Nice find. Was the skull that Mr. Richards (presumably Dr. Richards by now) is posing with... a reconstruction of what they thought it should have looked like based on the amount of material they actually found? From the schematic diagram there is a small section of a brownish stippled color depicted. The rest is in black and white. My guess is that brown stippled area is all they found. So lots of conjecture is at play, it would seem.
Interesting to say the least. Thunderbird, phoenix, puff the magic dragon, rocs ,may not be so fanciful after all.
Did you ever read “The Lost World” by Sir Arthur Conan Doyle? Same author of the Sherlock Holmes series.
It has spawned many, many movies, since it publishing in 1912.
In it, the adventurers brought back a pterosaur to London!.................
