The continuing Spinosaurus saga has reached its peak with Paul Sereno and National Geographic’s final, detailed description of the new version of Spinosaurus aegyptiacus. And things just couldn’t get weirder.
Are we witnessing the first ever “cetacean-like” dinosaur? It has the bone density of a hippopotamus, but neither the shape of the body or the limbs. It was an aquatic animal that supposedly could walk on land… but how? Seeing the mind-boggling limb proportions, I’m not convinced of all the lavish reconstructions I’m seeing around, and specially those illustrations that pretend to have it easily walking on land… the hind limbs are extremely small and , by themselves, I don’t see how they could have withstand the incredibly long horizontal body and tail on solid ground… On top of that, those forelimbs are not for quadrupedal walking (neither knuckle walking as it has been suggested)… So how did it managed to walk on land? I have a true obsession to try and make any reconstructions as anatomically believable as possible… and have come with this work in progress I’m presenting now: a combination of ancient whale-like animal and a seal… Don’t forget the dimensions (15 meters long)…could it be we are seeing the first dinosaur that actually was in the process of evolving into a “whale dinosaur”?
For me this only stresses the fact that Dinosauria is a “Class” just like mammals are! The common root and immense diversity of these animals can’t be denied!

Here’s the original sketch as I started working on. l’m using all the available material, so, as Thom Holtz and Scott Hartman have wisely stated, unless something is wrong with the limb proportion (the arms are after all a composite)… well what you see is what you get and we have to abide by the current evidence… This may change of course, but in the meantime, I don’t regret the destruction of yet another Spielbergian-oriented fantasy… and with a monster even more incredible than any fantasy!
