Omanyte and Omastar for example became too big and slow for hunting
>A prehistoric Pokémon that died out when its heavy shell made it impossible to catch prey. Some extinctions follow the meteor-theory, aerodactyl for example
>A widely accepted theory is that it went extinct due to a large meteor impact. Cradily and Liliep, I imagine, became extinct because the oceans got too cold for them, or not at all
>It lives in the shallows of warm seas. Anorith either became extinct because of that, too, or evolved (actual biological evolution, not the metamorphosis thats called "evolution" in the franchise) to birds or other land-dwellers.
>Over time, its eight feet transformed into wings. >It went ashore after evolving.Since Cranidos and Rampardos lived around the same time as Aerodactyl, I guess they died because of said meteor, too.
>It used its skillful headbutts to combat Aerodactyl. Same with Shieldon and Bastiodon
>It lived in the same environments as Rampardos. Their fossils have been found together—seemingly from after they'd fought to the finish. Tirtouga and Carracosta have the same reasons as Liliep and Cradily
>it lived in warm seas approximately a hundred million years ago. Archen and Archeops died out due to stronger competition, I guess. They couldn't really fly, so foes who could had an advantage.
>Archen itself could not actually fly but moved by hopping from treetop to treetop. >It runs better than it flies.Tyrunt and Amaura... Eh, same as Aerodactyl.
