Films: Sound of Horror (1966)
Height/Weight: That of an average human.
Summary: You know what'd be really infuriating to the audience? Telling them there's a film with a dinosaur in it...and then rendering the thing almost completely invisible. That'll keep the money flowing for sure!
History: Once part of a clutch of eggs in a Greek cave, this creature hatched after it was uncovered via explosives, and grew into a full-blown killer. As it waited for its siblings to hatch, it killed anyone who dared enter its domain.
Notable Kills: Nothing special.
Final Fate: After its cave is bombed a second time, sealing it, the beast assaults the humans that did it, only to set off some dynamite in a car and get itself killed in the explosion.
Powers/Abilities: This thing appears to be permanently invisible to the naked eye. It also has a powerful hide that can take most damage.
Weakness: A weapon of great destructive power, like explosives.
Scariness Factor: 4-As asinine an idea it is to have a dinosaur in a movie no one can see, it's hard to deny the destructive potential of a creature you cannot see. Your death is going to be a brutal one, and you won't see it coming.
Trivia: -Back in the old days when dinosaurs were first discovered by people, the Greeks thought that they were the remains of humanoid giants and monsters.
-Some working titles for this film were "Sound from a Million Years Ago" and "The Prehistoric Sound".
