My recent comment to RJS at Jesus Creed on the fossil record (with revisions):
It seems to me that what you often do is “fossil-mining” which is analogous to “quote-mining.” You bring up individual fossils that you think are “transitional” but you take them out of context in a way that is somewhat misleading. The context is the overall pattern in the fossil record, which is sudden appearance of species and stasis over time. The fossil you mention does not change that pattern at all. Moreover, the fossil may or may not be a “transitional” fossil. We would need to know more to know if it was part of a step by step pattern showing gradual change from one animal to a significantly different kind of animal. We generally don’t have those kinds of transitions in the fossil record, so there is reason to be skeptical that this particular fossil was part of that kind of progression.
