For those of you artists who don't follow every last Facebook update on dinosaurs, I thought I's pass along this link. It describes Kulindadromeus, a Jurassic ornithischian from Siberia that is covered in a combination of scales AND fuzz. While it will probably take a while to develop a proper scientific consensus as to whether these are truly feather-like structures, elaborate scales, or some other epidermal structure, the take home message for you is that dinofuzz can now be inferred to be possible in essentially all dinosaurs. And furthermore Kulindadromeus has a scaly, dare I say almost rat-like tail to go along with its fuzz. So apparently the idea that dinosaurs couldn't contain both scales and fuzz is also incorrect (whether this applies to true feathers is not yet known).

my dear brother, Scott Hartman
about exist of  "gastralia" and evolution and physiological role of it in evolution of aquatic reptiles, please answer to my questions according your wonderful knowledge about anatomy:

1- according to Sea dragons by Ellis, Giant Pliosaurs had  "gastralia" and Mosausrs did not have "gastralia". Why?

2- Did exist "gastralia" in pliosaurs give them any advantageous or disadvantageous in compare with Mosasaurs that do not have "gastralia"? How and why?

3-What were role "gastralia" in Giant Pliosaurs?

4-A Pliosaurs never come to land, therefore, why they have  "gastralia"?
5- Do exist "gastralia" in giant Pliosaurs show us they dive to deep parts off sea like Sperm whales?

6-Do komodo dragons have "gastralia"? Why Mosasaurs do not have "gastralia"?

7-Do ancestors of Mosasaurs (Aigialosauridae) have "gastralia"?

8-Do lack of "gastralia" show a better adaption for aquatic environment?

Do you know who invented the name, pterosaur? :baffled: 
ScottHartman Featured By Owner 2 days ago  Professional Digital Artist
I didn't, but according to Wikipedia it was Johann Kaup who first coined "Pterosauria".

Okay, thanks.

Scott do you think this drawing is mine is anatomicly accurate?…
ScottHartman Featured By Owner Jul 20, 2014  Professional Digital Artist
It's generally pretty solid, but the back of the leg (behind the knee) seems to have not moved enough to keep up with the knee joint as it moved forward while sitting down.

Hello Scott Hartman. I have another thing to ask you. Some people appear to be of the idea that theropods (referring to non-dromaeosaurids) could use their hindlimbs and pedal unguals as weapons, or at the least, could use them to help pin a prey item that's fallen to the ground. Do you believe this is accurate? I thank you for your time.

It depends on the theropod. Any animal will use what it has in order to secure food, so I don't doubt that a theropod would use its hind limbs to hold down prey if it aided in catching dinner and didn't threaten to tip itself over (so a T. rex might be more likely to apply the technique to a Pachycephalosaurus or a juvenile Triceratops than a fully grown Tric), but most don't show any obvious adaptations until you get up to deinonychosaurs (dromaeosaurs + troodontids), where some evidence has accumulated that the specialized feet may have helped pin down prey while the predators stood on them and began eating them while still alive. Of course others have interpreted those claws as stabbing or slicing weapons, and that's also possible (and not necessarily mutually exclusive - animals can employ different techniques for different prey). One thing I don't find very likely is that the enlarged toe claws were used for climbing - their cross-sectional anatomy is not what I would expect in that case.

I love your work! Some of the best! Are planning a Life Reconstruction of the feathered Deinonychus and the feathered Struthimimus or Gallimimus sometime in the future (I'm struggling with finding proper anatomical resources because I've been trying to draw dinosaurs - They're very inaccurate and dated in my 'representation')?
