>>10959799>may get fossilizers but idk their robot modes arent very satisfying to meyeah, some of them are weird (though in Transmutate's case, the weirdness works and it's possible to arrange her limbs to make her look close to the show), and I get that the partsforming bit doesn't click with everyone, but I still recommend any of the three (four, counting Spindle) bots that use the Paleotrex mold, at least.
Also, I'll again vouch for Vertebreak and Dracodon - they're skele-dinos, but aren't 'Fossilizers' in that they don't partsform. They're just cool little Dracorexes that are among the best Core class 'bots they've created to date.
