Nessie wouldn't cause the uproar in paleontological circles that this one has. "A fat plesiosaur??? OUTRAGEOUS!"
Hopefully not getting too far off track, but when I was young my sister bought me a 2nd hand copy of a book at a garage sale about the Loch Ness Monster. It fascinated me because it seemed to be a fair attempt at a rational review of the topic, explaining the different studies that they had done, including underwater cameras which did show some stuff that could potentially leave you curious enough to want more study, etc.
In addition they tried to collect and analyze all the descriptions of encounters to date (which I guess must have been back in the 1970s) and see which of the possible explainations they best fit overall.
If I am recalling correctly I think that one of the best fits for the data was found to be a giant newt, or something like that, for which they provided an artists interpretation of. I did a quick internet search and couldn't find those images (and sadly my book is likely packed away in my attic somewhere), but I did find a blog with a sketch of a giant salamander that the author of the blog appears to be suggesting as a possibility for the Loch Ness Monster, as shown below.
It would be interesting to see something like that as a possible model or diarama, though sadly my carving/sculpting skills and ability to do models of living stuff isn't really that good.
Sorry for getting off track. I really like your work. Thanks for sharing your pictures.
