In reference to the mummy Dr. Saroyan mentions dry air and dessicated mummification; Zack mentions as examples the Incan ice woman, the Tarim Basin mummies, and the peat bog Tolunda man. The first two are classic dessication mummifications under cold, dry conditions. But the peat bog mummies are found below the water line in peat bogs, they are very wet. They are also very leathery and preserved by the high acidity and high tannin levels and lack of oxygen in the bogs. The Tolunda man was so well tanned you could see his beard stubble.
The inspiration for this episode comes from a true case where a real dead body was found in a funhouse in California. The mother makes a reference to the source material when she confuses that the body was found in a funhouse instead of a maze.
Dr. Camille Saroyan (Tamara Taylor) is the anti-hero Catwoman, wearing a similar mask to Michelle Pfeiffer in Batman Returns (1992) (1992) and the rest of her outfit is similar to Halle Berry in Catwoman (2004) (2004), meanwhile Temperance Brennan aka Bones (Emily Deschanel) is dressed as Wonder Woman (Lynda Carter) in Wonder Woman (1975) from 1975-1979. Agent Seeley Booth (David Boreanaz) mentions the Lasso of Truth, a lasso which Wonder Woman uses in the comics and the TV show. Both costumes are from DC Comics. It is also mentioned that Booth's Squint costume is similar to Clark Kent (Superman's secret identity).
It is not at all surprising, nor is it a feat, for the private investigator to know that Angela legally changed her name, and what her name used to be.
Except under extreme circumstances, all records of legal name changes are available to the public and can be easily searched by absolutely anyone.
Temperance Brennan aka Bones (Emily Deschanel) does the Wonder Woman spin and speaks to Agent Seeley Booth (David Boreanaz) near the end of the episode. Wonder Woman is from DC Comics.
