Dinosaur King

While formerly considered a tyrannosauroid, hence its name and assignment to the Fire Attribute, Siamotyrannus has since been reclassified as a metriacanthosaurid. It is only known from its hip bones and the start of its tail.

  • Its arcade card never appeared in any release edition, but the barcode was available in the machine and can be played if the game is mildly hacked (that is, to scan the corresponding barcode for it). It is also featured in the website's Dinosaur Museum. This probably means that Sega had intended to release it but ultimately didn't (perhaps resulting from Dinosaur King's hasty discontinuation).
  • Being programmed into the arcade but without a released card puts it into a similar position as the unnamed "Golden Bird Move Card" and Tie Trap, though these Moves were never featured in other media, unlike Siamotyrannus.
  • Despite not properly being in the arcade game, it is part of both the DS Game and TCG without issue.
