Numbers of hominid fossils, from Talk Origins
Lubenow (1992) found that there were fossils from almost 4,000 hominid individuals catalogued as of 1976. As of 1999, there were fossils of about 150 Homo erectus individuals, 90 Australopithecus robustus, 150 Australopithecus afarensis, 500 Neanderthals, and more (Handprint 1999). Foley (2004) lists some of the more prominent fossils.
Pretty cool. What species are the other 3,000+ fossils? Some are not classified precisely, I expect, being too fragmentary or just not studied in detail.
