Edaphosaurus (meaning "pavement lizard") is an extinct genus of edaphosaurid synapsids that lived in North America and Europe during the Late Carboniferous and Early Permian periods.
Edaphosaurus is featured in in Jurassic World: Alive as an Epic Fierce creature. It was erroneously portrayed as a carnivore due to it sharing its animations with Dimetrodon and Ophiacodon, although this was fixed in a later update.

Edaphosaurus is an obtainable creature in Jurassic World: The Game. However despite being a herbivore in real life, it is erroneously classified as a carnivore due to sharing the Dimetrodon model.
Behind the scenes
The Edaphosaurus was one of the animals seen in Jim Martin's storyboards for Jurassic World that did not appear in the final film. It was seen with a crested hadrosaur (likely Corythosaurus) and an unidentifiable ornithopod gathered around an early design of the Jurassic World Monorail.
If this pelycosaur had made it to the final cut of the film, it would have not only been the first synapsid to be featured in the films, but also the first prehistoric animal that lived before the dinosaurs. This spot will eventually be filled by Dimetrodon as a statue in Jurassic World: Fallen Kingdom, and officially in Jurassic World Dominion with Lystrosaurus.
