Technically a good number of the "Dino" Charge Rangers and zords weren't based on actual Dinosaurs. Hell, the original MMPRs are consistently referred to as having powers of the dinosaurs, but only two of the Rangers are based on dinosaurs.

Three. Pteradactyl, Triceratops, and T-Rex. Only two were not Dino's, Mastodon and Sabertooth Tiger.

Actually, while this is not commonly known, pterodactyls aren't actually considered "dinosaurs".
They are pretty simplistic, but the way they combine isn't condusive to the transition to zordbuilder. That said, I was thinking about it, and they could probably pull another Dino Charge by having the zordbuilder stuff built into the lion zord rather than the limbs themselves. That way the limbs can attach to the pieces of the lion zord, which then in-turn connect to the main body of the lion via zordbuilder ports.

On a side note, is it Kyuranger or Kyuuranger? I've been assuming the first is correct, but I'm seeing the second spelling pop up a lot too...

EH?! Then what are they considered?!

They're "pterosaurs".

How many of the Zodiarts aren't in the Zodiac again?

red, black, orange, gold, and depending on who you ask silver is also some time a part of the Zodiac. Pink, Blue, Green and yellow are not a part of the Zodiac. The reason silver is considered by some is because the Ophiuchus' lowest star falls between Sagittarius and scorpius

also i see what you did there and that answer is 17

Power Rangers Zodiac would work. Or Power Rangers Solar Squad/Solar Force.

But the best name is Power Rangers Galaxy Quest.
