first gallodactylid
pterosaur
to be discovered in Asia. As such Gladocephaloideus
is
thought to be related to Cycnorhamphus
which itself is known from
Germany.
The
jaws of Gladocephaloideus are filled with numerous
small and thin teeth
which were probably used to filter invertebrates from water and silt.
Also of interest is the presence of what seems to be ‘hairs’ on
the body of Gladocephaloideus which seem to have
been there for
insulation. These ‘hairs’ would in actual fact be what are called
pycnofibres, growths that are actually more like primitive feathers
in form that are also found upon other pterosaurs, most famously on
the pterosaur Sordes.
This strongly suggests that pterosaurs evolved
into reptilian creatures that did not have cold-blooded metabolisms
like reptiles we know today.
