Fossil

----
A Fossil (Japanese: Fossil) is a trace or piece of an organism from the past, such as a skeleton, shell, or leaf, preserved in the earth.
In the Pokémon world, Fossils of prehistoric Pokémon are items which can be revived into living Pokémon using techniques developed by the Devon Corporation and a research laboratory on Cinnabar Island. The two institutions purportedly developed their techniques independently of each other at around the same time. There are also other scientists around the Pokémon world who can revive Fossils using these techniques.
Pokémon revived from Fossils and the evolutions of those Pokémon are called Fossil Pokémon, or fossil Pokémon.Ancient Power Box, Product GalleryRestore & Renew! description, Pokémon.comFossil Pokémon Take Over Pokémon GO’s 2023 Adventure Week, Pokémon.comPokémon TCG Rulebooks
==In the games==
Scientists who can revive Fossils can be found in every core series game except the Generation II games and .
* Kanto: Cinnabar Lab or Pewter Museum of Science
* Hoenn: Devon Corporation
* Sinnoh: Oreburgh Mining Museum
* Unova: 
* Kalos: Ambrette Fossil Lab
* Alola: 
* Galar: 
Prior to Generation IV, Fossils were Key Items. However, from Generation IV and on, they are normal items, meaning that they can be traded freely between games. The table below summarizes the natural availability of the Fossils in the core series games.

In the games, relatively few Pokémon Trainers possess Pokémon revived from Fossils, since they are considered rare and difficult to obtain.
===Generation I===
In , the first three Fossils were introduced. They have also appeared in most of the later games. They can be resurrected into these respective Pokémon:
→	→	→
 	 	
The Helix and Dome Fossils are chosen near the end of the second basement passage in Mt. Moon, being guarded by a Super Nerd, but the player may only choose one to keep. The other one that the Super Nerd takes will be revived and put on display in the Fuchsia City zoo in front of the Safari Zone. The Old Amber is located in the secret part of the Pewter Museum of Science, which can only be accessed with HM01 Cut. In the regularly accessible portion of the museum are complete fossilized skeleton displays of and Aerodactyl.
A scientist in the Pokémon Lab on Cinnabar Island can revive the Fossils. The resulting Pokémon are level 30. 
There are no held items in Generation I, so fossils cannot be given to Pokémon to hold.
Lance is the first Trainer to be seen with a Fossil Pokémon, possessing an Aerodactyl due to its draconic appearance.
===Generation II===
No new Fossils were introduced in , and the three Fossils from Generation I have been removed from the games' data. In-game, the player simply doesn't happen to find any Fossil during their adventure, while the previously introduced Cinnabar Lab has been destroyed.
However, , , and are prominently featured in the puzzles located at Ruins of Alph. Of the three, only Aerodactyl is actually obtainable in the games via an in-game trade with an NPC in Kanto (for ). Omanyte and Kabuto must be traded from Generation I.
Lance, who is now the Pokémon Champion, continues to have an Aerodactyl on his team. In addition, Brock, being a Fossil enthusiast, has an and a in this generation's games, as well as the Stadium games in Gym Leader Castle. His fondness of Fossils is referenced again in the next generation of games when a man in Mt. Moon mentions that Brock helps excavate Fossils at the location, which implies that he excavated Omastar and Kabutops's Fossils himself.
===Generation III===
In , two new Fossils were introduced. They can be resurrected into these respective Pokémon:
→	→
 	
In Ruby and Sapphire, the player can choose one of either the Root or Claw Fossils at , and upon choosing, the other will sink away into the sand. In Emerald, however, while the player can only choose one initially at the Mirage Tower, they can retrieve the other later at the end of the Desert Underpass. In all three versions, Fossils may be revived by a scientist in the Devon Corporation building in Rustboro City and the newly resurrected Pokémon are obtained at level 20.
In the , the player can obtain the same Fossils as in the original versions: a required choice of the Helix or the Dome Fossil after fighting a Super Nerd in the second basement of Mt. Moon, and the Old Amber from a scientist in the secret area of the Pewter Museum of Science. Likewise, a Scientist on Cinnabar Island can still revive the fossils; however, the newly resurrected Pokémon are this time obtained at level 5. 
In , the Champion Steven Stone has two Fossil Pokémon, and . In , over the course of rematches, Roxanne will eventually gain a , an , and an for her team. In this game, Steven is no longer the Champion, but he may be encountered at Meteor Falls with a higher level variation on his original team that still includes his Fossil Pokémon partners. In , Lance continues to have Aerodactyl on his team, the resurrected form of the fossil that wasn't chosen at Mt. Moon can still be viewed at the zoo in Fuchsia City, and complete fossilized skeletons of Kabutops and Aerodactyl are still on display at the Pewter Museum of Science. 
In Generation III, all Fossils are Key Items, and cannot be traded to other games to be revived.
===Generation IV===
In , two new Fossils were again introduced:
→	→
 	
