If you've played Pokémon Allow's Become, Pikachu! or Eevee! for more a couple of hours, you may have come across a choice that'll experience familiar to any veterans of the original games: the decision between the Dome and Helix fossils.

You run into the option once you lot reach the end of Mt. Moon, which you'll get exercise after defeating your first Gym Leader in Pewter Metropolis, and while itispossible to go both fossils by the end of the game y'all won't go the chance until much, much subsequently. Then y'all'll want to make the right choice first time around.

So, why is it such a big choice?

When you commencement pick upward either fossil, it'south not articulate what information technology'south good for. Only later in the game you'll detect Cinnabar Island, and once there you tin convert your fossil into ane of two Fossil Pokémon. Which fossil you have determines which Pokémon y'all get, so really you lot're deciding between the 2 Pokémon.

Dome Fossil: Kabuto and Kabutops

Choose the Dome fossil and you'll later get to convert information technology to Kabuto, a Rock/H2o-type Pokémon that evolves into the pretty snazzy looking Kabutops at level 40. It also has the chance to learn some Grass, Steel, Dark, and Ground-type moves, which makes for a pretty diverse ready, and can even option up a few Ice, Poison and Problems-type moves from TMs.

Here are the base stats y'all tin can expect: 60 HP, 115 Attack, 105 Defense, 65 Sp. Attack, 70 Sp. Defence, 80 Speed

Helix Fossil: Omanyte and Omastar

Meanwhile, cull the Helix Fossil and yous'll get Omanyte, which is too Rock/Water, and as well evolves at level 40 - into Omastar.

Omanyte and Omastar are much more focussed on those core types though, only getting a single move each from Ground and Night outside Stone/Water/Normal, though can at least become some Water ice, Toxicant and Steel-type moves from TMs.

Here are the base of operations stats, which are as well a scrap dissimilar: 70 HP, 60 Assault, 125 Defense, 115 Sp. Attack, seventy Sp. Defence, 55 Speed

How to convert the fossils into Pokémon

Once you lot have your fossil of choice, you lot'll actually have to hang onto it for quite a while. It won't do much until y'all get to the Pokémon Lab on Cinnabar Island, fairly late in the game.

Once you're in that location it'southward very simple though. In the back right of the edifice, you lot'll run into a scientist adjacent to a Poké Brawl machine. He's able to resurrect your fossil and turn it into your Pokémon, at which points it'due south yours to railroad train.

How to get both fossils

We mentioned before that it is possible to get both fossils, if you don't mind waiting a while. That's because correct at the end of the game you can detect both of them in the Cerulean Cave, near Cerulean City.

You might recognise the proper name - this is where yous'll also observe Mewtwo, but he's not the only thing of value in the cave. Head to the superlative floor (2F) and you should observe one of the fossils subconscious in front of the large crystals in the center of the flooring - your Pokémon should help yous discover them.

You'll only find one of the 2 at any given time - or the Old Bister, which can also be used on Cinnabar Island, to resurrect Aerodactyl - but one spawns at random each day, and then keep trying and eventually, you should accept all three fossils, and all iii Pokémon.
