    No problem. During the periods in which you are banned, it shows as such under your Signature. So, we are all aware that you weren't deliberately ignoring my response. No offense taken. I chose a Ford Thunderbird because the first car I ever owned was a 1955A Thunderbird (I've had it for 49...

    Pterosaur "X" plane analysis

    Hi. CV 1&2 are fused into a single structure. They do not appear as separate bones though they in fact, are. All the Qn neck 'bones' you are looking at in Melbourne are sculptures (not casts of actual bones). If it were me, I wouldn't read too much into them. The Melbourne CV 3, such as it...

    There are some good papers in the research journals about flow across sharkskin. I don't remember any names off the top of my head. Pterosaurs have "fur" and bare skin, no feathers or scales.

    Pterosaur "X" plane analysis

    To keep it on topic, I don't think Denisovans were capable of flight. Having been involved in the production of several documentaries, I tend not to watch them. On the whole, they are too often geared toward keeping the maximum number of behinds glued to the sofa during the commercials. The...

    Pterosaur "X" plane analysis

    I'm familiar with the Queensland pygmies, the Red Deer people, the Flores folks, the Denisovans, and the early Abo variability. It looks to me like only Flores was a different species. The others seem to just demonstrate extremes of early modern and modern human variability. Speaking of...

    I wasn't aware of Fallout. Thanks. I too, have all of Norway's books except for 'The Seafarers', his unpublished flight log, and the 40 page fragment he was working on at the time of his death (I have read a few paragraphs of that) My favorites are 'An Old Captivity' and the screenplay...

    Henry, that's the largest seabird, not the largest volant bird in either span or weight (that's still Argentavis magnificens). Pelagornis sandersi was found a little over 30 years ago. Pelagornis was a lot more efficient flyer than Argentavis though. Just not as big.

    From Mark: On my book: Most of the time, you can just grab a copy from Amazon, but seemingly not so in Austrailia! Apart from the Kindle edition (Pterosaurs: Natural History, Evolution, Anatomy eBook: Mark P. Witton: Amazon.com.au: Kindle Store) I can't seem to find anywhere stocking it...

    I'm not much interested in the creationist stuff. Have a dear friend who is a fundamentalist Christian minister, and we agree that we have better things to argue about than religion. He attends some of my talks. He is also a flight physician and instrument flight instructor who owns a Cherokee...

    Pterosaur "X" plane analysis

    We really want to see Uluru and the Outback. My foster brother and I bought a J3 in 1965 to learn to fly. As a result, about 85% of my time is in a J3. Used to do search and rescue in it. Haven't done so in years, but to this day the majority of my landings have been off-field. Although I...

    Pterosaur "X" plane analysis

    Australia is one of the places on my bucket list (and my wife's). I would love to make contact with you, should we be lucky enough to make it before we croak. I don't have much hope of a man-carrying pterosaur either, though I have been an advisor on a project that was chasing DARPA funding...

    I will send you Bennett's paper on a USB stick by snail mail if you want it. You really should read it. Reid gave me a copy of his paper a good while back, so don't worry about that. As I've mentioned before, the Qn in the Melbourne Museum is an entertainment display, never intended as a...

    Pterosaur "X" plane analysis

    You seem to be interested in the scapulocoracoid (the C-shaped shoulder girdle). The ones in the TMM and Melbourne mounts are distorted sculptural constructs and don't look at all like the real thing. Here is a left one from a Qsp looking from outboard in toward the midline. It is propped up...

    Pterosaur "X" plane analysis

    What is a takeoff lope situation? If you mean that the animal moved along the ground to build up speed before taking off, they didn't. They just squatted and leaped from a standstill. No one has observed takeoff tracks. None have been found yet. Re the NG photo, his hand wasn't touching the...

    Here are three Quetz images you might find interesting. The sketch is John Conway's scale drawing of maximum joint articulations in Quetz. The position of the neck shown in gray is NOT flight position, it is neutral position -- quite a different thing. The drawing is of Qsp. Qn is...

    Pterosaur "X" plane analysis

    I looked at the photo. I hate to be the bearer of bad tidings, but what you are looking at in the NG photo is an optical illusion, part of the outboard left wing. It is Phalange IV-3 near the wingtip (the very short IV-4 forms the wingtip itself, but it is hidden by the human hand). IV-3 is...
