Which 2019 Jurassic World short film premiered on FX?

Battle at Big Rock was the 2019 Jurassic World short film that premiered on FX.

Directed by Colin Trevorrow and written by Trevorrow and Emily Carmichael, the short takes place one year after Jurassic World: Fallen Kingdom. It follows a family camping at Big Rock National Park as they encounter a Nasutoceratops family and a hostile Allosaurus.

The film is significant because it shows the franchise's new status quo: dinosaurs are no longer confined to a theme park or a remote island. They are beginning to live alongside humans in the wider world, setting up the premise of Jurassic World Dominion.

Battle at Big Rock was announced on September 10, 2019, and premiered on FX five days later, on September 15. It was then released online. A common mix-up is treating it as a full theatrical feature; it is a short film, running about eight minutes, with a standalone story and only limited links to the main characters.
