Season Nine: Episode "An Ermine Street Pub" carried a dedication to Peter Reynolds, one of the Team's consultant experts.
The Time Team Special: "The Real Knights of the Round Table" in 2008 carried a dedication to Paul Allen a medieval jousting re-enactor who died in an accident while filming that episode.
Role Ending Misdemeanor: Mick Worthington's role on the series came to an end after he refused to show Tony Robinson some data he's received over dendrochronology (and did so in quite a rude way). It was the first and last time a contributor had done so on the show. It was unclear whether this was because of the rude way he'd behaved over it, or whether it was because this violated the show's mission to show the archeological process inclusive of all its mistakes, puzzles, hurdles, and embarrassments.
