Yes, we’ve touched on a similar subject in a previous tutorial, but today I want to make a really important point about writing anything of substance, whether it’s a scientific paper, a novel or the manual for a piece of software.

Now consider a larger sauropod of length 2 x , as shown on the right above.

It’s a fascinating process: more of a history project than a scientific one. It’s throwing up all sorts of things. Here’s one. In 1992, the year after the mount went up, S. O. Landry gave a talk at the annual meeting of American Zoologist about this mount.
