Description
I used to draw these kind of things a lot as a kid, but had completely forgotten about it. Decided to do it give it a try since it's like almost ten years ago or so.It's rather quick and some things are indeed of, I think, so I'll give those a quick summary:
Protoceratops and Velociraptor are a little bit too large, I think, but compared with each other they're quite alright.
Not entirely sure about Pachycephalosaurus, I draw those kind of animals as good as never.
Stegosaurus is small! I used Scott Hartman's "How big is your favorite dinosaur?" size shart, but ended up drawing one of the smaller specimens apparently. Steg could've gotten quite a lot bigger than shown here.
Iguanodon might be a bit too small too. You could definitely add a meter more in its length, I think, even though it's a massive animal already here.
Spinosaurus is the theropod I have the most difficulties with in getting it right. Them legs, so small, actually a bit too small... Here are the right proportions: media.farsnews.com/media/Uploa…
Note that I made this one a thick-skinned underwater running theropod with extra tissue on its sail to prevent it from falling over. (don't know if I gave it enough soft tissue for this though)
I'll probably make another one where I'm more sure about the animal's sizes. And maybe more dinosaurs in it too.

No, the limb material still belongs to Spinosaurus. Sigilmassasaurus consists only out of some neck vertrebrae for now.

Your very welcome !
Let's see what future brings. Maybe an adult spino's leg prove the bipedality
👍: 0 ⏩: 1
Well, there are still no arguments at all for a quadruped Spinosaurus and the important material regarding the limb size is from a young, sub-adult specimen. It's not like it was suddenly going to start growing some "traditional" proportioned legs at that age.
Anyway, the bipedality still stands tall for sure.

Only time shows; after all nobody expected 2014 model is actually a combination of two different species; right ?
Maybe the leg slightly gains length until fully maturing; even a few centimeters important after all !
Though didn't the model of 2014 put subadult legs onto an adult ? Maybe we just need to see how legs look in an actual subadult or have to wait until some miracle like Sue
👍: 0 ⏩: 1
Those few centimeters extra aren't going to do much, I fear.
No, the remains they found of the subadult were hindlimb and pelvis material and such. They simply scaled that up to adult sizes and then added the other adult Spinosaurus remains we had already to come to the 2014 model. The rest got filled up by looking at relatives.

Hey slightly longer means slightly longer !
I still think more fossil discoveries might change things; maybe turns out the leg might belong to another species. I read as they assumed adult proportions; as far as I know most of the 2014 speculations were erroneous; so only time would show or clear things up
👍: 0 ⏩: 1
Yeah xD
Could be, but I'm not so sure about misidentification that you're talking about. It could be of course, but for that we're going to need completely new limbs and pelvis material and get proof that those are from Spinosaurus. Sounds a lot like 17th century palaeontology, we don't work like that anymore to make such obvious mistakes, I think.
👍: 0 ⏩: 1
Well; Something similar happened I remember; I am not sure what's the name of the case but the paleontologists misidentified two separate avian like dinosaurs as one species; I am not sure about the name of the case although
👍: 0 ⏩: 1
That's Archaeoraptor. It were two fossils willingly glued together (one part was Microraptor I believe) by Chinese amateur fossil collectors to earn money. Digging up fossils is big business there for poor farmers and villagers.
The scientists bought it because they weren't aware such fraud happened in palaeontology so they simply couldn't expect the fossil to be false first. Nowadays they know better and things get checked carefully. Especially considering that kind of tricks.
Spinosaurus got criticism because some material was already collected by amateurs too so there was doubt about how legit those fossils were. I'm not aware of Ibrahim and co. not having proven that argument wrong though.
👍: 0 ⏩: 1
Oh; I didn't know they do that kind o thing On purpose... Well at least poor Chinese earned some money; that's the bright side of things
Well; I heard there's a need for a new model especially after the sigilmassasaurus became a valid genus\species.
Sorry very much for late reply I had lost contact with deviantart; because of my little depression thing
👍: 0 ⏩: 1
I haven't heard of that. I don't really see any problems with our current understanding of Spinosaurus. I'd rather have more bones of Sigilmassasaurus so we can get a better view of what that dinosaur looked like.
No problem, I can only get on DeviantArt in school atm because internet is down at home.
Hope you feel better already

I meant the 2014 knuckle walking thing; but I follow this model also known as the
'' pelican spinosaurus ''
2.bp.blogspot.com/-5G9wUvmoo4c…
But to be honest; legs weren't too much small in my view
Thanks a lot ! I am able to answer so; indeed I am better
👍: 0 ⏩: 1
Ah, okay. I understood you wrong then.
I followed that model too here. It was the most accurate and realistic answer to how it walked on land for me at the time. However I think I'm going to go for the belly slider technique if I draw him next time on land, which isn't quickly going to happen though. I need to do an underwater running scene after I saw Duane Nash posted a new article on his views about Spinosaurus: antediluviansalad.blogspot.be/…
Glad to hear

