Aldo said it best. Yes the entire Super Sentai meta-series where backstories conflict one another. The best way to explain it is as was said once somewhere, I forget. Continuity applies where it does and doesn't where it isn't convenient.

This might help. Earth is a BIG place. You don't need to worry why various factions haven't encountered each other. So far I don't see anything in Kyoryuger to directly counter other shows. If anything the big issue is the extinction of dinosaurs which was covered by several other shows in a different way.

However, none of those affect the Sentai Legacy really, so if it makes you feel better. Think of them as retcons. :)
