If either croc predators or croc prey are capable of viewing the crocs from
above, selection pressure will produce cryptic coloration pretty darn
quick. We can't assume that, just because modern crocs are not well
"camouflaged" from above, that Cretaceous ones did not possess such
coloration. The more so if dinosaurs did in fact deal with polarized light
better than we mammals do; the crocs would be less able to hide under the
surface dazzle.
