@gungasnake,
Quote: No North American creature other than the stegosaur ever had a "great spiked tail"
Stegosaurs were no water dwelling animals. Their bulk almost precuded them access to deeper waters. They would float like a rhino in a river.
All you "evidence" states that the Mishipeshu was a water creature, some even said it was a sturgeon. I can understand your insistnace on a stegosaur, it makes your Creationist claims seem less outrageous. BUT,so far, weve seen nothing other than some cartoons, arts n crafts, and some legends.
ANYWAY, the stegosaur was a lnd dwelling herbivore and its fossils were found in groups (like hadrosaurians) and all were found in a small geologic range (They were gone in the K terminal events). The Great lakes have really good Cenozoic and "anthropocene" deposits, and guess what? NO DINOSAURS AT ALL, Instead , weve got ample fossils of things like elephants, bison, short faced bears, dire wolves, camels, horses and others. ALL MAMMALS and modern fishes turtles etc. NO DINOSAURS, Did I say that THERE WERE NO DINOSAUR FOSSILS?
