Superb!

I love the colorful patterns that you have chosen. We can see the influence of Malawisaurus on this reconstruction.


About Malawisaurus, we must remain cautious regarding the reconstruction of the skull of this dinosaur. In fact, we know less than fifty percent of its skull. It lacks many important parts including postorbital, frontal, prefrontal, nasal, lacrimal and nearly all the maxilla. It lacks also bones of the lower jaw (angular and surangular).

Was found mainly, most of the posterior part of the skull (braincase, parietal, quadrate, etc.) and two elements (a premaxilla and a dentary) of the anterior part of the skull. Nearly nothing is known between these two parts of the skull. Only a jugal and a maxilla fragment. I'm not convinced by the reconstruction of the skull of this dinosaur presented by Gomani in the Malawisaurus paper. The reconstruction of the maxilla is highly speculative; this bone is represented by a very small fragment, which is insufficient to know the exact shape of this bone. The exact shape of the maxilla can not be deduced from the shape of the bones that surrounded it, because most of these bones are unknown.

According to the shape of the premaxilla, the skull was probably high, indeed. But it is not impossible that it was also longer than we think. We need to find new elements of the skull (including at least a complete maxilla).

Good point... Malawisaurus's head could be restored several different ways. The deepness of the back of the jaw looks very strange in Gomani's version.

One other thing - this Astinganosaurus has extremely long shins. Longer than the thighs. This is wrong as no sauropod ever had tibiae longer than the femora. There's also one excess outer foot claw, and no thumb claw! (There is proof that most titanosaurs probably had thumb claws, their joints were just very loose and mostly cartilage, and so they often dessicated and the thumb claw and phalanges got washed away).

There's no good skeletal of this creature yet, but I've read the paper, it looks a lot like Malawisaurus.

I have just a skeletal of Malawisaurus

The link didn't work. I have a skeletal, but it's rather old and outdated. I'm gonna go with Zach Armstrong's when I do it, which is...I dunno when.

Danke, es liegt vielleicht auch daran das er eher klassische Proportionen hat und ich diesesmal ein einigermaßen vollständiges Sklett eines nahen Verwandten als Vorbild hatte

naja, vom körper her sind die proportionen schon klassisch, aber die beine sind schlanker, das sieht ut aus,es lässt ihn "eleganter" ausehen :D
