Fossil Pokemon

The gang came to Grampa Canyon. They saw a lot of people holding picks and shovels.
"What are they doing here?" Tomo asked.
"Looking for Pokemon fossils." Ash answered. "Prof. Oak told me that fossils were recently discovered in this area." 
"I see." Brock said. "So these people are searching for fossils."
"Can we hunt for fossils please?" Tomo asked. 
"I don't see the problem with it." Ash replied. "What do you think Misty, Brock?"
Misty and Brock had nothing against it either.
Just as the gang began to search for fossils, Gary appeared out of nowhere.
"Why hello Ashy-boy." Gary said. "Here to search for fossils? You're wasting your time."
Gary then left.
Tomo didn't like Gary's attitude and was fortunate his brother didn't act that way.
Soon everyone began to search for fossils, but finding them was a hassle. 
No one knew that trouble was brewing in Grampa Canyon.
Team Rocket was in Grampa Canyon as well. They wanted to get a lot of fossils.
"If we collect a lot of extinct Pokemon." James said. "Not only will we be rich but Team Rocket will become stronger than ever."
"Meowth, is the dynamite ready?" Jessie asked.
"Ready and set." Meowth said.
The dynamite was for blowing the canyon up, so Team Rocket could find fossils easily.
Meanwhile the gang continued their fossil hunt. Suddenly Brock found two rocks. They both had shells on them. 
"I wonder what these are?" Brock asked. 
An old man, a fossil expert looked at them.
"Congratulations young man." He said. "You have found a Dome Fossil and a Helix Fossil. Take these two fossils to a scientist and you will obtain a Kabuto and Omanyte."
"Thanks." A surprised Brock said.
Ash, Tomo and Misty were happy for their friend and hoped to find fossils for themselves.
Suddenly they saw Team Rocket.
"What are you creeps doing?" Ash demanded.
Team Rocket revealed their plan as Meowth lit the fuse on the dynamite.
"Don't even think about it!" Ash shouted and released his Squirtle and Buizel. Ash, Tomo, Squirtle and Buizel chased after the fuse as fast as they could to put it out. Team Rocket ran after the four to stop them. But they were all too late; the dynamite exploded. Ash, Tomo and Team Rocket fell through a hole in the ground.
When Ash woke up, he discovered that he and Tomo were in an underground cave. 
"Are you all right Tomo?" He asked.
"I'm okay." Tomo said. None of them were injured.
"I'm glad I didn't have my backpack with me when we fell down here." Ash said. "My eggs are in there and they would have been broken. Come on Tomo, we need to find a way out of here." 
"Growlithe isn't here." Tomo said. 
"You're right." Ash replied. "And Squirtle's not here either. We must have been separated when the dynamite went off. Don't worry though, I'm sure they're okay and they will be with Misty and Brock."
Just then they ran into Team Rocket.
"Hey twerp!" Jessie shouted. "It's your fault we're trapped in this cave!"
"What was that?!" Ash growled back in a deep voice. "I'm not the one who lit that dynamite!"
They were about to argue some more when they heard growls. Soon they were confronted by fossil Pokemon.
Ash looked them up on the Pokedex. 
"Omanyte, the Spiral Pokemon. Although long extinct, in rare cases, it can be genetically resurrected from fossils."
"Omastar, the Spiral Pokemon and the evolved form of Omanyte. A prehistoric Pokemon that died out when it's heavy shell made it impossible to catch prey."
"Kabuto, the Shellfish Pokemon. A Pokemon that was resurrected from a fossil found in what was once the ocean floor eons ago."
"Kabutops, the Shellfish Pokemon and the evolved form of Kabuto. It's sleek shape is perfect for swimming. It slashes prey with it's claws and drains it's body fluids."
"The explosion produced by our dynamite must have woken them up." Jessie said.
"But this is a good opportunity." Meowth said. "It's now our chance to catch them."
Jessie and James agreed and sent out Arbok and Weezing to battle them.
While Team Rocket was dealing with the four fossil Pokemon, Ash and Tomo dealt with a second group of fossil Pokemon. Tomo was scared and held onto Ash. Ash rubbed Tomo's hair to calm him down and took out a Poke Ball.
"Since fighting type Pokemon are strong against rock type Pokemon, I choose you Primeape." Ash said.
His big monkey Pokemon huffed and got it's fists ready to fight.
"Use Dynamic Punch." Primeape's fists glowed white and he punched the fossil Pokemon really hard.
"Now use Hi Jump Kick." Primeape jumped and kicked the fossil Pokemon really hard.
Ash grabbed two Poke Balls from his pocket and caught Kabutops and Omastar. Then he passed two empty Poke Balls to Tomo. 
"This is a once in a lifetime chance, so catch them." Tomo grinned and tossed the Poke Balls at Kabuto and Omanyte. 
