Battle At Big Rock: Jurassic World's Two New Dinosaurs Explained

The upcoming Jurassic World short film Battle at Big Rock will introduce two new dinosaurs to the franchise, the Allosaurus and the Nasutoceratops. Neither dinosaur has ever appeared in any Jurassic Park or Jurassic World movie. The short film will be directed by Colin Trevorrow, the director who brought the franchise back into relevance with 2015's Jurassic World. Jurassic World was the fourth installment in the series and the first since Jurassic Park III in 2001. With an astounding worldwide box office gross of $1.6 billion, Jurassic World was a huge critical and commercial success.

Universal Pictures followed up with a sequel in 2018 with Jurassic World: Fallen Kingdom, with J.A. Bayona as the director and Trevorrow credited as a writer. Trevorrow will be back to direct the third film in the series, which is tentatively titled Jurassic World 3 and set for a 2021 release. It was recently confirmed that Trevorrow secretly directed the first live-action short film in the franchise, Jurassic: World: Battle at Big Rock, which will be released on FX on Sunday. The cast includes André Holland, Natalie Martinez, Melody Hurd, and Pierson Salvador. The entire film was shot in five days in Ireland.

The eight-minute short picks up one year after the cliffhanger ending of Fallen Kingdom, which saw all the dinosaurs get set free, forcing humans to coexist with dinosaurs. Battle of Big Rock follows a family of four whose camping trip at Big Rock National Park is interrupted by an encounter with dinosaurs. Trevorrow revealed in an interview with Collider that the events of the film will introduce two new dinosaurs to the franchise, the Allosaurus and the Nasutoceratops. Here's what you need to know about the two newest additions to the series.


A  much smaller relative of the Triceratops, the Nasutoceratops is a somewhat new finding in the paleontology community. Discovered in 2013, this large dinosaur lived in southern Utah during the Cretaceous Period. Unlike the Triceratops, the Nasutoceratops' horns grow out to the side, like a bull. Trevorrow has likened the dinosaur to a "Texas Longhorn". Since the Nasutoceratops was a peaceful herbivore, its unlikely to pose a major threat to the family featured in the short film.


During the late Jurassic period, the Allosaurus was at the top of the food chain. The two-ton dinosaur, which had a length of about 32 feet, was one of the largest dinosaurs in the Jurassic era. With a mouth full of serrated teeth, the Allosaurus most likely fed on large herbivores. Injuries and broken bones found in excavations indicate the Allosaurus didn't just pick on helpless prey; it's quite possible that the Allosaurus frequently picked fights with other large and dangerous dinosaurs, like the Stegosaurus.

Though the Allosaurus is a famous species of dinosaur, this will be the first time an adult Allosaurus has been featured in the franchise, however, cloned versions of the dinosaur did appear in Fallen Kingdom. According to Trevorrow, the juvenile Allosaurus in Fallen Kingdom will return in Battle of Big Rock as a fully-grown predator. The Allosaurus may set its sights on the human characters when they enter the park, which may be its new domain.
