Pterosaurs (wing
reptiles) were close
relatives of the
dinosaurs and existed
over the Mesozoic era,
which covers the
Triassic, Jurassic and
Cretaceous periods, i.e.
between 245 and 65
million years ago.
Presumably they suffered
the same fate as the
dinosaurs, with the
arrival of a major
climatic change. The
earliest discoveries of
fossil remains date back
to 1784 but it wasn’t
until the 19th century
that the reptilian nature
of the creature was
established. The skeletal
structure showed that the
4th finger was very
elongated and supported a
wing, and as a result
they were called
Pterodactylus
(wingfinger). Further
study has confi rmed that
they were remarkable
reptiles with large
brains and very effective
lungs and circulatory
systems, making them
highly specialised flying
creatures. They were able
to flap and soar in the
turbulent skies of
ancient times and would
have been quite a
terrifying sight. Many
varieties have been
found, with sizes
ranging from the wingspan
of a sparrow to
Quetzalcoatlus at 50’
(15.2m). Their skulls and
teeth evolved to
specialise on the type of
food that was available,
ranging from fi sh to
carrion. Many of them had
projections from the
skull that may have
functioned as an
aerodynamic balance for
the head, or for
steering, or possibly
making noise.Apparently
winged reptiles were very
efficient flyers, a
characteristic that seems
to have been transferred
to the model.
