Ancient Family Matters! (Japanese: ラムパルドVSトリデプス！！ Rampard VS Trideps!!) is the 107th episode of the Diamond & Pearl series, and the 573rd episode of the Pokémon anime. It first aired in Japan on December 18, 2008 and in the United States on May 23, 2009.
Byron, the Gym Leader of Canalave City and Roark's father, returns from his training on Iron Island. Ash and friends come to the gym in order for Ash to have his gym battle with Byron. Upon entering the gym Ash and friends find Roark and Byron fighting over who loves fossils more. In an attempt to prove his love of fossils Byron shows Roark, Ash, Brock and Dawn his collection of fossils, including his special Anorith fossil which is three times the size of a normal Anorith. Byron and Roark then begin to fight over who has the better revived fossil Pokémon, Byron's Bastiodon or Roark's Rampardos. Ash suggests they battle to see who's fossil Pokémon is better.
Before the battle Ash and friends are speaking to Roark where it is revealed that Roark is there to convince his dad to come home to Oreburgh City for his parent's anniversary. A flashback is shown in which Byron is shown leaving Oreburgh to go to Canalave City as the Pokémon League asked him to take over the gym their. He also states that Iron Island will be a good place for him to find more fossils. He leaves Roark in charge of the Oreburgh Gym where he was formerly the gym leader. He also leaves his wife behind in his move.
Roark starts the fight by having Rampardos repeatedly use Zen Headbutt, while Byron instructs Bastiodon to counter with Iron Defense. Ash notes how powerful Zen Headbutt looks, and Brock replies that he thinks Byron actually has the upper hand. Byron instructs his Bastiodon to use Flamethrower, which Rampardos dodges. Roark then has his Rampardos use Flamethrower and Byron counters with Flash Cannon.
Meanwhile Team Rocket has dug a hole into Byron's fossil collection. James and Meowth recognize how valuable the fossils are and the group decides to steal them.
Back at the battle Roark has Rampardos use his most powerful attack, Head Smash, which Byron combats with Iron Head. After the collision Bastiodon seems to have the upper hand. All of a sudden an alarm goes off and Byron calls off the battle to go check on his fossils. Upon entering the fossil room the first thing Byron notices is how expertly Team Rocket dug their entry hole and doesn't even notice his fossils are missing. He then goes on to talk about Team Rocket's escape hole which he concludes must have been dug by a machine. Roark has to point out that all of his fossils are missing before he notices. The group then jumps down Team Rocket's escape hole in an attempt to retrieve the stole fossils.
At the other end of the hole Team Rocket is seen emerging with a drill mecha carrying the fossils. They begin to walk away when Byron, Roark, Ash, Brock and Dawn peek their heads out from inside the hole. The group confronts Team Rocket. Team Rocket does a modified version of their theme. After they finish Byron begins a speech where instead of getting mad at them for stealing his fossils he tells them they should only dig their holes by hand and not use machines. Roark points out to him that these are bad people who stole his fossils and Byron doesn't believe that such good hole diggers could have taken his fossils. Team Rocket then admits to stealing the fossils.
Roark sends out his Rampardos and Byron sends out his Bastiodon to attempt to get the fossils back from Team Rocket. They attack the mecha which takes almost no damage. Meowth, who is controlling the mecha, then has it start throwing chunks of earth at Rampardos and Bastiodon. Roark instructs Rampardos to use Zen Headbutt on the mecha. It is stopped by some of the chunks of earth that are being thrown at it by the mecha. The mecha then picks up some larger chunks and throws them at Rampardos. As it seems Rampardos is about to be seriously hurt by the tossed chunks of earth Byron has Bastiodon jump in the way and use Iron Defense which blocks the chunks of earth. Byron tells Roark that his is why he wants Roark to worry about defense more. He then tells Roark to have Rampardos use Head Smash. The attack knocks over the mecha and Ash then has Pikachu use Thunderbolt. The mecha appears unaffected and gets back on its treads. Meowth says the Thunderbolts can't hurt the mecha but he is a little worried about all the head butts. Team Rocket begins to leave and Roark and Byron have their Pokémon use Head Smash and Iron Head respectively. The attacks create two small holes in the back of the mecha. Brock then suggests to Ash that he have Pikachu use Thunderbolt on the holes in the mecha. Ash does and the mecha explodes sending Team Rocket blasting off. The fossils were also launched but not as far and as they fall back down near the group Roark and Byron are both worried about the safety of the fossils. After they have landed the pair goes to make sure they are safe. Roark says they are all safe.
Byron then shows Roark his most prized fossil, a fossil of a Sunkern leaf. There is a flashback in which it is revealed that the Sunkern fossil was found by Roark as a child. It was the first fossil he found and he gave it to his father. Back in the present, Byron and Roark make amends. Byron then tells Ash that he is sorry he has kept him waiting for his gym battle but he will have to wait longer as his Bastiodon needs time to rest. Ash agrees and the gym battle is scheduled for the next day.
