‘Prehistoric Life – Animated size comparison’ on YouTube

Figure 1. Click to enlarge. Pteranodon scene from Prehistoric Life video from Dane Pavitt. Incredible, excellent video, hearkening back to Giants of Land, Sea & Air - Past & Present (Peters 1986). Just a tweak or two necessary for the included Pteranodon. Extend those metacarpals and elevate that stance!

I’m just nit-picking here…
In Dane Pavitt’s Pteranodon scene just a tweak or two is necessary to match the otherwise excellent presented data. Elongate those metacarpals and elevate that stance, as shown by the added Pteranodon data (Fig. 2). The small medial fingers, alas, could not contact the substrate (given available data), but this is one instance in which, perhaps, the big wing finger could. More likely Pteranodon was bipedal, only resting on its big wings.

Post-crania Pteranodon

Figure 2. Click to enlarge. Various Pteranodon specimens known from post-crania. Note the yellow box includes one of the largest specimens, but it has an unfused extensor tendon process, which may mean it is a very large Nyctosaurus with fingers.

Remember,
pterosaurs were bipeds originally and often. Typically pterosaur beach-combers and waders made quadrupedal tracks. They had different proportions. We have  bipedal tracks for the germanodactylid ancestors of Pteranodon.

Earlier (March 2016) Dane Pavitt premiered
an incredible march of dinosaurs video (click to view below) now with 17+ million views.

I’m delighted to see these videos
continuing and expanding in action and scope a concept presented in book form over 30 years ago (Peters 1986). I wonder if Dane Pavitt had a copy as a child.
