That would be my first hypothosis followed by being something similar to a modern anole's dewlap. Subject: Re: And you though I was weird...

But it is always nice to take a look at dinos... Subject: Re: And you though I was weird...

From: Sordes posted Wed, Oct 14 2009, 1:45pm  The dorsal spines of Dimetrodon and Spinosaurus were completely different in nearly every aspect, the only common trait is that both are very long. You should also keep in mind that the thermoregulation function is only a theory, a wide-spread theory, but was never proven. In the case of Spinosaurus it is very dubious that it hat a "sail" at all, because it is much more probable that the dorsal spines anchored muscles and sinews and were not only covered by skin.
