Dinosaurs

"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.""

Dinosaurs are a diverse group of prehistoric reptilian animals all groups of which are believed to be extinct until the late 20th century.

History
In the Prehistoric Era stranded time-travelling Ray Palmer was forced to survive in the world dominated by dinosaurs, encountering at least Tyrannosaurus Rex until he was rescued by Nate Heywood and Mick Rory.

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 full-sized sculptures of the dinosaurs located at the front of it.

Trivia

 * So far dinosaurs were only confirmed to exist on Earth One in Shared multiverse.

Behind-the-scenes

 * Ironically enough dinosaurs on Earth One were first seen appearing on Constantine, a show which also establishes existence of God in the Shared multiverse, those establishing that both evolutionary theory and Deism are right in their own sense in the multiverse.
