Pot-bellied Pteranodon by jconway Pot-bellied Pteranodon by jconway
My new skeletal reconstruction of Pteranodon longiceps -- which turns out to have a surprisingly pot-belly.

You can get the whole story on the belly here -> [link]

Dear John Conway

I think discover a new thing…I look at Owen's reconstruction on Dimorphodon...Now have a Question....between skull and claw of Dimorphodon, We see a small skull with mammals teeth...Do you see this skull?

[link]


Do you know What is this small skull? a mammal (Lemur) as food or a baby Dimorphodon?

Do any scientist have spoken about this small skull in this picture until now?

you can publish an article about it and I am sure all of scientists will be surprised of such discovery

i like the pot-belly idea c: it makes them look sort of cute in my eyes

These animals had such strange and beautiful proportions.

Nice
How does this change the dynamics of muscles and leverage?

Despite seeing pterosaurs without pot bellies for my entire life, this in a way makes a lot more sense. Slightly better balanced with the big head and all. Fascinating pic!

Argh! Curse you and your besting me!

Really, I like this interpretation better, something about it feels more "balanced", and I always had trouble making any sense of the scapulocoracoid in the reconstruction I made. One thing though, the final tail vertebra extends into two long rods positioned right next to each other, it seems to be rarely preserved and may have been normally cartilaginous, ossified only in exceptional specimens (as is the case with many distinctive features in Pteranodon) (see Bennett 1987 and 2001). I'd also recommend taking some bits of Bennett's skull interpretation lightly, especially that post-frontal bone which is neither in the corect position for a post-frontal, nor does any pterosaur have a post-frontal (though Wellnhofer interpreted the ridge surrounding the orbits of "rhamphophynchoids" and basal pterodactyloids to be one).

Early on, I was really tempted to just say to myself "crushing"/"individual variation" and stretch the scapulocoracoid to fit. But I had a look at multiple specimens, and they're all like that, so no dice.

Chris told me in 2004 that he was wrong about the rods on the tail, and that they weren't real. I should revisit that.

The skull--yeah, I never got around to fixing that, I just traced Bennett. Want to combine skeletals? I'll send you the body if you sent me the head.

I'd like to see where he said that, all I could find said that the 1984 interpretation was wrong in some respects, but the rods were still there. A couple more things: When I last checked (meaning I may be out of touch with the latest information) metacarpals I–III are greatly reduced and do not articulate with the carpus, the wing phalanges seem a little too wide and I think the ulna/radius might be a bit short. Bennett also mentioned that based on the jaw and hyoid structure, a throat pouch was extremely unlikely. Finally, what's the latest on the two vertebrae that you show as fused to each other but not the notarium? I've suspected that the separation was due to either age or crushing, and that in a fully developed individual they would be fused to the notarium.

Combining skeletals? Sounds like a plan! Fair warning though, my skeletal is currently a complete mess in the original ai file.