Oooh; I read that one ! The illustrations are very good too; hippopotamus (fatty) spinosaurus does looks so funny. But to be honest it seems very odd; I mean lonely spinosaurus babies ? They were probably protected by their mother father or both.
Thanks
👍: 0 ⏩: 1
Don't know, crocodiles don't protect their young either after a while so I wouldn't be surprised if some dinosaurs abandoned their young too after a few months. After all baby crocodiles do just fine on their own, a little Spinosaurus wouldn't have any problems with it either, I think. They sort of had the same lifestyle and were as Duane Nash depicted them, more mobile then their parents on land.
👍: 0 ⏩: 1
Well parental care in crocodiles really does vary; the most shortest crocodile who has parental care is gharial and they cafe for their hatchlings for weeks even a month maybe.
The false gharial doesn't have any parental care nor nest protection either but some crocodiles like saltwater & Nile do take care of their offsprings for months (even year\s recorded) and even known that males do assit them; they really do differ from each other.
However; considering That the Dinosaurs are also closer to the avians & almost all avians had parental care (social behaviore even pointed in theropods) some sort of; Spinosaurus might even be Monogamous; as most semi aquatic birds are. Most semi aquatic birds are also extremely good parents. (The most exaggerated one ? You know. The penguin 
(Nobody cares that the pirate gulls that ate penguin babies HAS to feed their own hatchlings too)
(Or the pelicans who literally marauding othr birds & animals nests has to feed their young)
I think if even a gharial with stubby legs could be an unexpectedly well defender; I would theorize how ferocious a spinosaurus parent\s might be.
👍: 0 ⏩: 1
Indeed, I really wouldn't want to have such an angry parent coming at me...
👍: 0 ⏩: 1
An angry parent; that can capable of gulping a human; even if it had a pelican like patch it might kept the human alive before feeding him\her to its babies
That would make a very good action\scary movie scenario

OOH I love these! Much better than www.google.com/search?q=dinosa…
I mean seriously! LOOK AT THE PACHYCEPHALOSAURUS! THAT THING COULD FIGHT GODZILLA AND LIVE TO TELL THE FREAKING TALE!!!!!!!!!!!

Jesus Christ, you weren't joking. That thing could literally class as a kaiju.

I especially like the Pachycephalosaurus and the Iguanodon

A wonderful collective of species in a neat line-up, I'm having a hard time picking a favourite out of these but I have to give it to the Diplodocus. Fantastic work!

I like those color patterns! I bet you used Scott's new reconstruction for the Iguanodon too. 
👍: 0 ⏩: 1
Yes, that was the reason why I even decided to put it in here
Yeah, it's confusing. Duane Nash wrote some posts about Spino too, but he says it definitely was a short-legged theropod.
👍: 0 ⏩: 1
Did you read something about the sail? Why they reconstruct in this way? With this double hump... or how could I describe... :-D
👍: 0 ⏩: 1
Not really. What I did here is just follow the sail's shape, but not with the skin thight around the spines so it ends up being more rounded.
The extra soft tissue on the back is an idea I've heard about before: it replaces the weight of the Spinosaurus more to the back so it isn't front heavy anymore and thus can walk on its hind legs without falling over, Traheripteryx's Spino has it too. The upright neck comes from Adrea Cau, also a way to make it not front heavy: 2.bp.blogspot.com/-5G9wUvmoo4c…
It's that skeletal I used as a reference btw. Made the legs a bit too small here in my drawing, though.

All the dinosaurs look very fantastic! And, oh my god, Spinosaurus' legs tho....
👍: 0 ⏩: 1
Thanks
Yeah, very tiny, but I they look so small because I made him thick-skinned in here. If I had gone for a normal looking theropod his legs would've been a bit bigger.
👍: 0 ⏩: 0
WOW Spino really have short legs. Also why Diplodocus have a fat neck? Due apatosaurus recently discoveries?
👍: 0 ⏩: 1
It's actually a dewlap like iguanas or other reptiles have. The neck itself is pretty normal.
👍: 0 ⏩: 0
Stegosaurus is actually species dependant with regards to size. S. stenops is somewhat "small" (still rhino sized!) while S. ungulatus is quite considerably larger.
👍: 0 ⏩: 1
Ah, yes. I had forgotten about that.
What's with S. armatus btw? Somebody told me he and S. ungulatus are now considered the same.

It is a nomen dubium.

(I'm the one who told him about it) Would you happen to have any links/articles about this? I read it on Wikipedia but couldn't find any other sites about it, and I wasn't sure if it was a reliable source, so...
👍: 0 ⏩: 1
It has been officially sanctioned by the ICZN, so that is about as reliable a source as you can get. You can't read it online, but the reference is: Carrano 2013, Opinion 2320 (Case 3536): Stegosaurus Marsh, 1877 (Dinosauria, Ornithischia): type species replaced with Stegosaurus stenops Marsh, 1887, Bulletin of Zoological Nomenclature vol. 70 issue 2, pp. 129-130.
