Spinosaurus Wasn't Aquatic New Theory Suggests

[stargatedalek]

I believe the technical term is punting? Don't remember where I heard that. Turtles do it too to conserve energy.

It's also been suggested as a realistic option for Spinosaurus for some time now, I believe since the first images of the skeleton were leaked before the Ibrahim paper.

Talk about the stuff of nightmares, a punting spinosaurus. Hippos were scary enough...
Actually seems plausible that spinosaurus did bounce around.

Oh, I do believe Spinosaurs are aquatic. I got into a discussion with a group of people about wither or not Spinosaurs were quadrupedal, tripodal (yes, someones argument was they were tripodal as in tail draggers), or bipedal based upon the fossils currently discovered. My argument was that they did not swim like a crocodile, but rather 'ran' across the bottom of body of water like a Hippo. This would allow them to be able to catch some of the larger fish that probably dwelled at the bottom of lake / river. If they were in a large body of water, they would be able to paddled / lunge up to the surface for a quick breath of air. While on land they had 2 modes of movement. Slow movement they would belly walk similar to a loon. For fast movement, I believe they would have lifted themselves up and moved in similar fashion to a Pangolin, though only for a short while. These modes would allow it to have some mobility on land.

I mean, the skeletal structure that is accepted now, is not built for terrestrial hunting. If it was, it would have a similar build to Baryonyx, or Suchomimus

They're gonna have to remake some toys...

Side note: I went to a talk that Nizar Ibrahim gave just a couple months ago. His story of how he rediscovered the Spino remains was fascinating.

Ah, I'm a tad behind. Interesting to see the discussion though. Is there a way to delete or merge my post?

Report it to the mods/admin.

In my opinion, I do think it was at least partially aquatic. It was likely wider than described in this source. Plus, my theory is that Spinosaurus had a hump on its back rather than a sail, and also since it had quite dense bones, it sank. But it could possibly inhale air into its lungs to adjust and make it float. Basically the opposite on how Plesiosaurs swallow gastroliths to help it sink. Plus the thought that it was short legged but still bipedal, a lot of people still think it is quadrupedal. I know not many people might agree with me, but it's just my opinion. We just don't really know too much about our water doggo Spinosaurus.
