This one started off with so much promise
as the animators at the National History Museum (NHM) in London assembled their version of the ornithocheirid pterosaur, Anhanguera, bipedally (Fig. 1), as you’ll see when you click on the video under ‘References’.
Unfortunately there were some morphology issues (compared in Fig. 2):
- wings too long
- sternal complex missing
- gastralia missing (but rarely preserved in ornithocheirids)
- feet way too big
- skull too small
- tail too short
- not sprawling
- free fingers too big
- wing fingers should tucked tight against elbows (in the same plane)
- one extra cervical
- anterbrachia too short and gracile
- elbows overextended (in Fig. 1)
- too much weight put on forelimbs, center of balance (wing root) should be over the toes
- Prepubes are extremely rare in ornithocheirds, but when present they are tiny, putter-shaped and oriented ventrally in line with the bent femora, not anteriorly
Also unfortunately, the video quickly devolved
to the invalid and dangerous quad launch, when (doggone it!) it was all set up to do a more correct and much safer bird-like launch. The laws of physics and biomechanics are ignored here, but at least David Attenborough narrates.
Attempts to convince readers and workers
that the quad-launch hypothesis cheats morphology and physics (as recounted here and at links therein) have so far failed. But I’m not giving up. So, if anyone has a connection to the NHM in London, please make this post available to alert them of their accidental foray into wishful thinking and inaccurate morphology.
