Walker's heavy claw by ScottHartman Walker's heavy claw by ScottHartman
Updated: After nearly a decade and a half here is the overhauled skeletal. The overall proportions aren't all that different, but some of the details are. The midline crest has been moved back above the lacrimal, and I can now confirm that the odd downcurving neck seems to be a real thing, although it also uses some upwardly deflected almost cervicalized anterior dorsals to achieve it. The gray portion of the ilium is the part that was preserved as an imprint (i.e. there is no surviving bone from those parts) and so its accuracy depends entirely on the observations of the original excavators.

I hope to have more on my blog this weekend. 

Previous description: Baryonyx wasn't the first spinosaurid found, but it went a long ways in clarifying what these sorts of theropods looked like and ate. And it turns out they ate fish - although like modern crocodilians, Baryonyx almost certainly ate anything else it could get a hold of too (both fish scales and iguanodont bones were found in its stomach).

Cau posted something interesting on his site. The weird proportions could be due to misplaced vertebrae. Indeed, I always thought the body of their reconstruction looked overly long and until now I thought it was due to the tucked-in gastralia.

Yeah, I saw that. I have completely different data that comes to a similar conclusion. It looks like my blog post is slipping to next weekend, but hopefully not.

What's your opinion on the likelyhood that Baryonyx had weird modified feet of new spinosaurus?

Long legged theropods don't usually have full webbed feet, even those who live in swampy habitats. Paddling is much more effective when you have short stumpy legs. However, not even Baryonyx had it's legs proportioned like a stork... so who knows.

Remember that there is no actual proof of Spinosaurus having webbed feet either.

I wasn't referring to "webbed" feet, which seems like just-a-story to me.

I suppose that you know the icnites of Costalomo quarry in Sapin. There you have few threedimensional ones given to a large barioniquid. In those icnites there are not any webbing sign. What do you think?

I'm aware of the footprints (they are pretty incredible) but I'm not aware of any reason to assign them to spinosaurids instead of other large theropods. Has that been published somewhere?

Well I only found this note saladeprensa.usal.es/webusal/f…

In there has no discussion about the dinosaur that rpoduced the track, but in the museum itself, they give it to an spinosaurid or an allosaurid based on the direct fossil register in the zone.
I think we can take the size of the claws as reference and compare them to Allosaurus ones in order to discard it.

If you visit the quarry, the guides don't hesitate to say that those are spinosaurid footprints.

Any idea?

Doesn't Deinocheirus have similar flat feet? Headden claimed that the flat feet were an adaptation for walking on soft terrain, not a paddle. 
Reply
:iconscotthartman:
ScottHartman Featured By Owner Jan 17, 2015  Professional Digital Artist
Huh? Deinocheirus only has three toes (ornithomimids actually lose the hallux). The claws are sort of flat and spatulate in both, so perhaps that's where the similarity comes in? I agree that they (and webbing) work just as well for walking on soft substrates as they do for swimming. 
Reply
:iconlordofstamps:
LordOfstamps Featured By Owner Jan 17, 2015
Yes, that's what I was talking about. The feet of Deinocheirus are also wide (presumably to help a large, heavy animal support it's weight on soft terrain).

So the neural spines are taller now. One question Scott: Do you think Spinosaurus is a strange hybrid or the scientist need to study more the remains?

I think there are still scaling issues in Spinosaurus, and it _might_ have more than one taxa mixed in.

"..more than one taxa mixed in."

Namely, Sigilmassasaurus? I think we could end up having two gigantic spinosaurids living in the same time and place, one being more cursorial and the other primarily aquatic. In a biotope that is already dominated by large theropods. Cau said some interesting stuff in his blog but I might be jumping to conclusions too soon.

Anyway...I love how Suchomimus like the new Bary is!

:iconscotthartman:
ScottHartman Featured By Owner Jan 16, 2015  Professional Digital Artist
Yes, Sigilmassasaurus is the presumptive culprit.
Reply
:iconlordofstamps:
LordOfstamps Featured By Owner Jan 16, 2015
I bet "Spinosaurus B" is that other taxa, not Sigilmassasaurus. They provided NO evidence for a "Spinosaurus B"/Spinosaurus synonymy other than similarity of the "neotype" and "Spinosaurus B" and that is debatable. Elsewhere, others have pointed out differences between "Spinosaurus B" and the "neotype".

Remember kids. Say no to taxa overlumping. Even Greg Paul accused Ibrahim et al. of overlumping.

So, Scott, seems you've lengthened the skull quite a bit. Was fairly certain the lower jaw constrained a shorter skull.
Reply
:iconscotthartman:
ScottHartman Featured By Owner Jan 15, 2015  Professional Digital Artist
Actually the skull is exactly the same length as before. But with the moving back of the nasal crest to above the lacrimal it's much lower and so it looks longer.

The short version is that I trusted the fossils more. Aside from what I noted in the description, the vertebral column now has taller neural spines over the hips and front of the tail, the pelvis is larger, and the scapula isn't as long.

You know the strangest thing about your new reconstruction ? The proportions make Baryonyx look like some early
illustrations from the late 90's ! Like a kind of retro-action. I may be wrong but early Baryonyx drawings made it look like this slender, very gracile critter with an almost snake-like silhouette. Anyway, very happy to see this famous british fisher to be revamped. A new look to an old friend. ;) Thank you for this hard work ! :D

so is it official that Baryonyx and some other spinosaurs were bipedal? i mean with the new evidence of Spinosaurus with dinky legs would it also be possible that other spinosaurs shared the same structure too? or do we have actual skeletal proof that Baryonyx and others had much larger legs and whatnot? cus i've seen skeletons of a bipedal Spinosaurus and we know now that they weren't accurate so now its making us question others as well
Reply

I don't think the new Spinosaurus reconstruction is accurate, but yes, Baryonyx and Suchomimus are clearly bipedal.

:iconroflo-felorez:
RoFlo-Felorez Featured By Owner Jan 14, 2015  Student Digital Artist
ok so then its a matter of trying to understand the transition from bipedal to possibly semi-aquatic lifestyle, no?
Reply
:iconscotthartman:
ScottHartman Featured By Owner Jan 15, 2015  Professional Digital Artist
Is that a difficult thing? Ducks and penguins seem to have handled it just fine. Honestly the data at hand still doesn't really solve whether Spinosaurus (and spinosauruids in general) are more stork-like or truly analogous to early cetaceans (for that matter, it depends on WHICH early cetacean you are talking about).

oh i mean understanding it as in like .. having evidence to support why they eventually went from bipedal to semi-aquatic, cus surely they wouldnt do it cus they were bored.. explaining the analogy of ducks and penguins would describe it pretty well actually

Also Hesperornis - in fact, if Spinosaurus is as aquatic as they think I find it easier to entertain the idea of them being giant hesperornithid analogs than Pakicetus analogs.

ok so most earlier spinosaurs had legs more suited for a terrestrial lifestyle, is there any explanation for why they eventually developed smaller legs before Spinosaurus came into the picture? was it to be more suited for the waters?

Malcolmraptor Featured By Owner Jan 15, 2015  Hobbyist General Artist
I second Scott's answer, the "post-Ibrahim et al. (2014) Spinosaurus controversy" isn't really solved yet, and overall the spinosaurid hindlimb material available is quite scarce. I wouldn't jump into any conclusions concerning anything related to their leg proportions for now (though they do seem to be be fairly short, even more in Spinosaurus itself).
