Wieland also says this:
Pakicetus was claimed to be a walking whale yet the type specimen consisted only of jaw and skull fragments.For a long time, we had no post-cranial Pakicetus bones. Since 2000, we do.
Some creationist sources are still running around pretending that we don't know what Paki looked like post-cranially. Creation science is somehow allowed to use old sources in misleading ways for some greater good.
Pakicetus is not the only such case among the cetaceans. See also: Ambulocetus Has No Pelvis and is Largely Incomplete? AiG strikes again!
