Spinosaurus fishiness, part n
September 15, 2014
UPDATE the next day: Since I published this post, it’s become clear that the similarities in the two images are in fact convergence. Davide Bonadonna got in touch with Mike and me, and he has been very gracious and conciliatory. In fact, he volunteered to let us post the making-of images for his painting, which I will do shortly. I’m sorry that my initial post was more inquisitorial than inquisitive, and implied wrongdoing on Davide’s part. Rather than edit it out of existence, I’m going to let it stand as a cautionary signal to my future self. Stand by for the new post as soon as I can get it assembled and published….aaaand here it is.
Scott Hartman has already explained—twice–that the super-short-legged, “Ambulocetus-grade” Spinosaurus from the new Ibrahim et al. (2014) paper has some major problems. Those are both good, careful, thought-provoking posts and you should go read them.
I’m writing about something else fishy with the “new” Spinosaurus and, in particular, National Geographic’s media push. Let’s check out this life restoration, newly prepared for the Spinosaurus story:
And now let’s look at this one by Brian Engh from a couple of years ago, borrowed from Brian’s art page:
And let’s count up the similarities:
- Two spinosaurs, one in the foreground with its head mostly or entirely submerged as it bites a fish, and one further back on the right with its head complete out of the water;
- Two turtles, one in the foreground with its head out of the water, and one further back on the right fully submerged;
- A good diversity of fish swimming around in the foreground;
- Pterosaurs flying way back in the background;
And finally, and most interestingly to me:
- A curved-water-surface, fish-eye perspective to the whole scene.
All the bits are moved around a bit, but pretty much everything in Brian’s picture is in the new one. Is it all just a big coincidence–or rather, a fairly lengthy series of coincidences? Seems unlikely. Your thoughts are welcome.