These Fossils can be turned into level 20 Pokémon at the Oreburgh Mining Museum.
In Diamond and Pearl, for the first time in the series, the Fossils the player is able to receive are dependent on the version played: Skull Fossils are available in Diamond only and Armor Fossils in Pearl only. In Platinum, whichever Fossil a player digs up will depend on whether the Trainer ID is even or odd. If the Trainer ID is even, the player will dig up Armor Fossils only, and if the Trainer ID is odd, the player will dig up Skull Fossils only.
In Sinnoh, when players travel to the Underground, they can find most of the Fossils by digging, along with several other rare items, potentially. After getting the National Pokédex, they can also find the five Fossils from the previous three generations. However, the chances of finding most of the previous generation Fossils, much like with several other items, follows a similar formula to the Sinnoh Fossils. This makes it easier to find certain Fossils which are found uncommonly, while the others become more difficult in the opposite version which instead are found very rarely. For example, the Helix and Claw Fossils have an easier chance to be found if the Skull Fossil is available, or the Dome and Root Fossil if the Armor Fossil is available. The Old Amber is the only Fossil whose ratio remains unchanged regardless of version as it will always be found rarely.
In Johto's Generation IV games, the Dome and Helix Fossils as well as the Old Amber can be found randomly by smashing breakable rocks outside Ruins of Alph. Root and Claw Fossils can be found randomly by smashing breakable rocks in the Cliff Cave after entering the Hall of Fame. Fossils found in can be revived as level 20 Pokémon at the Pewter Museum of Science. The Skull and Armor Fossils are absent from both games, so either they, or the Pokémon revived from them, must be transferred from Diamond, Pearl, or Platinum.
Starting in this generation, Fossils are considered to be normal items. As such, they can be held by a Pokémon and traded to another game.
Roark has a Cranidos, while his father, Byron, has a . and Shieldon are also used by two minor Trainers. After entering the Hall of Fame, can be spotted with other Trainers.
As in , Brock has an and a on his team in and also uses a Rampardos in rematches. Lance continues to have Aerodactyl on his initial team, but it is not used in rematches. 
===Generation V===
 once again brought a new set of Fossils to the Pokémon world:
→	→
 	
These Fossils can be revived into level 25 Pokémon using a machine in the Nacrene City Museum.
In Pokémon Black and White, one of these two Fossils will be given away by a person in Relic Castle, similar to how the Helix and Dome Fossils are originally obtained in the Kanto-based games.
In the sequels to these games, the Cover and Plume Fossils are instead given away by former Gym Leader Lenora at the Nacrene City Museum itself, which is only accessible after defeating Iris and entering the Hall of Fame. 
After defeating Ghetsis or Iris, Fossils that were introduced in previous generations will be given out by a in Twist Mountain, with one being given out per day. In addition, after defeating Iris and achieving Rank 15 for Join Avenue, the Antique Shop on Join Avenue has a chance of selling a mystery box that could contain any fossil, whether introduced in Generation V or earlier. And as with Generation IV, Fossils are regular items and may be held by Pokémon and traded to other games.
In Chargestone Cave, a couple of s battle with a and an in both sets of games. The potential Pokémon used by opponents on the Battle Subway are inclusive of both Fossil Pokémon and their evolutions, and Emmet uses in one of his rematch battles. 
In Black and White, both and Archeops are used by N in the final battle against him within his castle. 
In Black 2 and White 2, two s on also use teams entirely made out of Fossil Pokémon, and new Gym Leader Marlon uses in all battles against him. During Pokémon World Tournament competitions, many contenders use teams that may include of Fossil Pokémon: has ; Brock has , , and Aerodactyl; Erika has ; Falkner has Aerodactyl; Bugsy has ; Roxanne has Cradily, Armaldo, and Carracosta; Steven has Cradily, Armaldo, and Archeops; Roark has and Archeops; Byron has ; Skyla has Archeops; Marlon has Carracosta; Ace Trainer X has Archeops; and Ace Trainer Makina has Tirtouga. In the Rental Tournaments, all four Generation V fossil Pokémon are available to rent by both the player and all other competing trainers. 
===Generation VI===
Two Fossil Pokémon were introduced for .
→	→
 	