"Primeape return." Ash said. 
He and Tomo were relieved that the fossil Pokemon they had to fight were dealt with but Team Rocket was still having trouble with their own fossil Pokemon.
Outside the cave Misty and Brock were dealing with the rubble. Squirtle, Buizel and Growlithe were helping out too, digging away rocks and soil.
"I hope Ash and Tomo are okay." Misty said.
"So do I." Brock added.
He had his Geodude and Rhyhorn helping out.
Inside the cave, Team Rocket was still having trouble with their own fossil Pokemon.
Suddenly a loud roar was heard and the Omastar, Omanyte, Kabuto and Kabutops ran away in fear.
"Where did that roar come from?" Ash asked, holding onto Tomo.
His question was soon answered. A large grey pterosaur with wings flew over the group and landed on a rock, roaring.
Ash looked at it on the Pokedex. 
"Aerodatcyl, the Fossil Pokemon. A ferocious, prehistoric Pokemon that goes for the enemy's throat with it's serrated, saw-like fangs."
Ash grabbed Tomo's hands. 
"Let's get out of here!" He shouted.
Ash and Tomo ran as fast as they could, but Aerodactyl caught up to them and grabbed Ash with it's claws. He pushed Tomo out of the way before Aerodactyl grabbed him.
Meanwhile Misty, Brock and the Pokemon were still digging through the rubble, when they heard shouts and screams from the other side.
"What's going on?" Misty asked.
She soon got a answer when Aerodactyl flew out of the ground with Ash in it's claws as one of his fists was lit on fire. Tomo was holding onto Aerodactyl's tail and let go as soon as they were out of the underground cave.
Aerodactyl was flying into the sky still holding Ash.
"What can we do?" Misty asked. 
Squirtle was worried about his trainer. Tomo quickly ran to Ash's backpack to see if there was something in there to help. And there was; he found two of Ash's Poke Balls. Tomo opened them and out popped Charmeleon and Corviknight. 
"Ash needs help!" Tomo shouted, pointing to the sky. Corviknight saw the situation and flew off into the sky as quick as possible. 
He flew as fast as he could to save Ash, but Aerodactyl was too fast for Corviknight. 
Ash punched Aerodactyl in the face to free himself, but Aerodactyl held onto him tighter and tighter.
On the ground, Charmeleon was horrified by what was happening. Ash was like a brother to him and he wasn't going to let Aerodactyl get away with this. Charmeleon roared and then glowed. Tomo, Misty and Brock watched in awe as Charmeleon evolved into Charizard. Charizard then rocketed into the sky. Charizard and Corviknight worked together to save Ash from Aerodactyl. Charizard distracted Aerodactyl by unleashing Flamethrower. Then when Aerodactyl wasn't looking, Corviknight hit it with Steel Wing. Aerodactyl dropped Ash, but he changed form and flew in the air alongside Charizard and Corviknight.
"Finish Aerodactyl off with Fire Blast." He commanded.
Charizard's Fire Blast scorched Aerodactyl and it crashed to the ground.
"Let's return to land." He said.
Charizard and Corviknight followed him towards the ground.
After returning to land, Ash changed back and threw a Poke Ball at Aerodactyl and caught it. 
He then thanked Charizard and Corviknight for saving him and hugged them both. Then he noticed a Pokemon egg on the ground.
After the incident with Aerodactyl, Officer Jenny arrived at Grampa Canyon.
Ash informed her about everything that happened. She turned to the diggers.
"Everyone." She said. "As a result of this incident caused by Team Rocket, fossil hunting in Grampa Canyon is prohibited from now on." 
She turned to Brock.
"Because you found these fossils prior to Aerodactyl's rampage, you can keep your fossils but do not tell anyone they came from Grampa Canyon." 
Brock understood her request. 
"Ash, I'm going to drive you and your friends to the hospital. You need to get checked out for any injuries." 
"I hear that." Ash nodded. He and the gang then get into Officer Jenny's vehicle.
At the hospital, the doctors examined Ash's body with an X-ray; he was fine thanks to his dragon form's durability.
Tomo was hugging Ash like crazy; he had been really worried about Ash. 
When Ash contacted Prof. Oak, he was really excited about Ash capturing fossil Pokemon.
"There's a scientist on Cinnabar Island who specializes in fossils and will resurrect your Kabuto and Omanyte." The gang decided to spend the night at the hospital. 
Ash then removed the egg he found from his backpack and handed it to Misty. 
"I already have two eggs." He told her. "Besides I've known for a long time that you wanted your own infant Pokemon." 
Misty was happy and hugged him out of gratitude. Then the gang settled down to sleep with new Pokemon.
As for Team Rocket; they had left Grampa Canyon disappointed with their failure to capture any fossil Pokemon.
