The Dino Gems were created by the Morphin Masters using the Morphin Grid and sent out into the universe to fight evil. Sometime later, they ended up on the meteorite that crashed into Earth and wiped out the dinosaurs. They were later discovered by Tommy Oliver, who hid them, knowing the risks of what would happen should they fall into the wrong hands.

He also solicited Hayley Ziktor to create four Dino Morphers, which could harness the powers of the Dino Gems, allowing the beneficiaries to become Power Rangers. After Conner, Ethan, and Kira bonded with the red, blue, and yellow Dino Gems, they were given three of the Morphers. Mesogog discovered the Black Dino Gem encased in amber, and captured Dr. Oliver. The good doctor managed to escape, with the Black Gem's powers bonding to him and allowing him use of the Black Morpher. Mesogog also had the White Gem, and secretly created his own Ranger Morpher to utilize its powers; this later came into the possession of Trent Mercer.

The Dino Gems were later drained of their power when the Rangers used it to destroy Mesogog for good, likely negating the Rangers' special abilities as well. The gems were eventually restored presumably by Tommy and Billy Cranston.

Eventually, Tommy had incorporated his Black Dino Gem into his Master Morpher, allowing him to morph into his Black Dino Ranger form at any time.
