The journalists go to visit Dr. LaRue, a palaeontologist, in San Pablo, Mexico, who excavated a dinosaur that has come to life. The dinosaur is now scaring everyone off, but why, and does it have anything to do with the Lost Silver Mine of Montazuma?
In Puerta Vallarta, Dr. Larue comes screaming warning two villagers that the dinosaur he's been excavating is alive. Just like that, the dinosaur appears and kidnaps Dr. Larue while the other two go to warn the village.
The gang arrives in the village of San Pablo to meet Dr Larue and the dinosaur he excavated. They spot a para sailor and decided to give it a try.
Shaggy helps Scooby get into his harness, but gets his leg stuck in it. Daphne starts the boat and they both get swept away. Their weight caused the rope to snap and they flew away into the village. They noticed the people running and see the dinosaur alive and ran away.
Daphne and Scrappy show up to find them and see the village in ruins, Scrappy falls in a huge footprint with oil in it.
They find the parachute torn and noticed that someone's there and Daphne gets an idea
Shaggy and Scooby lost the dinosaur and get caught in the parachute. They told them about the dinosaur that shows up. They hid in the jungle while the dinosaur walks away, Daphne finds something suspicious about it and they head out to find Dr. Larue.
They found more damage done by the dinosaur and more oil on the ground.
They follow a trail of more oil puddles unaware that they're being watch.
They find themselves standing right next to the dinosaur, Scrappy jumps on it's tail, triggering a secret path inside. Daphne and Scrappy go in followed by the others.
They enter a cave through the mouth which is an old mine shaft. Shaggy and Scooby run for their lives from the dinosaur. They land in ore cars and their stalker attempts to do away with them, but they bail out in time. They found a piece of silver ore on the ground, Daphne realizes that they're in the Lost Silver Mine of Montezuma. The stalker triggers a trapdoor they fell through. Upon landing they hear a truck outside picking up silver from the dinosaur, proving that the dinosaur is a silver processor. Scrappy takes control of the dinosaur and the truck driver crashes into a tree. The dinosaur's tail got caught in a cactus and the whole skin comes of revealing a crane was underneath it and the truck driver admits defeat.
Daphne asks where Dr. Larue is, but the driver confesses that there never was any Dr. Larue and he made up the whole dinosaur thing to scare off the villagers so he could steal all the silver. He's then taken to the Fererales and Shaggy is glad that the dinosaur was a fake. Scooby sits on a big egg and to everyone's surprise, a real dinosaur hatches and mistakens Scooby as his mama.
