Hmmm... Complete lack of dinosaur sentai team members... A witch that lives in Bandora's Palace trying to assemble a mystical space rock... A mysterious armored knight trying to gather strength...

My random guess is that Rita is trying to create a giant wish meteor to wipe out dinosaurs from ever existing, thus fulfilling the wish of her mother Bandora. Gaisorg is actually the embodiment of all the dinosaur Sentai's powers, akin to AkaRed, trying to find a host to wield it's power. This will then lead to the Ryusoulgers showing up with the other dinosaur sentais to beat Rita. (I can also see Team Oddball using Ryusoulger's Power Souls to fight alongside them, that or Marvelous giving them Ranger Keys.) Ultimately though this is all set up for a massive movie crossover between all the dinosaur sentai teams, where they fight all a combined army of all their foes determined to rid the universe of dinosaurs. Made in part so it can used for Power Ranger footage. I can also see the Kyoryuger Brave mecha being used here, too.
