It seems to be dinosaur month here at Xeno, so I'll just go along with it. Here are two clips from fun Tsuburaya shows. The first one is from Aizenborg and features the jumbo hero from the later episodes. Most of us know this show from the compilation movie ATTACK OF THE SUPER MONSTERS, it's a shame they never used any more of the footage.
And the second bit is from Kyoru Sentai Koseidon, featuring the masked dinosaur fighting hero Koseider. He doesn't grow to giant size, but this is the best of all three of TPS dinosaur shows.
