The Mastodon Dinozord was piloted by the Black Ranger.

It could fire frigid blasts of cold air & mist at enemies, temporarily freezing them. Its hiding place was in the deep Arctic. Its body formed the back and arms of the Megazord and Dragonzord Battle Mode. The head could be utilized as a shield.

After Lord Zedd stripped the Zords of their power and sank them into lava under the Earth, Zordon and Alpha were able to use its remains to create the Lion Thunderzord.
