Card Trivia:Hyper Hammerhead
- This monster appears in the artwork of "Lost World".
- This monster's fossilized remains appear in the artwork of "Fossil Excavation".
- This card's name reflects appearance of this monster's head; its "nose" resembles a hammer's head hitter and the spikes at the back of this monster's head resemble the hammer's "claw" (the part that removes hammered-in objects).
- This card is one of two Dinosaur-Type monsters that returns a monster to the hand, the other being "Jurrac Ptera".
- In that sense, this card's effect is similar to that of "Mist Valley Soldier", albeit the latter's lore explains this differently.
