The problem that I've found with trying to describe the behaviours of
_Suchomimus tenerensis_ is that, while it was certainly big enough to tackle
large deinosaurs, it's jaws were slim as hell. About as slim as _Tomistoma
schlegelii_. How could this huge theropod take down another large deinosaur
with jaws that slim? 

If it tried it's jaws would snap under the stress. And if it used other body
parts to kill it's prey, then why evolve the long jaws in the first place.

The only thing that seems to make sense is the fishing existence.

So the next logical question to ask is how an piscivorous, supposedly
semi-aquatic animal grow to be so frickin big?

That I don't have an answer for.

All the large semi-aquatic animals today are either herbivores, or eat
terrestrial animals.

Well, all but one, _Gavialis gangeticus_.

So maybe if we can find out how a piscivore like _G.gangeticus_ can grow to 7
meters, then we can find out how an (assumed) piscivore like _S.tenerensis_
can grow to 9 meters.

Any other thoughts?