One of the two Fossils is given to the player in Glittering Cave and can be restored at the research facility in Ambrette Town. The resulting Pokémon are level 20. The Old Amber can also be collected after this by smashing breakable rocks in the back of Glittering Cave.
Gym Leader Grant uses and and their evolved forms in subsequent rematches. Champion Diantha also uses and .
After entering the Hall of Fame, the player can return to Glittering Cave and smash rocks to find the Skull, Armor, Plume, and Cover Fossils, regardless of version, as well as Root and Claw Fossils or Dome and Helix Fossils. 
In Hoenn's Generation VI games, the Root and Claw Fossil are collected and restored the same way as the original Ruby and Sapphire games. Restoring Fossils can be done at the second floor of the Devon Corporation. After battling /, a number of other Fossils can be collected by smashing breakable rocks at the Mirage spots. While the Old Amber can be found regardless of version, the Dome, Armor, and Plume Fossils are exclusive to Omega Ruby and the Helix, Skull, and Cover Fossils are exclusive to Alpha Sapphire. The Jaw and Sail Fossils are absent from both games, but may be transferred from X and Y - for as with Generations IV and V, Fossils are regular items and may be held by Pokémon and traded to other games.
===Generation VII===
Generation VII introduces no new Fossils, but the player may obtain most of the previous Fossils depending on the game. In Pokémon Sun and Moon, only the Fossils from Sinnoh and Unova are available. Their location is at Olivia's jewelry shop in Konikoni City, where the player can buy a Skull Fossil and a Cover Fossil in Pokémon Sun or an Armor Fossil and a Plume Fossil in Pokémon Moon. 
In Pokémon Ultra Sun and Ultra Moon, this has been expanded to include more of the previous Fossils which were absent from the original games. The Helix, Claw, and Jaw Fossils may be purchased alongside the Skull and Cover Fossils in Ultra Sun, and the Dome, Root, and Sail Fossils may be purchased alongside the Armor and Plume Fossils in Ultra Moon. Additionally, unlike the original games, any of these fossils can now also be obtained from Isle Aphun at Poké Pelago regardless of version. This is done from conducting a Rare Treasure-Hunting expedition (or an Interesting Item-Hunting expedition once the island has reached Development Level 3), where any of these Fossils have a very rare chance of being obtained. 
The Fossils can be revived at the Fossil Restoration Center on . The newly revived Pokémon come at level 15.
Unlike the other Fossils, the Old Amber is unobtainable in Alola. Instead, an can be obtained at Seafolk Village as a gift Pokémon.
Several minor Trainers use some of these Fossil Pokémon or their evolved forms as part of their teams. In addition for Ultra Sun and Ultra Moon only, Olivia uses both and during her grand trial. Later, when the player faces Olivia at the , they have evolved into and respectively as part of her upgraded team. At the Battle Tree, uses Aerodactyl, much as he had in for the Pokémon World Tournament in .
In Pokémon: Let's Go, Pikachu! and Let's Go, Eevee!, all three Kanto Fossils are obtainable in the same locations as they were in Generations I and III. On the second basement of Mt. Moon, the player must still make a choice of either the Helix or Dome Fossil to proceed with the main story, and the Old Amber may still be obtained from a scientist in the restricted annex at the Pewter Museum of Science after their first partner Pokémon has learned the Secret Technique Chop Down. All three fossils may be revived at the lab on Cinnabar Island, but this time the resulting Pokémon are obtained at level 44. 
Additional instances of the Kanto fossils may be obtained in these versions; a first for the Generation I games and their remakes. All three fossils may be found on the second floor of Cerulean Cave, where random rare items spawn occasionally.
During rematches, Brock adds an and a to his team in a reflection of their usages in Generation II, , and Black 2 and White 2. Lance still uses an Aerodactyl on both his teams, as does Blue in his rematch team in a reflection of its usage in his teams in Black 2 and White 2, Sun and Moon, and Ultra Sun and Ultra Moon. Either or may still be seen at the Zoo in Fuchsia City, depending on which fossil was not chosen in Mt. Moon, and the fossilized skeletons of Aerodactyl and Kabutops are still on display in the Pewter Museum's normally accessible floors.
===Generation VIII===
Generation VIII introduced four new Fossils, the most of any generation. Reviving Fossils in is a much different process than it has been in the past generations. Two completely different Fossils must be combined, by Cara Liss on , to form a chimeric Fossil Pokémon. These Pokémon all start at level 10, their genders are unknown, and cannot breed. These are also the only Fossil Pokémon that are not .
Fossil Combination		
 		
