Shelmite is a Pokemon that is resurrected from a seaside fossil. It is a poison and rock type, and it's PokeDex entry says, "It inhabits curtain types of shells found along the beaches in the Aegean region. When threatened it sprays a fatal poison at the enemy, so people are always cautious around it." I'm still working on it's evolution, so look out for that.
