Well, perhaps a juvenile rather than a 'sauropodlet', but I hope that got your attention, at any rate.
Brian Switek (who surely requires no introduction here) commissioned this highly speculative fuzzy little Apatosaurus from me for his forthcoming book, My Beloved Brontosaurus, to 'visualize a point' and to 'shock readers a little and then explain the image'. It is reproduced in greyscale in the book, but this is the original drawing. I had Brian's permission to share this a while ago, but quite forgot to do so here (chiefly because I still feel ill-qualified as a contributor. Sorry, folks). It is perhaps timely that I chose at last to post this today, since it also happens to be Brian's birthday. I hope you'll join me in wishing him many very happy returns.
As usual, please open the image in a new tab for best viewing!
