A PDF of Kingham (1962) on Astrodon
In 1962, Richard Frank Kingham — a student at Woodward School Washington, D.C. — wrote a four-page paper, with three further pages of line drawings, about the Early Cretaceous sauropod Astrodon (Kingham 1962). It was published in the Proceedings of the Washington Junior Academy of Sciences (which to no-one’s great surprise does not seem to be available online).
For a smallish high-school project, it’s been pretty influential. For example, Carpenter and Tidwell (2005) followed Kingham in considering Pleurocoelus to be a junior synonym of Astrodon (though neither they nor anyone else has followed Kingham’s suggestion that Brachiosaurus, including Giraffatitan, should also be considered a junior synonym). Matt and I cited it in the Brontomerus description (Taylor et al. 2011) and probably in other papers, and it keeps turning up in all sorts of places.
Yet there is — or rather, was — no PDF of this influential short paper. The community has been subsisting on nth-generation photocopies. So when Matt asked me a day or two ago if I could send him a PDF, I had to reply in the negative.
But I do have one of those nth-generation photocopies — most likely originally from Matt himself. So I ghetto-scanned it (i.e. photographed the pages with my phone), cleaned up the scans, concatenated them into a PDF and OCR’d the result. I sent it to Matt, and now I give it to you, the community. Enjoy!
