Actually, most of the big Mesozoic crocodyliforms were not crocodylians at
all.  Crocodylia is strictly defined as the last common ancestor of living
gavials, alligators, and crocodiles, and all of its descendents.  Nearly
all Mesozoic crocodyliforms fall outside this group, and would be
non-crocodylian crocodyliforms.  This includes Sarcosuchus, which was
likely the largest of all time.

Within the crown-group, there's Deinosuchus and, in the Tertiary,
Rhamphosuchus (a really big gavialoid) and Purussaurus (a giant caiman),
all of which were *probably* in the 30 to 40 foot range.

>Deinosuchus is known from freshwater deposits

Estuarine in western Texas.