 		
 		
 		
Most previous Fossil Pokémon can be encountered in the in the Crown Tundra, often as wanderers, with possible exceptions being and (exclusive to Sword), and (exclusive to Shield), and Generation IV Fossil Pokémon (unavailable in both versions). While no attention is brought to the reason for their presence as wild Pokémon in modern times, with most of their Pokédex entries in Sword and Shield either mentioning they were revived from Fossils or glossing over their status as Fossil Pokémon entirely, 's entry in Pokémon Sword specifically mentions specimens that either escaped or were released after their revival. The only other clearly stated case is , whose Pokédex entries have been mentioning its status as a since Generation II. Data for their respective Fossils still exists in the games, but they cannot be obtained.
In , it is for the most part the same as , with only the Fossils from the first four generations available, with Skull Fossils being exclusive to Brilliant Diamond and Armor Fossils being exclusive to Shining Pearl. They can be dug up in the Underground's replacement, the Grand Underground. Unlike the originals, the Fossils from the first three Generations are available earlier; the requirement for them to appear in the Grand Underground is to defeat or capture or on the Spear Pillar, rather than obtaining the National Pokédex, but their encounter ratio is still the same depending on the version like the original games, excluding the Old Amber. Like in the originals, Roark uses a and his father Byron uses a , both as their highest-leveled Pokémon. and are used by a few Trainers, and the former evolves from Roark's Cranidos in the rematch with him, which can be done once per day after entering the Hall of Fame and obtaining the National Pokédex. In said rematch, Roark additionally uses an and an , two other Fossil Pokémon.
In , Fossils do not exist at all, in the game's coding or otherwise. Rather, only and can be obtained, and they can be found as rare spawns in space-time distortions in the Coronet Highlands.
===Generation IX===
Generation IX introduces no new Fossils or Fossil Pokémon, and , similar to the Generation II games, do not allow the player to obtain or revive any Fossils. The and lines are the only Fossil Pokémon present in the games, found in the wild in the Terarium.

===Pokémon the Series===
In , some Fossil Pokémon are in fact, not extinct, but have simply been hibernating underground for millions of years, as seen in Attack of the Prehistoric Pokémon, Shell Shock!, and Fossil Fools. However has used research to directly revive Fossil Pokémon, as seen in the Pokémon Chronicles episode Putting the Air Back in Aerodactyl!. Unlike in the , where Fossils of ancient Pokémon are resurrected into the skeletons of the prehistoric using a machine that recreates the missing organs that had decomposed away from the genes extracted in the remains, this Aerodactyl was in fact completely revived from a Fossil that was fully preserved inside of an Old Amber for millions of years and thus still had the memories of its past life.
====Jirachi: Wish Maker====
Butler tried to create a for Team Magma in a flashback Jirachi: Wish Maker from a fossilized remnant, but the experiment failed and Butler was kicked out of Team Magma. In the present day, he attempted to use 's power to complete the resurrection process to prove his theory, only to end up creating a monster resembling Groudon that needed to be stopped.
========
In Where's Armaldo?, Professor Proctor was shown to have used research to directly revive Fossils on Wales Island, his dream being to create a wildlife park filled with Fossil Pokémon.

