Scorched Feathers, Octillery, Beartic, Walrein, and Malamar aren't starters. But if you wanna play that game, then...
Sauropod (Meganium, Aurorus), Frog (Poliwag line, Froakie line, Toxicroak), Pachycephalosaurus (Breloom, Rampardos, Haxorus (50/50)), Crocodile (Totodile line, Sandile line), Dragon (Charizard, dragonite, Salamence, Druddigon, Palkia, Zekrom, etc), Monkey (Chimchar line, elemental monkeys, aipom), Aquatic turtles (squirtle line, Carracosta), so on so forth. Basically my point is, just because they're the same animal doesnt mean that there can't be more like it, or else Pikachu, Marril, and a few others wouldnt exist simply because Rattata is a mouse and so are they.
