have been difficult for the creature to reach down far enough to
grab a fish? Especially if the vertebral sail restricted movement in
any way. It would seem that the long jaws, and less recurved neck,
were adapted for reaching down (I believe the same has been said of
Dilophosaurus - straighter neck, kinked snout = small game hunter).
It would seem that anything a spinosaur could reach with its forelimbs
would have been in an inconvenient position for it to then bring the jaws into
play. Besides, the claw of Baryonyx seems much to heavy to be
an efficient fishing tool. Modern fish gaffs (spelling?) are usually
sharp narrow tools. Plus, from my observations, it seems that
the robust hands of Suchomimus may not have had much in the may of
manoeuvrability - perhaps more of a robust club than a precise tool.
