The series was first announced in December 2020 with a trailer shown during the Game Awards, alongside a large voice cast reveal.

Series co-creator Jeremy Stieglitz said development began in 2019 when he and co-creator Jesse Rapczak worked out a budget and outline for the show, but production was delayed by the COVID-19 pandemic.

The creative team deliberately chose hand-drawn 2D animation instead of 3D game-style models, believing hand-drawn animation ages better and wanting to visually distinguish the series from the video game.

Cultural consultants were brought in for episodes dealing with indigenous cultures, helping with plot aspects, flashbacks, and language related to those cultures.

Vin Diesel joined the cast and also serves as an executive producer alongside Gerard Butler and Russell Crowe, who came on board as executive producers following the December 2022 trailer.

Monica Bellucci and Dee Bradley Baker were added to the voice cast in June 2022 when the series entered post-production, with Baker providing vocalizations for various creatures including Helena's dodo and Parasaurolophus companions.

The first six episodes were released as a surprise drop on Paramount+ on March 21, 2024, after being delayed from an originally planned 2022 release, and multiple critics noted the lack of marketing around this sudden release.

Critics frequently compared the series to other works such as Jurassic Park, Primal, Predators, and Turok: Dinosaur Hunter, with several praising its use of dinosaurs and visual storytelling despite a mixed overall reception.
