The Jurassic League presents a prehistoric version of Earth from an alternate reality where the heroes and villains of DC are anthropomorphic dinosaurs.

It's been an absolute pleasure to join Juan Gedeon in creating a new world for DC, complete with dinos, cavemen, and extinction level events".

[5] For example, he and Johnson decided to turn Wonder Woman into a Triceratops, as they considered it to have an "athletic" physique that would fit with Wonder Woman's; in Superman's case, they chose a Brachiosaurus, as it was a herbivore that seemed harmless, but solid and strong at the same time, akin to the hero's image; and for Batman, the duo intended to change him into a "carnivorous dino", and Allosaurus felt right as it had horns that resembled Batman's cowl ears.

[6] The Jurassic League was co-written by Daniel Warren Johnson and Juan Gedeon,[7][8] the latter of whom also handled the interior artwork for the comic book,[9] while the former designed the front covers for all its six issues.

[12] The Jurassic League appear in Batman: The Brave and the Bold issue #14, released on June 25, 2024, written by Mark Russell and with Jon Mikel handling the artwork.
