More Fossil Pokemon

The next day...
The gang visited the Oreburgh Museum with Roark. At the Oreburgh Museum there was an exhibition of a giant slab of coal, old tools and helmets miners used in the old days and also an exhibition of fossils. To the gang's surprise they learned that the museum resurrects fossil Pokemon from fossils with three special machines called the fossil-reviving machines and keeps the Pokemon after reviving them from the fossils.
"It's been a while since we were near fossils Brock, Tomo?" Ash said.
"You're right." Brock said. "We haven't seen fossils since we were in the Hoenn region."
"Oh, you kids have seen fossils before?" A man asked.
This man was the museum director Dr. Kenzo. 
"The truth is I have a Aerodactyl, Kabutops, Omastar, Armaldo and Cradily." Ash said.
"I have a Kabuto, Omanyte, Anorith and Lileep." Tomo said.
"And I have a Kabutops, Omastar, Anorith and Lileep." Brock said.
Roark and Dr. Kenzo were surprised to hear that.
Dawn already knew this because they told her earlier.
"Well you kids should come to the mine with me." Roark said. "I can show you more fossils there."
Ash, Tomo and Brock accepted the offer, but Dawn wanted to go to the Pokemon Center.
"Okay, we'll see you back at the Pokemon Center after we've finished visiting the mine." Brock said.
So the boys went with Roark to the mine and Dawn went to the Pokemon Center.
In the museum there was trouble.
Six men, a group of thieves, were intending to steal the fossils and one of the fossil reviving machines.
"All set boys?" One of the men, the group's leader asked.
"We're ready boss."
"Good." The boss said.
He then pointed to four of the men.
"Get ready to take the fossil reviving machine." He told them.
"You grab the fossils." He told the last member of the group. "I'll create a distraction."
"Let's go." They went their separate ways.
Meanwhile
Dawn had just arrived at the Pokemon Center. The TV in the center showed a broadcast with Marian and she revealed a Pokemon Contest was being held in Floaroma Town.
"That's where I'll obtain my first ribbon." Dawn decided.
Back with Ash, Brock and Tomo
They were walking near the Oreburgh Mine.
"Doesn't this remind you of Grampa Canyon?" Ash asked.
"Yes, but that place didn't have any coal." Brock said.
"I wonder if we'll find any fossils here." Tomo said.
Just then Roark walked up to them.
"I take it you kids like fossils too?" He asked.
"Yes." Ash answered. "I especially like looking at Helix, Dome, Old Amber, Root and Claw Fossils."
Roark smiled.
"Then you will like looking at the Skull and Armor Fossils too." He said.
"My Cranidos came from a Skull Fossil and a Pokemon known as Shieldon comes from the Armor Fossil." He explained.
Ash looked Shieldon up on his Pokedex.
"Shieldon, the Shield Pokemon. A Pokemon that lived in jungles around 100 million years ago. It's facial hide is extremely hard."
Roark then talked about how much he loved fossils like a maniac. The three boys just looked fed up.
Back at the museum
The staff there was in a panic.
The six thieves successfully stole a fossil reviving machine and some fossils. They were laughing about their success outside the city. What they did was have some Rhydon take the machine from underground, while the boss used his Persian to pretend to cause mischief in the museum as a distraction.
"I can't believe how easy this was." One of the men said. "I mean, the security there is terrible."
"With this machine and these fossil Pokemon it will be easier for us to steal more." Another said.
"Would you get ready to place them in the machine?" The boss asked the man that stole them.
"Hey boss." The man said. "The machine shows that a fossil is being revived now."
The boss looked at the computer screen on the machine and saw that he was right.
"It says this is that of an Aerodactyl." He said, amused.
The other men were amazed to hear that.
The boss sent out a Gyarados to get ready to fight the Aerodactyl.
At that moment the machine was ready and out came an Aerodactyl.
"Gyaradoa, Hydro Pump." The boss ordered.
A burst of water hit Aerodactyl. Then the boss threw a Poke Ball at the Aerodactyl and caught it.
"Nice one boss!" One of the men cheered.
The boss then came up with an idea; he decided to have the Aerodactyl attack Oreburgh City and blackmail it to pay him millions of Pokedollars.
The other men liked that idea and they went back to the city. They left the machine and fossils behind to pick them up later.
At the Pokemon Center
Dawn was talking to Piplup, Buneary, Ariados and Burmy. She was telling them about the upcoming contest in Floaroma Town.
"Okay Piplup, Buneary and Burmy I've come up with a move that we can use in Pokemon contests, so let's get to work on learning it."
Suddenly there was a screech in the air. It came from Aerodactyl.
Aerodactyl fired Hyper Beam at anything it saw. Everyone ran away in a panic and sought shelter immediately.
Meanwhile
Officer Jenny was at the museum after she received information about the robbery. The staff discovered through their security cameras that Aerodactyl was running wild in the city. 
"That Aerodactyl must have been the fossil we were reviving with our stolen machine." Dr. Kenzo said. "We must get to the Oreburgh Mine and tell Roark immediately."
Officer Jenny broadcast a message throughout Oreburgh City about Aerodactyl.
Dawn heard the announcement while she was inside the Pokemon Center and was worried about the others.
At Oreburgh Mine
Roark just got word about the Aerodactyl.
Ash decided to get his Aerodactyl from Prof. Oak.
Officer Jenny, some police officers and Dr. Kenzo then arrived at the mine.
"What happened?" Roark asked.
Before he could get a answer, Aerodactyl appeared along with the thieves.
"It's you six!" Officer Jenny shouted.
She was already familiar with the thieves.
"I should've guessed you were the cause of all this!"
The boss chuckled.
"I don't want to cause any trouble here." He said. "All you have to do is give me and my men a lot of money and then we will be on our way with the fossil reviving machines and fossils."
"Where is the machine and fossils you stole?!" Dr. Kenzo demanded.
"In the forest, safe and sound." The boss replied. "Now are you going to hand me the money or not?"
"Not!" Ash shouted. 
He then released his Aerodactyl. The thieves were surprised to see that and decided they could take it for themselves.
"Giga Impact, Aerodactyl." The boss said.
"You use Giga Impact as well Aerodactyl." Ash shot back.
The two Aerodactyl tackled each other. Ash's Aerodactyl was a lot stronger than the newly revived Aerodactyl and it was thrown back easily.
"Now Iron Head Aerodactyl." Ash said.
Aerodactyl headbutted the other Aerodactyl and knocked it out.
The thieves couldn't believe they had been defeated and prepared to release more Pokemon.
Roark's Cranidos used Zen Headbutt on them, knocking them out.
The police then quickly arrested them.
Roark grabbed Aerodactyl's Poke Ball and returned it.
Dr. Kenzo got it and promised that Aerodactyl will be taken care of at the museum.
"I'll recover the fossils and machine from the forest and return them to the lab." Officer Jenny said.
"Thanks for your help." Roark told Ash.
"Your Aerodactyl is something else." He said.
Just then Dawn came over to them; she had been worried this whole time.
The boys told her that everything was alright and Aerodactyl was in better hands. 
Suddenly Cranidos glowed and evolved into a bigger version of itself.
"Cranidos evolved into Rampardos." Roark said.
Ash looked it up on the Pokedex.
"Rampardos, the Head Butt Pokemon and the evolved form of Cranidos. It's powerful headbutt has enough power to shatter even the most durable things upon impact."
With Cranidos now a Rampardos, Ash knew he was in for more of a challenge when he faced Roark.
