In 2012, a study about a specimen of Dimetrodon giganhomogenes suggested, among other interesting conclusions, that the animal didn't had a complete sail, but that the tip of its spines lacked the so characteristic membrane. This was because the tips of some spines were very twisted (due fractures that healed after some time), and they wouldn't deform in such way if there was a membrane sustaining them.

In this illustration, I depicted some twisted spines, but still a complete sail. The explanation for this is the case of the same incident that fractured the spines have also ripped off the membrane around them, precluding the skin to sustain the injured bones (thus allowing the deformation).

With an injury like that, it's built in radiator won' be as efficient as it used to.

Looks like he's been in a fight or two.

I doubt it would sustain such an injury in the Permian.

Would it be able to sustain the injury only in the Triassic? - just kidding xP
Actually, we in fact know that the animal survived the wounds because the bones have signs of healing.

Quite resilient and in the Triassic it'd be just as bad.

Now this looks more better and reasonable...Vitor my pal you got the depiction right to the brink. This looks a loads better than the way people we're depicting it originally....I really think those paleontologists could've explained the detail of the membrane in the Dimet's sail instead making it seem that the sail was actually just a large hump with long spines coming out of it like a lightning rod.

Thank you ! I'm also very skeptical for the "new look",  this explanation is more reasonable to me, too.

Fascinating! An interesting take on those deformed spines. Kind of reminds me of Bettas, in a way- giant display structures that are constantly in tatters. I should really do more Pelycosaur art, explore all the possibilities of the sail extent.

Many thanks! ^^

I wonder how it would sustain such an injury
Awesome pic by the way :)

Awesome! :D
One of the coolest Dimetrodons, I've seen so far!

Thank you so much! :thanks:

Thank you, this comes in quite handy.

I was JUST about to colour a Dimetrodon based on the "half-sail" look. Guess now I can correct the sail to the classic look again.

No problem, but the half sail is still a possibility, if you consider it plausible. I prefer the ripped membrane theory of this illustration, but it is personal view.

Interesting interpretation. Is there more evidence for this than the alternate idea? 
Vitor-Silva's avatar
Vitor-SilvaProfessional
Thanks! Well, the only evidences we have are the fractured spines themselves. Both ideas justify how the injured spines could bend so much, but I, personally, still am not convinced with the half sail appearance.
