Series developer Zack Stentz pitched the idea for the show to Universal Pictures, with production beginning as early as April 2017; Scott Kreamer later took over Stentz's premise and pilot script in June 2018.

Steven Spielberg insisted the series not be a 'kiddy version' of the Jurassic Park films, wanting the young characters placed in genuinely dangerous scenarios just like in the movies.

Unlike the films, where children are secondary characters rescued by adults, the showrunners deliberately focused on teenagers surviving on their own, inspired by other Spielberg films depicting kids facing danger.

The role of camp counselor Dave was written specifically for Glen Powell, which he said made voicing the character 'easy and fun'.

Crew members rewatched Jurassic World multiple times and created their own map of Isla Nublar to help develop tie-ins between the film and the series.

Production continued during the COVID-19 pandemic, forcing the series crew to work from home.

Writers originally planned for Ben to die shortly after his fall in the season one finale, but these plans were scrapped and the character survived to continue appearing in the series.

Writers initially thought the B.R.A.D. robots were too unrealistic for the show, but changed their minds after watching a Boston Dynamics robotics video and decided to include them in season four.

Composer Leo Birenberg created original music using themes from John Williams' Jurassic Park and Michael Giacchino's Jurassic World scores, and got involved in the project after being recommended by Giacchino, whom he had met while working on Kung Fu Panda: The Paws of Destiny.

The idea of a romance between Kenji and Brooklynn was first proposed and dismissed during the making of season two before being introduced later, as the writers felt it was a natural progression for characters stranded together for six months.

Season two's plot deliberately incorporated big-game hunting as a major theme, inspired by the animal trafficking subplot in Jurassic World: Fallen Kingdom, to teach children that such real-world problems exist.
