Scleromochlus taylori by T-PEKC Scleromochlus taylori by T-PEKC
Scleromochlus taylori is small (about 20 cm long) enigmatic archosaur that lived during the late Triassic in what's now Scotland. It's ornithodiran archosaur, probably closely related to Pterosauria. Interesting fact is that what's known from this animal are not actual fossilized bones but rather their impressions preserved in a sandstone.

The filamentous integumentary structures presented in this reconstruction are speculative but not beyond realms of possibility.

Reference: Jaime A. Headden's skeletal drawing of Scleromochlus - [link] [link]

Media: Pencil (2B, 5B) on yellow paper.
Done: 2012.

Dynamic pose!
So, is it safe to assume this guy could be considered the "urvogel" of pterosaurs?

I don't like to think about extinct animals as "urvogels" in respect to their particular group, because for me it's more or less artificial concept, but since most phylogenetic stydies of pterosaurs put Scleromochlus as basal (or basal most) member of the clade, I guess you can call it the pterosaurian "urvogel". At least until new fossils change this view. :)

Fantastic, you did a great job with the integument and the dynamic pose. The detail is also gorgeous.

Nice! I'm biased because of the source material, but...

Just one point: While there is a good possibility basal pre-pterosaur/pre-dinosaurs had some form of "covering" like you show, spiny or vaguely fur like, the little "Hardened Devil" sported a row of osteoderms down the back, and along the belly, plates not dissimilar to crocodilian osteoderms, but very thin. It's likely, then, that Sclero would have been armored, scaly, and not all that fluffy.

Thank you!

See, I didn't know that. Not enough researching on my side. I considered that croc-like osteoderms are probably basal to ornithodirans, but overlooked the osteoderms on the back. That's the main problem with my reconstruction then. Though I think that the filamentous structures could grow from between the scales (as what's the case with feathers growing from between the scale on the feet on some modern birds), so their presence is not that far-fetched considering the distribution of non-scaly integumentary structures among ornithodirans. BTW, I tried to give the whole ventral side of the animal crocodilian like osteoderms, but smaller and more delicate.

Anyway, thank you for pointing out thse obvious inaccuracies! I need to research better sometimes.

I tend to agree with you about the yellow paper. It just make the whole drawing looking more appealing to me. I'm eager to try ink on this paper. I'm sure the result will be very good.

I guess it doesn't. Because of the proportions of its hindlimbs I imagine it as a saltator, as depicted in this drawing.

Me too. Sometimes I wonder how some deviations get DD. I guess it all depends on the people who submit deviations to the admins. Poor list of submitted artworks = poor DD.

Does that mean it is not a true dinosaur, but a related branch?
Reply
:icont-pekc:
T-PEKC Featured By Owner Nov 17, 2012
Yes, it's not a true dinosaur but still related to them, as much as pterosaurs are related to dinosaurs. The clade Ornithodira consists of two main branchs - one leading to pterosaurs (Pterosauria/ or Pterosauromorpha) and the other leading to dinosaurs (Dinosauromorpha). Dinosauria itself (the true dinosaurs) is part of the more inclusive clade Dinosauromorpha which includes animals like silesaurids, Lagosuchus, Marasuchus, etc. The most popular hypothesis is that Scleromochlus is a sister-taxon to Pterosauria.

Have any recent finds clarified the evolution of pterosaur wings?
Reply
:icont-pekc:
T-PEKC Featured By Owner Nov 17, 2012
Honestly, I have no idea. I'm not that much into pterosaurs and follow mainly dinosaur publications. Though while drawing this animal, I thought how wings of pterosaurs evolved in such short time - just few millions of years. If I get more free time I may look for some info on this problem.

Perhaps early pterosaurs all lived in a small area before expanding, and that area had poor fossilisation potential.
Reply
:icont-pekc:
T-PEKC Featured By Owner Nov 17, 2012
Absolutely reasonable assumption, in my opinion. Especially the part about the poor fossilization potential of the area eventually inhabited by these early pterosaurs. The size of the animals, along with the type of sedimentation could also be a major factors preventing fossilization.
