The Turtles receive a blast from the past when Dinosaurs invade the Big Apple. The TMNT attempt to coral the beasts, and more or less succeed.
Befriending a young diplodocus they dub "Dippy", the Turtles trace the invading dinos to their source, and they are shocked by what they find there: a "lost world", hidden deep beneath the earth's core, where the ferocious creatures of yesterday still thrive. The TMNT find out that the reason for the Dinosaur's continued preservation is the radiation sent off by a mystical energy crystal.
Before the turtles can relax and explore this "new world", they find out Shredder and Krang are after the crystal, intending to use it in another diabolical scheme to re-power the Technodrome. The Turtles join forces with Dippy to stop the villains, they are able to drive Shredder back at first, but their actions provoke Krang to take a trip to the savage land himself.
Upon arriving, he builds a hi-tech titanium plated battle fortress, from where he can harness the crystal's powerful energies and channel them into the Technodrome directly from this base. Shredder eventually manages to outwit the TMNT, and succeeds in obtaining the crystal.
But things go awry when Shredder accidentally drops the crystal, damaging it, without the crystal, (the source of their life-energy), Dippy and his fellow dinos begin to slowly die.
The TMNT attempt to penetrate Krang's fortress with Dippy's help, but his strength alone isn't enough, Just when the green machine think all is lost, Dippy calls on other dinosaurs to assist him, with their combined efforts, the dinos are able to break into Krang's fortress, and a fierce battle ensues...
