Tommy's Black Box  which contains his Dino Gem
Destroyed Gem
New footage of the Terrorsaurus

Zeo Ranger 5 
The Mighty Morphin White Ranger 

Dragon Dagger   
Green Ranger 
This is likely new
I believe this is new

New footage of Black's Super Dino Mode 
The white gem-like crystal that held the captured Rangers' powers is I believe always in new footage since I think it was an item that was exclusive to Power Rangers.
Once you see Terrorsaurus again is when it goes back to Sentai footage since at that point in the episode he will be a Giant.

NOTE: All Terrorsaurus 2 Sentai footage comes from Abaranger 40.
