Dinosaur King

The Search for the Last Cosmos Stone is the 28th episode of Mesozoic Meltdown and the 77th episode of Dinosaur King overall. It is the 3rd episode of the 5-part Season 2 Finale arc, the 1st of the 2-part Black Cosmos Stone sub-arc.


Confronted with Spectre's Apatosaurus, Brontikens, the D-Team futily tries to fight the Space Pirates as they search for the last Cosmos Stone. The Cosmos Stone Detector pinpoints the Stone as being inside the volcano, so Brontikens rams it before hitting it with Spectral Destroy, but this accidentally causes the volcano to erupt, debris destroying the Detector (again). While the D-Team flees to the Backlander, Helga is forced to go down and manually extract the Alpha Gang, who stay long enough to see the Black Cosmos Stone flying from the volcano and being swallowed by a woolly mammoth. On the Space Pirate's ship, Spectre yells at his Pirates and orders Dr. Ancient to fix the Detector, but Dr. Ancient shows Spectre that bringing the Cosmos Stones together will release enough energy to destroy the Universe ten times over (a number on the screen shows over 666 quadrillion of something). Spectre is unfazed and still insists of finding the seventh Cosmos Stone; Seth watches unseen.

On the Backlander, when Dr. Z tells that a mammoth ate the Cosmos Stone, Max remembers that he and his dad had excavated a mammoth buried under volcanic ash 3 years earlier on summer vacation, and Jonathan confirms the location of the two sites—it was the same animal. Drs. Ancient and Cretacia have refused to fix the Detector, the parents hoping the D-Team can succeed. Arriving over the dig site, Jonathan causes a minor tremor to make the past Max and Dr. Taylor leave, just as Max remembered happening before. As they try digging up the mammoth, the Space Pirate Ship arrive, Gabbro throwing an electrified net, so Jonathan teleports both them and the mammoth fossil to the Backlander, where they retrieve the Black Cosmos Stone. Spectre contacts them and tells them that he will trade their parents for the last Cosmos Stone. Dr. Z refuses, wanting to use the Stone's power to become the Dinosaur King, of course rescuing everyone from Spectre with his first act as Dinosaur King, but Max snatches the Stone and decides to do the trade…with at catch.

When both parties show up to make the trade, they argue who goes first before agreeing to and beaming their respective bartering items to each other at the same time, a ring of stasis pods with the D-Team's parents and the table with the Black Cosmos Stone. However, as the pods open, their parents morph into Gel Jarks, and the kids are seized. However, Seth shows up and notes the Cosmos Stone as a fake, too, Shear shattering it on the ground; Spectre demands the real Cosmos Stone and for Seth to bring the D-Team aboard. Seth instead sends the Gel Jarks to the Backlander, convincing Jonathan to beam them aboard with the D-Team, another Gel Jark wheeling a case with the other 6 Cosmos Stones over as well. Realizing he's been betrayed, Spectre orders his Space Pirates to attack, but Seth summons a Cryolophosaurus. On the Backlander, the Gel Jarks have grabbed everyone on the bridge; in the kitchen, Helga fights off two Gel Jarks, realizing that they melt when they touch the salt she was cooking with. Down in the battle, Seth admits to Spectre he wanted the Cosmos Stones to himself all along, his Cryolophosaurus easily besting the Space Pirates' dinosaurs and freezing them with Blizzard Smash; he teleports to the Backlander.

With the ship in the time vortex, Seth searches for the Black Cosmos Stone while the Gel Jarks hold the D-Teams' Dino Bracers. Seth finds the Stone, but the Space Pirate Ship crashes into the Backlander, knocking the prisoners free. Helga arrives and starts melting the Gel Jarks with spoonfuls of salt, Rod and Laura and the Alpha Trio helping, while Max grabs his Dino Bracer and races off. He finds Seth with all the Cosmos Stones, who summons Cryolophosaurus; Max summons Chomp and tells him to prepare for the battle of their lives…


D-Team vs. Spectral Space Pirates (continued)[]

The D-Team is facing the newly summoned permanently Spectral Armored Brontikens.