Roark, as he does in the , has a Cranidos which evolves into a . Roark and his team retrieve Fossils from the Oreburgh Mine and give them to the Oreburgh Mining Museum. The museum's director Dr. Kenzo uses the Fossils for their Fossil revitalization program. Roark's Pokémon, as well as several other Fossil Pokémon revived by the Fossil Restorer Machine, appear in A Gruff Act to Follow!, Wild in the Streets!, and O'er the Rampardos we Watched!. Byron, Roark's father, also has quite a collection in his Gym. This includes the Fossil Pokémon , , , , , and , as well as a giant Claw Fossil. He also kept a leaf Fossil that Roark found when he was a child.
========
In A Night in the Nacrene City Museum!, a Fossil was first seen chasing Hawes, as he claimed it to be doing, but was later seen safely placed in a display case. Hawes later explained what it was to the trio. It was later revealed that the in the Nacrene City Museum was using its move to make the Dome Fossil float and chase after Hawes after he put its mask in a display case, thinking that it was a replica Yamask mask given to him as a gift from the company that made a replica after purchasing it from them for the museum.
Lenora gave a Plume Fossil to Professor Juniper and Fennel prior to Archeops In The Modern World!. They successfully resurrected a female from the Fossil using 's dream energy. With the help of and his , Archen learned how to fly and then evolved into .
In A Restoration Confrontation! Part 1, stole a Cover Fossil from Ferris. Dr. Zager revived it into a as part of a plot to lead the team to a time gate beneath Twist Mountain, but the Tirtouga subsequently escaped, evolved into , and returned to the past through the time gate in the next episode.

