To
realise the full meaning of the name Ludodactylus
(toy finger),
you may have to revisit your childhood. Whereas Pteranodon
is by far
the most easily recognised pterosaur by the general public, toys of
it often have the presence of teeth in its jaws in order to make it
look more ferocious. This is what you may call a deliberate error on
the part of toy makers, especially when you realise that the name
Pteranodon actually means 'Toothless beak'.
Well the toy makers
were actually ahead of their time because out of Brazil comes
Ludodactylus, and not only does Ludodactylus
sport a similar crest to
Pteranodon but it also has teeth. Anyone who
wanted an excuse to
claim their old 'toothed Pteranodon' toys as
scale replicas can now
do so, just remember to call them Ludodactylus.
Although
the crest is similar to Pteranodon, Ludodactylus
actually belongs to
the ornithocheirid group of pterosaurs, although it lacks any snout
crests like others of its kind. Ludodactylus
would have likely been a
piscivore like other members of the group, relying upon its sharp
teeth to seize fish in the water. The teeth are considerably larger
towards the end of the jaws, reducing in size to actually be quite
small towards the rear of the mouth. This may also indicate a skim
fishing lifestyle where the tips of the jaws were dipped below the
surface of the water while Ludodactylus was in
flight.
Ludodactylus
has been considered to be the same pterosaur as Brasileodactylus,
and
if correct then Ludodactylus would become a synonym
of
Brasileodactylus. However this is so far not a
certainty and the
discovery of new fossil material may confirm Ludodactylus
as either a
synonym or a genus in its own right.
