No, the behemoth would have been a larger sauropod dinosaur. Mishipishu, or "water panther" in Ojibway language is described in Amerind oral traditions has having a sawblade back, red fur, and a "great spiked tail" which he used as a weapon. That's a stegosaur. Mishipishu glyphs were common when Europeans first got here and Lewis and Clarke described their Indian guides as being in mortal terror of them. They appeared around rivers and lakes and were meant as warnings, i.e. "One of these lives here, be careful". There are only a few of them left now. Amerind artists touch the things up every few decades or so and the horns on the Masinaw glyph were obviously added long after the last stegosaur died out; real stegosaurs didn't have horns.
But given the standard theory we were indoctrinated with in school in which dinosaurs died out tens of millions of years ago, the idea of drawing ANY creature with a sawblade back would never have occurred to anybody.
