Continuity mistake: When Angela and Hodges are working out the size of the silhouette on the wall, as Angela says "which I deny", she's got a relatively serious look on her face. We then cut to a shot from the other side of her, and she's suddenly smiling.

Revealing mistake: When Bones and Booth are driving in his SUV talking about Abraham in the Bible, you can see that Bones' side window is lowered almost all the way down, but her hair is perfectly still and not being blown around as it normally would be.
Character mistake: In season 2, episode 4, when they find the girl buried under the cross, you can see her face, which means she was on her back, because her neck couldn't possibly bend that far around without it being noted by Dr. Brennan later in the episode (which it isn't). Later in the episode, however, Special Agent Booth tells Epps' wife that she was found buried face down.
