The only way theory this could be corroborated if we are fortunate enough
(VERY fortunate) to find a spinosaur specimen with integumentary structures.
If spinosaurs were not content just to eat the outer muscle layers, and
delved into the innards of carcasses as well, then you'd expect the
spinosaur head to be naked - like modern vultures (vulturids/cathartids and
accipitrids) and the marabou stork.
(I ain't holding my breath for that discovery though.)

"Facultative" might be okay; but I have trouble imagining a multi-ton
*obligate* terrestrial fisheater.
