Spinosaurus aegyptiacus All Yestered by Rodrigo-Vega Spinosaurus aegyptiacus All Yestered by Rodrigo-Vega
Entry for the All Yesterdays Contest: [link]

-Yes, I have already made a wacky interpretation of Spinosaurus before [link] but I just kept coming with more! So this contest was a great opportunity to depic this enigmatic animal in a new light.
Traditionally spinosaurus has been depicted as an uber land-crocodile on steroids, but I beg to differ. I have already mentioned how I see a hump in spinosaurus as a much more feasive structure than the sail, more in the style of a bison than a Dimetrodon. I imagine that; feeding on a heavily seasonal diet of fish and carrion, the warm blooded animal might need to storage large ammounts of enegy during dry seasons.
-Further down the list of unlikelyness is the quadrupedal posture. Actually picturing the creature alive makes this much more feasible than it would seem at first thought. Most large theropods have tiny feet in comparison with their giant bodies, let alone the particularly massive Spinosaurus (add the fatty hump and it becomes plain ridiculous). The animal looks completely unbalanced in most modern depictions by standing just on its hind legs, as if would fall flat on its face. The price of having a center of gravity much closer to the nose than the vertical center of balance over the hind legs. Now picture that figure leaning down towards a water mirror to catch fish, and there is no possible way it wouldn't fall nose-first into the water.
Besides granting extra support for its weight, the quadrupedal structure would gran extra maneuverability while moving in shallow water. Spinosaurids are already well known for their well developed fore-arms and provided all the advantages they would provide, its not difficult to imagine the spinosaurs with slighlt longer fore arms, moving and acting like a giant grizzly bear.
-At the bottom of the bucket is the old fashioned trunk as it has been proposed for Diplodocus before. Established as a semi-aquatic animal the trunk might be very convenient. I also noticed how brown bears make use of extremely dexterious upper lips, when trying to catch salmon out of the air. Just thinking about that weird crest in the forehead and the high-up placement of the nostrils... got me wondering.

I LOVE THIS CREATURE/DINO! More please! Heart 
SCP-811Hatena Featured By Owner Jul 7, 2015  Hobbyist General Artist
Well, Spinosaurus was already confirmed to be a quadruped.
Rodrigo-Vega Featured By Owner Jul 19, 2015  Professional General Artist
Recently, yea! : D Way after I made this

So you kinda predicted the future there, pal (except without the big shnozz).

he looks like the blue guy from pink panther

In hind sight, this makes a lot of since when you consider that we use elephant/bear noises to help produce dinosaur roars! ^_^
Smerjeevski Featured By Owner Jan 18, 2015  Hobbyist General Artist
its so funny how since recent discoveries this might actually be how spinosaurus might have looked like LOL
DinoBrian47 Featured By Owner Nov 28, 2014  Hobbyist Traditional Artist
Judging by its appearance, it's hard to believe that is a dinosaur at all. Shrug 
Javor911 Featured By Owner Oct 1, 2014  Hobbyist Traditional Artist
Sorry mate, but this looks ugly as f*%k.
randomdinos Featured By Owner Oct 12, 2014
Do all dinosaurs have to be absolutely marvelous tho?

Take a goblin shark for example, it is ugly as f*k but still exists.
Javor911 Featured By Owner Oct 13, 2014  Hobbyist Traditional Artist
You are right. I understand and respect your point of view. Nod Handshake

Well thanks! High-five!

They just confirmed stat the Spinosaurus was more than likely quadrupedal.…

That is already outdated

This is amazing!  I love seeing people's interpretations of the soft tissues of dinosaurs.  There's so little we know about those tissues, and stuff like this makes me giddy!
Imortal-Night Featured By Owner Sep 6, 2014  Hobbyist Traditional Artist
As much as I doubt this is how they looked I like it.
trisdino Featured By Owner Jul 19, 2014
Let me see:

Ugly, weird, highly unlikely, well drawn, creative, not technically impossible.

Yup, that is all yesterdays alright, good job.
Daemon-of-Thealia Featured By Owner Apr 9, 2014  Student Traditional Artist
Awesome view of this dinosaur, strange but so interesting :)
grisador Featured By Owner Feb 28, 2014
Epic as Usual ! (Both idea and Art)  Wow! 
But kind of disheartening...

randomdinos Featured By Owner Feb 27, 2014
I never knew David Peters worked with spinosaurs and had a DA account :P
Rodrigo-Vega Featured By Owner Feb 27, 2014  Professional General Artist
Only so many people would understand that joke.
Jdailey1991 Featured By Owner Jan 23, 2014
Reading the others' comments, I have a few questions of my own:

1)  Pressure sensors on the snout and the high location of the nostrils make the trunk unlikely (but not unprobable).