Paris charges and rams into Brontikens, but is knocked away. Ace rushes and bites him, but is bitten back and pulled off and thrown into the ground. Chomp tries attacking, but is blocked and attacked by Gigas, Armatus, and Maximus.

On Spectre's orders, Brontikens charges through the Chomp/Gigas, Maximus/Paris, and Armatus/Ace fights and rams a hole into the volcano trying to reach the Black Cosmos Stone. Chomp breaks off from fighting Gigas and tries to attack Brontikens, but he rears and kicks Chomp away. Ace and Paris try to help, but Armatus and Maximus stop them.

The Alpha Gang teleports in, but flee when Brontikens tries stepping on them. Then Brontikens hits the volcano with Spectral Destroy, but the blast causes the volcano to erupt. Both the D-Team and Space Pirates recall their dinosaurs and flee.

No Result

Seth/Cryolophosaurus vs. Spectral Space Pirates[]

Gabbro flies up to the traitor Seth and summons Gigas, but Seth summons Cryolophosaurus, who jumps over Gigas and then knocks his legs out from under him from behind. Foolscap and Shear then summon Armatus and Maximus, who charge, and Cryolophosaurus rushes up to battle them.

After cutting back to the fight, Cryolophosaurus leaps back; Gigas and Armatus try to ram it between them, but Cryolophosaurus jumps away and the two smash their heads against each other. Maximus tries charging Cryolophosaurus, but it knocks him into the air and rams him several times with a midair zigzag maneuver before kicking him into the ground.

Spectre's hologram tries convincing Seth to stop, but he's made up his mind. The Space Pirates activate their respective Spectral Moves, and their dinosaurs charge Cryolophosaurus, but Seth has it use Blizzard Smash to freeze them in a glacier. He recalls Cryolophosaurus and teleports to the Backlander.

Seth/Cryolophosaurus win

New Cards[]


-Spectre: "If you plan on stopping me from getting that last Cosmos Stone, it's going to take a lot more than just you little tykes."
(Alpha Gang teleports down)
-Dr. Z: "Careful what you wish for! Now you have the Alpha Gang to deal with."
-Spectre: "Wish? If I were going to wish for something, then"—(chef's kiss)—"it'd be those darling eyebrows."
-Dr. Z (angrily): "My eyebrows aren't 'darling'! They're thick and wiry like steel wool!…But thanks for noticing."

(the Gel Jarks Seth claimed were harmless are capturing everyone aboard the Backlander)
-Dr. Z: "Ah! Why do we keep trusting Seth?"

(the Space Pirates' dinosaurs have been frozen by Cryolophosaurus' Blizzard Smash)
-Gabbro: "Well on the plus side, if anyone's in the mood for snow cones we got plenty of ice."


  • This episode has the longest English title by words, at seven, though There's No Business Like Shogun Business has a longer English title by characters (including spaces), at 40 vs. 36, despite only having six words.
  • The numbers on Dr. Ancient's Cosmos Stone energy output projection are clearly random, as the digits jump up and down while the number simply gets longer, even resulting in the actual value getting smaller at times if examined frame by frame, and starting with a zero at times (which should simply go undisplayed if accurate).
  • After just having a pair of episodes show what happens if the Backlander leaves with history altered, they simply leave the Stone Age volcano erupting and expect nothing bad to happen in time. Possibly they thought it was too small of a change, and it does turn out to have no harmful consequences, but they don't even worry time could go wrong again.
  • Zoe claims that the crust of the Earth had moved "so much" since the Stone Age, but the Earth's tectonic plates would only move significantly over millions of years, not the mere thousands of years since the Stone Age.
  • The map on the monitor also showed numerous incorrect continental movements: all the continents splitting at once instead of becoming a northern and southern supercontinent first; India always being connected to Asia instead of crashing separately later; Australia and Antarctica (the latter not even being shown) always being separate from the rest of the continents; etc.
  • It's odd that this episode features time travel being part of established past events (the tremor scaring Max and Dr. Taylor away from the mammoth fossils) when just last episode the plot centered around time travel messing with the timeline (insects and plants ruling the world). These are two different takes on the possible mechanics of time travel that are typically left separate in fiction, only one being the case per story.
