The Searunner by Smnt2000 The Searunner by Smnt2000

As you can see, I'm plenty of free time lately. So, since I drew a lot of theropods, I decided to do something different. A pterosaur. Yeah, I've already drawn the mighty Quetzalcoatlus but there was a critter to interesting for leaving undone. It shares the most incredible crest along with the incredible Tupandactylus and the weird Nyctosaurus. It is...

Thalassodromeus sethi, the "Seth's searunner". This is crazy. The head is simply huge. Not as huge as in Tupandactylus, but it's very close. And we don't know very well the rest of its body so I restored it after Tupuxuara. Among the several options, beak and crest are shown fused together as in hornbills. I think it fits well, but is a very delicate subject. About the crest, it isn't similar to the one commonly depicted. Why? Because in the original specimen you can clearly see that the skull is damaged. The general shape is altered a bit and some parts are broken and/or erosed. The original head must have been different. Also, the wings. The attachment is near the knee, while the wing itself resembles the bats' ones. In the last months I was deeply interested in pterosaurs, so I've made a few researches. The wings in Pterosauria surely were different among the several species, but this is presumibly the most common type. I didn't add on pycnofibres because they're present only on the wings of smaller species, such as Jeholopterus and Pterorhynchus. In bigger species, the question is much more questionable. Also, the cruropatagium/uopatagium is reduced. Species that spended a lot of their time on land (in this case, Azhdarchoids) didin't need a lot such a feature. And it's not digitigrade. It's just this pose.

So this is it. Enjoy it!

Thalassodromeus was a large pterodactyloid pterosaur found in northeastern Brazil. Thalassodromeus was believed by Kellner to have fed in a similar way to modern skimmers; trailing its lower jaw in the water while it flew. However, later research on its jaw and neck anatomy suggested that for this and other larger pterosaurs it would not be feasible to skim because of the drag: the energy expenditure would be too high. Kellner assigned Thalassodromeus to the Tapejaridae. Other analyses however, showed that it was, joined with Tupuxuara in a Thalassodrominae, more closely related to the Azhdarchidae.

Ps: sorry for the colours' quality. Bad scanner

The double-misnamed top land predator of Albian South America.

It is a terrestrial hunter rather than oceangoing and they named it after the wrong Egyptian god.

I'm not entirely sure I the wing membrane should spread from arm to leg , but other than that this is perfect!

The evidence against the animal skimming is pretty strong. Aside from Rhynchops, the only animals that skim can only do it for a very, very short period of time, such as a gull snatching fish from the surface, because the energy required is so difficult to maintain. Kellner still champions the idea, there's some data to support it, but for the most part it is difficult to address without better mechanical data. In general, though, Thalassodromeus sethi lacks a few key features that would suggest it could keep skimming enough to prefer to feed in this way.

Note: Minor nitpick. The pes should be plantigrade.

Did it really sound like that in the description? Geez, never wanted to say such a thing. I was only refering to the literal translation of the genus, which is "searunner".


"Note: Minor nitpick. The pes should be plantigrade."

I choosed to depict the pterosaur walking/trotting, so it seems like it's digigrade but trust me, it's not. Still, I know I've done an awful job with the locomotion of the animal. I'm sure as hell I'll re-do it in the future, so I'll keep that in mind.

You did make a reference to the skimmer, so I wanted to be clear on that lest people get the notion it would skim.

We don't have any complete skeleton of this pterosaur, but the skull alone is around 1.40 metre long, with an estimated wingspan of 4-5 metres.

This is great! I remember when Paleoartists used to depict Pterosaurs looking like birds a lot. This is totally different and great.

Thank you :) ! The only thing I depict after birds is the beak. Cassowaries, ostriches and primitive birds are excellent examples to see how the beaks of pterosaurs (and some dinosaurs too) might have looked like. Other than that, aside from colours, I don't use pterosaurs as a good analogues for pterosaurs.
Still, thanks!

Oh my English is bad! ;) I tried to say I like your picture a lot, because you managed to give the animal a totally unique look. It does not look like a bird at all, which is cool. (some years ago other paleoartists often depicted Pterosaurs looking like seabirds a lot, I found this kind of too simple...) Great artwork of yours!

Very nice! A word of caution, though; anything produced by David Peters regarding his take on fossil species (pterosaurs in particular) is to be taken with a pound of salt, considering his research techniques are questionable at best.

Yeah, I know. But I didn't have any kind of skeletal for Tupuxuara and/or Thalassodromeus. I didn't want to use the Peters' one but after searching for too much on the net I had to. I've been very carefull with the body and I modified it a bit. The head is after Mike Hanson and Mark Witton, so for that it was never a problem.
By the way, thanks ;)

Jeholopterus has this very fluffy tail, and I like to imagine all short-tailed pterosaurs to have such a feature.

I'll have to keep that in mind for the future.

It's not something you see in pterosaur illustrations very often. It has the effect of making them both odder and cuter at the same time.
