Pterodactylus kochi skeletal by jconway Pterodactylus kochi skeletal by jconway
Something I've been planning to do for years, a skeletal of the Pterodactylus specimen I have a cast of. It's still not as accurate in the details as I would like (your really need the real specimens and a microscope to pin joint details down, for example), but overall it's reasonable.

didn't you forget the soft tissue crest on the black silhouette? i have seen a few skeletals done like that, so i'm just asking =P (the link shows something that looks like a low crest on the head actually, so the bigger was the surprise - if it isn't a shadow only)
it looks great non the less, i really like the impressions of the airsacks in the membranes, if that's what the grey is supposed to be ;-)
great job man!

Just a question; in this pic (and in this one [link]), you depict Pterodactylus' torso are relatively big [by pterosaur standards, and yet in assuming the Pterodactylus picture is yours, it has a much smaller body.

Is the size of Pterodactylus' torso speculative or is there evidence to state this picture is outdated? (and yes, I realise it is in the fact that the animal has no crest in here)

Actually, I think the two are consistent in their torso/wing ratios. The proportions aren't perfect in either of them, of course.

Cool skeletal.
Are you planning to go to that pterosaur meeting later this year?

Yeah, I put an abstract in for a poster and everything. God knows when I'll get time to do it!

coolness! Well I guess I'll see you there then. :)

That is if I get enough money to go...but the meeting seems to be too good of an opportunity to pass.

Dave Hone asked me if they could use some of my art but never heard of him after I gave aproval.
Btw your living at UK rigth? whats the best way to get from airport to hotel at nigth time+ are cabs expensive?

I didn't see any of your work that I remember, though a skeletal might have slipped me by...

Everything is expensive in London! If you coming here I could put you up for a while if you like. I'm away for three weeks starting Friday, but after that any time is fine. If you're coming sooner the tube runs until about 11:30pm, and is your best bet from Heathrow, otherwise taxis are going to cost you £25+, or perhaps a lot more, depending on here you're going. i would say gererally what you lose on a more convenient flight you make up for by being able to take to tube.

Two days in December? Well, stay with me then! We live in Shepherds Bush - which is reasonable central, and two spare beds.

I understand the black areas as postulated muscle mass and can make out your wing outline, can you explain to me what the grey stippled area in the wing represents?

Ah, air sacs. Air sacs are known to have existed in pterosaurs, and having extensive air sacs in the wing would have been an enormous aerodynamic advantage. The idea isn't as crazy as it sounds -- birds can in inflate their entire propatagium, and do so in certain types of flight. So I draw in air sacs wherever I see a aerodynamically fit.

Very interesting.

This makes sense, too.

Pneumatic anatomy seems to be an important gerneral archosaurian trait.

Spike.

Is P-Kochi one of the species that WASN'T a juvie?

What's the consensus with all those smaller "Pterodactylus" anyhow, are they babies of other species?

I'm just struck by how small it is.

I haven't read the paper, so I don't know. This is based almost entirely on one specimen, this one => [link]

Ah, Adelaide Uni has a cast of that one. And also has a cast of the solnhofen compsognathus.

The ANU has the mold, which is where I got it from (indirectly). It's obviously making it's way around Australia.

How hard would it be to get a cast??
Reply
:iconjconway:
jconway Featured By Owner Apr 19, 2007
No idea, I never knew who at the ANU owned it, and I live in England now. The National Dinosaur Museum was selling them in the shop when I worked there, you could see if they have any.

That's a good idea, thanks :)

(I could always ask if they could take a cast OF the cast at Adelaide Uni, does that cause problems??)

Not really, except of course the inevitable loss of detail caused by copying a copy of a copy (which is a copy of a copy itself).

Thanks. A lot of work goes into these drawings, but they're never quite done. I'm hoping to get a look at some more specimens later this year, so things may change.
