Four species of Pakicetus fossils have been identified and named. Though partial fossils were found in the early 1980s, a complete fossil was not found until 2001. Pakicetus inachus was the first Pakicetus fossil taxonomically identified, in 1981, by P. D. Gingerich and D. E. Russell.
Creationists really hate whale ancestor fossils. Answers in Genesis noted in 1996 that "Pakicetus consists of only a few skull fragments.(!)" When much more complete skeletal remains were found in 2001, AiG had nothing to say about the development. Jonathan Sarfati wrote for the Institute for Creation Research that evolutionists believed it was not at all like a whale, which is the opposite of the truth.
