I'd have to say Suchomimus too. Suchosaurus, while probably a Spinosaurid like the above animal is shown to be, is considered a nomem dubium. Suchosaurus is only known from a few teeth and is probably conspecific with Baryonyx.
In all likelihood, you probably remember correctly what the zoo had displayed in "Suchosaurus." I've seen these exhibits before, and most are pretty slip-shod in their dino accuracy.
