All decisions in life should be like helix fossil/ dome fossil. You can't continue without taking one of them.— Michael (@lendafender) February 26, 2010
Where to Find Fossils?
Players will encounter Mt. Moon as their first cave after defeating Brock, the Rock-type Gym Leader in Pewter City.
As players make their way through the cave, they will eventually come across a scientist blocking the path. He will challenge the player to a battle after claiming two unique fossils for himself, sending out a Voltorb and a Magnemite. Once the player defeats the scientist, he will reluctantly offer either a Dome or Helix Fossil to the player, allowing them to choose which they would prefer.
Dome vs. Helix Fossil
Players can approach the fossil of their choice to collect it, but it’s important to note that once the choice is made, players will not be able to obtain the other fossil again as they venture throughout the game.
