Rauisuchid Osteoderms?

[Papi-Anon]

I'm working on a postosuchus figure and was curious what sort of plates and fringes rauisuchids might have had on their dorsal regions (if any).

While my figure of ol' posto is based on the more modern bipedal posture I'm unsure if the back armor of modern crocodylians is the way to go in terms of 'accuracy'. I know some rauisuchids have been found with osteoderms but I've seen a variety of illustrations ranging from full-blown modern croc back scales to subtle plate-bands with no fringes or stout spines. I'll admit that the now inaccurate WWD postosuchus's back-plates are kinda the default that comes to mind for me, but what exactly were the more common forms with rauisuhids' osteoderms we've found so far?

@Papi-Anon Prestosuchus has a double row of osteoderms on its back and a single row on its tail, in case that helps.

It does. Ultimately I gave my Postosuchus model crocodilian-like scale and osteoderm patterns due to their close relation as pseudosuchian groups. I was tempted to copy the WWD Posto's osteoderms, though.
