So that people can vote on it, I'll go with an answer:

I do think that paleontology is mainly on-topic here but that the openly biological aspect of it (such as taxonomy and anatomy, and to some extant, evolutionary biology) should be asked on Biology.

Questions concerning:

• the fossilization process and the sedimentological impact of fossils
• the extent of the fossil record itself
• mass-extinctions and the impact of abiotic processes on biodiversity
• the place of biological organisms in geological cycles (Carbon, phosphorous, oxygen, silica cycles to name a few) and, more generally speaking, the impact of life on Earth
• the applications of paleontology to other fields of the geosciences (biostratigraphy, paleoenvironments, paleoclimatology, paleoceanography)

are very much on-topic here, I believe.
