Official DescriptionEdit

We could blame everything that happened on Marco. He was the one who heard about the downed submarine. He was the one who thought we should check it out. And everyone knows that if Marco's up to a challenge, I'm definitely there.

Everything was going fine. Until the explosion. An explosion that blows us millions of years back in time. Back to the age of dinosaurs. Now Tobias, Cassie, Marco, Ax, Jake and I are fighting for our lives with every step we take. But that's not our biggest problem. Our biggest problem is we have no idea how to get back to our own time ...[1]

  • Note: at the end, since it appears that the collapse of a Sario Rip negates any physical consequences that took place for those involved in the rip, the Animorphs lost the dinosaur morphs they acquired while they were in the past and can't morph into them anymore upon returning to the present.


  • All six megamorphs 2 time of dinosaurs covers

    All six Megamorphs 2 covers, one for each character mirrored in the corresponding inside cover. Note that the covers of the actual books say IN THE TIME OF DINOSAURS in the middle, not <NO ONE KNOWS WHO WE ARE> which is what is shown in the above images downloaded from the official web site.

    Megamorphs #2 was originally a big summer event for Animorphs. There was a lot of advertising put into it months before its release, with posters and special book stands for book sales that were given out. It also stands as the only Megamorph to have seven versions of its cover, each with a different color front, which reflected to a different Animorph in the inside cover: Jake, Rachel, Marco, Cassie, Tobias, and Ax. The 7th inside cover consisted of all of their covers combined in a 2 by 3 grid.
  • Ax and Tobias are the only two that don't have a secondary morph in the inside covers because their natural bodies are actually their battle 'morphs'.
  • The Megamorphs aren't the only books in the series that provide narration from more than one Animorph at a time. In Animorphs #19: The Departure, Jake provided narration for at least one chapter when Cassie couldn't. In #54: The Beginning, the book itself acted as a Megamorph by giving narration from most of the Animorphs one last time before the series ended. Lastly, The Hork-Bajir Chronicles, also provided a narration from both Aldrea and the Yeerk Esplin (Later Visser Three)[2]
