I had this as the textbook to the general paleontology course I took as an undergrad at the University of Florida back in the late 1990s. I found it to be quite thorough and useful as a general intro, though as the field had already progressed significantly in many ways by that time (and moreso by now), I found it wanting for methodological or conceptual uses. I would certainly still recommend it as an intro to many of the key issues in paleontology - I still refer to it for reminders of some apsects of paleo that I do not encounter frequently in my work - but I would not consider it ultimately as useful as some other texts out there that are more recent if you are planning to start a career in paleontology.
