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.

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

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!

As much as I doubt this is how they looked I like it.

Let me see:

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

Yup, that is all yesterdays alright, good job.

Epic as Usual ! (Both idea and Art)  Wow! 
But kind of disheartening...

I never knew David Peters worked with spinosaurs and had a DA account :P

Only so many people would understand that joke.

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!
