And what do you think the scutes of titanosaurs and the dorsal structures of
diplodocids developed from?

How about scutes? Why assume they evolved scutes>feathers>scutes, when all you need is scutes>scutes. I don't pretend to know anything scale/scute homology, but I see nothing so far that makes sauropod spines any more "feathers" than iguana spines, or croc scutes.

We need a clarification.
