I only just learned a couple of days ago that Jim Valentine died. I don't think that anyone, even Stephen Jay Gould, did more to advance theory in paleobiology than Jim did. Jim was (and is) a huge influence on my research: and he was very helpful to me in both the beginning and middle of my career. He was 96, but even as of a few years ago he was quite active in the field. He won't be forgotten while anybody still does paleontology.