===Pokémon Origins===
The Dome and Helix Fossils were seen briefly in File 2: Cubone, being hogged by a whom encountered on Mt. Moon.
In File 3: Giovanni, Red was seen using a in his battle against Giovanni, presumably revived from a Dome Fossil. Since Red is mentioned to have caught all 150 Generation I Pokémon (excluding ) by the time of File 4: Charizard, it means that he has also obtained the other Kanto Fossil Pokémon, presumably also revived from Fossils. As was mentioned to have collected 148 Pokémon, it is likely that he had also collected all Kanto Fossil Pokémon.
==In the manga==
===Pokémon Adventures===
In the Pokémon Adventures manga, Lance and Brock both have Fossil Pokémon, just as in the games. Misty also temporarily has an , but she gives this to . In addition, uses Blaine's laboratory to revive an Aerodactyl. In Hoenn, fights a revived and an at Professor Cozmo's laboratory in Fallarbor Town. In Sinnoh, Roark has a like in the games, and his father a Shieldon, which he later gives to . In Unova, N had an , which he released, and has a Carracosta, which was owned by Marshal as a . also has a . In Kalos, Grant has an and a . In Galar, Marvin obtained a after saving it from several Macro Cosmos employees.
==In the TCG==
Fossils are included as cards in the Pokémon Trading Card Game. They are s, and when the Trainer card type was split into multiple subtypes in , cards depicting Fossils usually wound up as s. The first of these cards was released in the expansion, befitting its theme. Their primary role is putting Fossil Pokémon into play, which normally cannot enter play without a Fossil card of some kind due to their unique mechanics. As such, Fossils are released in the expansions as the Pokémon that are revived from them. 
When cards reference cards depicting Fossils, they use the phrase, "Item card that has 'Fossil' in its name", or variations of that. Notably, this means such effects exclude Old Amber cards. However, it is more common for cards to check for exact card names than the phrase "Fossil".
Sometimes cards reference Fossil Pokémon in a similar manner, using phrases that refer to the cards that they evolve from. These include "Pokémon that evolve from an Item card that has "Fossil" in its name", "Pokémon that evolve from Unidentified Fossil", or "card that evolves from Mysterious Fossil", among others. The broadest of these, ones that only call out Fossils in general, exclude that evolve from Old Amber cards. Still, cards more commonly check for the exact card name of Pokémon than for evolutionary lines like this. 
 is a special stage used for Fossil Pokémon in the Black & White Series and the XY Series, starting in . They have unique mechanics separate from the normal way Fossil Pokémon are depicted. However, this change was only implemented temporarily. The Sun & Moon Series reverted back to the normal way Fossil Pokémon are depicted, starting in The period where Fossil Pokémon had the this stage was able to include Aerodactyl when referring to Fossil Pokémon broadly by checking for stage.
===Fossil Trainer card===
Most cards depicting Fossils are Fossil Trainer cards, cards which start as Trainer/Item cards while not in play, but then are played as . The name has not changed since the introduction of the Item subtype. They are non- cards printed with values, and use that HP value while in play. While in play, they have an of . They were introduced in the expansion. They are usually bad Pokémon though, as they do not have s and are unable to retreat (lacking a entirely). Note that the lack of attacks does not preclude them being granted access to attacks, an uncommon but entirely possible occurrence due to s. Additionally, since they are not Pokémon while not in play, cards that search for Pokémon from a cannot retrieve a Fossil Trainer card. Searches for Trainer or Item cards do work, but those effects are less common and weaker than Pokémon search. 
The rules for if a Fossil Trainer card can be put into play while setting up to play has varied as the rules have changed overtime:
*The original Fossil FAQ allowed it, only for a subsequent rule to disallow it on the basis of the card being a Trainer while it is in a hand.Compendium
*In the EX Series starting from , this was changed to fully allow putting Fossil Trainer cards into play while setting up to play.Compendium EX
*Starting with in the Sun & Moon Series, this was fully repealed. There is no longer a window to play Fossil Trainer cards without them being a Trainer card.Ultra Prism rulebook
When players were allowed to do this, it was because the Fossil Trainer card functionally acted as a Basic Pokémon while setting up to play. This means that players were not allowed to take a mulligan when they had a hand that only has Fossil Trainer cards. Even with this in mind, Fossil Trainer cards are not "Basic Pokémon" and decks require a minimum of one Basic Pokémon in them to be legal for play. Also note that this allowance was never afforded to any of the other Trainer cards that are played as Pokémon..
When this permission was allowed, there is an extra incongruity to remember exclusive to the Diamond and Pearl Series and the HeartGold & SoulSilver Series. In those rules, Trainer cards could not be played on the first turn of the player going first, including Fossil Trainer cards that were allowed to be put into play before the first turn of the game.
Fossil Trainer cards have some upsides. A player is allowed to discard a Fossil Trainer card from play at any time, which is not considered Knocking Out a Pokémon. Also, most but not all Fossil Trainer cards have an immunity to s. Fossil Trainer Cards can have or as well. Lacking a Retreat Cost also offers an interesting advantage, as a null Retreat Cost cannot be increased.
Whether or not Knocking Out a Fossil Trainer card allows the opponent to take a varies by the card, with cards of the EX Series or older not providing Prize cards while cards of the Diamond and Pearl Series or newer providing Prize cards equivalent to normal Pokémon cards. 
The primary purpose of a Fossil Trainer card is that they can evolve into Fossil Pokémon. Even the lowest form of a Fossil Pokémon's evolution chain is a , so those cards have to enter play by evolving from a Fossil Trainer card. The Fossil Trainer card that a Fossil Pokémon evolves from varies by which set the Fossil Pokémon is in, as new Fossil Trainer cards are released in new expansions. In some cases, multiple different Evolution chains start from a singular Fossil Trainer card. In other cases, each evolution chain has a dedicated Fossil Trainer card, having the name of the Fossil the species is revived from.
The first Fossil Trainer card was , which could be evolved into any of the three Generation I Fossil Pokémon: , , and . It has only 10 HP, lower than even . It does match the HP of , another Trainer card played as a Pokémon. This card continued to see printings into the EX Series, although increased the HP Mysterious Fossil has to 50. It does not allow opponents to take Prize cards when it is Knocked Out. It also has the customary immunity to Special Conditions.
The EX Series indroduced two new Fossil Pokémon, and . These species received dedicated Fossil Trainer cards for their line starting with the expansion: the and the , respectively. These cards included beneficial Poké-Bodies, making these cards slightly stronger. They have 40 HP. Again, these cards do not allow opponents to take Prize cards when they are Knocked Out, and they cannot be affected by Special Conditions. This would herald the end of shared Fossil Trainer cards for a while, as the Diamond and Pearl Series followed this series lead and introduced more individual Fossil cards.
The Diamond & Pearl Series added the and Fossil cards, for the new species of and . It then went the extra mile and added individual , , and cards for its printings of Kabuto, Omanyte, and Aerodactyl. All of these cards included included Poké-Bodies, and were printed with 50 HP. The Root and Claw Fossil cards were also reprinted, keeping their older 40 HP. However, starting with , the expansion which added the Skull and Armor Fossils, Knocking Out a Fossil Trainer card is equivalent to Knocking Out a Pokémon. Thus opponent take a Prize card after doing so. This change even applied to the Root and Claw Fossil reprints, and continues to be true today. However, these cards still cannot be affected by Special Conditions.
No Fossil Trainer cards would be printed for nine years, as their last printing was in . Fossils and Fossil Pokémon skipped the HeartGold & SoulSilver series wholesale, and the Black & White Series and XY Series experimented with a different set of mechanics for putting Fossil Pokémon into play. 
, of the Sun & Moon Series, saw the return of a shared Trainer card which could evolve into any Fossil Pokémon released during the Sun & Moon Series. The card is , and this card broke the long standing tradition of being unable to be affected by s. It has 60 HP, indicating a gradual increase with each series.
