Kyōryū Sentai Zyuranger

From Wiki- Five young warriors from an ancient civilization of dinosaur-evolved humans (恐竜人類, Kyōryū Jinrui) are awakened during the present day after 170 million years of suspended animation when their sworn enemy, Bandora the Witch, is inadvertently released from her magical container on Planet Nemesis by two astronauts. The five warriors, the Zyurangers, must summon the power of mechanical-looking deities known as Guardian Beasts, each modeled after a different prehistoric beast, in order to protect mankind from Bandora's evil forces. A sixth warrior, Burai the Dragon Ranger, later becomes involved with the conflict between the Zyurangers and Bandora's forces.  Now back to me!

Thanks to Tubi, I watched the first two episodes of this show the other day.  It has been over eight years since the DVD release here in the States, but I had others to watch before this.  I really enjoyed the what I saw, and got a great price on the DVD set.  I never would have thought Power Rangers would be 30+ years old now, but this was a unique show for US kids, and it isn't surprising that it was a hit.  I still wish the scripts for the US show were better, though.  I will review the series as I watch it, here and there.
