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.

If all species of the elephant family became extinct millions of years ago, do you think we would have been aware they had a trunk?

Well, I was questioning if a creature might have something on their skin that bone could never show, and if we would ever be aware of it.

Well that is abosolutely a valid question. We know for a fact that we often missed details of the soft anatomy of ancient animals, but also, many times we eventually came closer to a more accurate vision through means other than bone alone. The dinosaur books and magazines of my childhood told use we would NEVER know the real color of dinosaurs, but with todays modern science we know the color of some species down to individual feathers and scales!
So that's something to keep in mind : P
We will be wrong about many things for a long time, but very often with a lot of patience and hard work the missing pieces of the puzzles show up when we least expect them.

this is a very unique style on spinosaurus i love it (even if i side with the "uber crocodile on steroids" thing) and the dimetrodon has been depicted as a humped mammal creature as well (i like that design more then its original reptile style).
this is fantastic well done you should be proud the art style sort of reminds me of the stomping lands concept art style which is a big plus i love that style its cool
either way keep up the good work

You realized that spinosaurus' snout was carefully examined right? Trunks like these (reptiles have few muscles on their faces so such strong and muscular trunk on the face of a reptilian creature should probably be already counted as an innacuracy). Muscle attachments leave distinctive scars on the bones and if spinosaurus had such muscles, such marks would have been found. But instead, croc like "snout holes" were found, which means that it could not have had any extrmely muscular structure on it's snout, or the sensors on the snout would be useless.

Spinosaurus had both thick and thin sail bones, but as we see in modern animals only thick sail bones can sustain a hump, while both think and thick ones can sustain a sail (and in humps the top of the "sail" bones looks rougher than the rest of the bones, something that is not seen in spinosaurus). Also spinosaurus lived on a very rich environment and if it was a warm blooded semi aquatic animal, no droughts could happen or it would starve.

Every theropod would be unbalanced if we removed the tail, now if spinosaurus had a very long tail, it would be able to balance itself.

Bear lips are useless when catching salmon. The lips would not be able to hold the fish, the teeth would.

I made this to be purposefully silly, unlikely and fun.
Except the quadrupedal thing, I now stick to the idea of more-often-than-not quadrupedal-aquatic spinosaur.
Reply
:icondovahsaurpaleoknight:
Ah, sorry.

But spinosaurus would not be completely quadruped as it's arms were not made to walk and as it's legs were long enough to allow it to be bipedal. Also spinosaurids had very flexible necks. Keeping it's head more upright (I think this is the word I am looking for) and closer to the sail bones would move the center of gravity closer to the hips.

maybe when its swimming the trunk curves back to allow the sensors on the snout do there thing

The sensors would be useless on a head like this. The sensors pretty much prove that spinosaurus could not have had this head.

Nice interpretation, reminds me of an Grizzly bear/elephant seal

If Spino lasted longer than it did, I think its very likely it would look a little like this...

Small holes were found in the end of spinosaurus' snout. This discovery plus it's semi aquatic lifestyle suggests he had sensors on it's snout in order to detect it's prey (like modern crocodiles). This means that spinosaurus could not have this elephant like nose.