2)  The Nile Basin during Spino's time was a tropical swamp.  What's the use of a hump for?

3)  Walks like a giant anteater?  Does this croc get any wierder?  I thought being an ordinary quadruped was cool-looking enough.

4)  Relating to no. 3, I am tired of people calling spinosaurs fish-eaters simply because of their appearances to crocodiles.  Crocodiles eat A WHOLE LOT MORE than just fish!  Anyone seen the popular wildebeest river crossing?

Hm, very interesting!  I've never seen it thought of that way before!
Megeso Featured By Owner Jan 22, 2014
This is fascinating! Nice work!
PineRain Featured By Owner Jan 6, 2014  Hobbyist General Artist
I like it :)
The popular image of Spinosaurus always seemed somehow wrong to me. I've seen one other speculative reconstruction like this, and I think it's a lot more likely.
Squidremote Featured By Owner Nov 17, 2013
That's a really nice, intersting and fresh interpretation, since it's allways shown as one of THE superpredators.
Eclipse7299 Featured By Owner Nov 13, 2013  Student Artist
Wow this is great! Not even the best scientists would probably ever come up with this :) (Smile)  keep up the good work
Goldenbull Featured By Owner Oct 7, 2013
Impresionante  :) 10 /10 genio total jaja

ahora Es posible? o solo  una idea, algo de posibilidad creo suponer que tiene :), ya voy a ver esta idea en NatGeo, por cierto, para cuando un Megaraptor?
Rodrigo-Vega Featured By Owner Oct 9, 2013  Professional General Artist
Soy muchas ideas que vas desde -algo probable- hasta -bastante ridículo- combinadas en un solo dibujo :P
Guyverman Featured By Owner Sep 28, 2013
If any reptile had a flexible upper lip as proposed for various sauropods, I think it would've been more like the snout on that one species of turtle.
Guyverman Featured By Owner Sep 27, 2013
It almost looks cute!

If this were the case, maybe this animal would've at least been quasi-bipedal on land. However, I think that it's nostrils would still be where its nasal cavity is, with the lip dexterous.
I absolutely hate it, but I really admire your drawing skills and creativity. xD
Rodrigo-Vega Featured By Owner Sep 25, 2013  Professional General Artist
HAHA. Absolutely valid opinion. :D
Michael-Vincent Featured By Owner Sep 22, 2013  Hobbyist Traditional Artist
Dude!!! Genius!!!!

i love paleontology, and this is....AWESOME and plausible xD
Kerian-halcyon Featured By Owner Sep 3, 2013  Hobbyist Writer
While imagining Spinosaurus as being a carnivorous tapir isn't the first thing I had in mind (given that a hump would have to make an animal very heavy/bulky for swimming), it's nice to know that I'm not the only dinosaur guy out there that dislikes the image of Spinosaurus being an uber-crocodile.  ^^
Lazytroll Featured By Owner Aug 25, 2013  Hobbyist Artisan Crafter
impressive and interesting Sir. 
waynekmick Featured By Owner Aug 12, 2013  Hobbyist Traditional Artist
You have defiantly taken the possibilities of non- fossilized soft tissue structure to a new level. Very creative! When I see depictions like this one I get excited because it goes to show how little we may know based off of only the bones.
Kaijukid23 Featured By Owner Aug 6, 2013
the most logical theory for me..
Vinctia Featured By Owner Jul 4, 2013  Hobbyist General Artist
This could actually very well have been the case. Who knows? We'll only know for sure if we travel back in time or find a mummified Spinosaurus with tissues and all. Or a nice tissue outline on a fossil. I like this :3

Traheripteryx Featured By Owner Jun 7, 2013  Hobbyist General Artist
Well... faszinating!
StevenGordonArt Featured By Owner Jun 4, 2013  Student Traditional Artist
I absolutely, utterly approve of this. Not only have you presented solid reasoning behind such a dramatic restoration, but it looks realistic! Amazing work, I don't think I can look at Spinosaurus, or its close relatives, the same way now!
Davidy12 Featured By Owner May 27, 2013
Interesting theory but we know for a fact that every theropod was a biped not a quadraped.
Rodrigo-Vega Featured By Owner May 30, 2013  Professional General Artist
We also knew for fact that they were all carnivores, until Therizinosaurs showed up.
Wesdaaman Featured By Owner May 5, 2013  Student General Artist
You sure about this?

Besides, all Theropods are known to be bipedal, not quadropedal
Rodrigo-Vega Featured By Owner May 6, 2013  Professional General Artist
No, not sure at all!
I actually find this unlikely myself.
But then, also all theropods were thought to be carivorous and now we have Therizinosauria and the likes.
