Spinosuchus was probably similar in size to Trilophosaurus, although as you can see its tall neural spines give its back a raised hump/sail and less of the lean, iguana-like silhouette.

For the coloration, I looked at a bunch of arboreal reptile species, large and small. It's harder than I thought to give it the loose, splotchy look of reptile coloration without losing the semblance of an actual pattern.

Sometimes you just gotta ask yourself...if I don't make a super spiny Trilophosaurus, who will?
