Key points are not available for this paper at this time.
I gave my keynote talk last evening at the 28th Annual Tate Conference. I also passed out the handout shown above so people could have a handy reference for sauropod biology while I was talking. I have a link to a PDF version at the bottom of this post if you’d prefer it that way. Now that the talk’s done, I’m letting my “abstract” out into the world, here (link) and at the bottom of this post.
Matt Wedel (Sun,) studied this question.
