"Once there was a little dinosaur called a Maiasaur, who lived with his mother. One day, he told his mother, "I wish I were special like the other dinosaurs. If I were a T. rex, I could chomp with my ferocious teeth!" "But if you were a T. rex," said his mother, "how would you hug me with your tiny little arms?" "I wish I were an Apatosaurus," said the little dinosaur, "so with my long neck I could see high above the treetops." "But if you were an Apatosaurus," said his mother, "how would you hear me in the treetops when I told you I love you? What makes you so special, little Maiasaur?" said his mother. "Is it your ferocious teeth or long neck or pointy beak? What makes you special is out of all of the different dinosaurs in the big, wide world, you have the mother who is just right for you and who will always love you."
The Runaway Dinosaur book[src]

Dinosaurs are a diverse group of reptilian animals, most of which are believed to have gone extinct by the end of the Cretaceous period and the time of humans. Despite this, some dinosaurs interacted with humans due to time travel.[1]


In what would eventually become known as South Dakota, 69,997,983 BC (during the Cretaceous period), the time-stranded Ray Palmer was forced to survive in the world dominated by dinosaurs, encountering at least one female Tyrannosaurus rex (which he nicknamed Gertrude) and possibly a male as well. Ray was confronted by Gertrude before he was rescued by Nate Heywood and Mick Rory.[1]

When the Waverider crash-landed back in the same geological time period, Ray led Nate and Amaya Jiwe to retrieve a component of the ship, which had ironically ended up in Gertrude's nest. When Gertrude came across them later, Amaya used the Anansi Totem to use the spirit of a T. rex to communicate with the female, resulting in Gertrude leaving them in peace. [2]

At some point in time, a few fossil skeletons of dinosaurs were dug up and placed in Fernbank Museum of Natural History in Atlanta, which also had at least two life-sized skeleton sculptures of the dinosaurs located at the front of it.[3] Aside from museums, dinosaurs were also immortalized in literature, with Barry Allen's favorite book as a kid being The Runaway Dinosaur.[4] This book was also popular on Earth-38, it was transalted to Russian and distributed in Kaznia, where the Red Daughter read it.[5]

Dinosaurs from the Cretaceous period appeared en masse in 2017's Los Angeles after the actions of the Legends created a time storm and "broke time", however they were relatively quickly captured by Rip Hunter's Time Bureau and sent back to their time.[6][7] Later on, Ray, Nate, and Jax discussed the idea of having a small dinosaur as a pat on the Waverider, musing over such species as Aquilops, Compsognathus and Oviraptor.[8]

Behind the scenes

  • Dinosaurs are a diverse group of animals of the clade Dinosauria (sub-group of clade Dinosauromorpha, class Reptilia), that first appeared during the Triassic period. Today, only theropoda, the saurischian dinosaur group, remains, represented by Aves - birds.
  • Although a number of deistic religions in real world deny the existence of dinosaurs, ironically enough dinosaurs on Earth-1 were first seen depicted in Constantine​​​, a show which also established the existence of God in the Arrowverse, implying that both deistic and evolutionary assumptions regarding the world's prehistory are correct on some level in the multiverse.[3]
