Other mistake: Early in the episode, when the body from the outhouse is in the lab, the gang are all wearing bio-hazard suits. Sweets' suit has an opening along the rear-left section of the facemask - perhaps 3" long, and a half-inch high - making the point of the suit completely useless. (00:05:10)

More trivia for Bones
Question: When Doctor Brennan is examining the victim's skull, she states that a "straight suture across the palatine bone" indicates that the victim was a native Japanese speaker. I've studied linguistics, but I've never heard of a person's native language actually affecting their anatomy. So, for example: would a person of Japanese heritage who was born and raised in the US and spoke only English be distinguishable from a person who grew up in Japan and spoke only Japanese, purely by their palatine bones? (00:06:10)
Answer: Since the palatine bone is a bone that helps form the mouth it has a lot to do with speaking. The shape of it differs a lot depending on your ethnic background. I would guess that they, in the show, meant that the person's bone tells that they were Japanese and that it was "made for the purpose of speaking Japanese." That's what I'd assume anyway. I've studied molecular biology though, so I'm not an expert on bones.
