10 Largest Dinosaurs in the ‘Jurassic Park’ and ‘Jurassic World’ Movies, Measured in Feet

by

As a huge film fan, I remember being blown away by Jurassic Park when it first came out! Michael Crichton’s novel was fantastic, but Steven Spielberg really made it special on the big screen. Since then, the series has expanded with six more films – three continuing the original story and four new Jurassic World movies. It’s incredible to think the entire Jurassic franchise has earned over $6 billion worldwide – it’s easily one of the most successful movie series ever made!

While Jeff Goldblum is a fan favorite, the real stars of the Jurassic Park movies are the dinosaurs themselves. These incredible creatures have thrilled and frightened audiences for over seven films. It’s hard to truly imagine being in that world, but this list of the 10 largest dinosaurs from the franchise will give you a sense of what it would be like to walk among these giants.

To calculate this, numerous resources were used and then averaged to provide a general idea.

Triceratops

9 Feet

The first Jurassic Park movie features a memorable scene where Sam Neill, Laura Dern, and Jeff Goldblum encounter a Triceratops during their tour of the island. Dr. Alan Grant, played by Neill, even touches the dinosaur affectionately. The Triceratops has become a signature dinosaur for the series, appearing in all of the films – even as an embryo in Jurassic World Rebirth.

Triceratops were large dinosaurs, reaching heights of 9 to 15 feet. They’re easily recognized by their horns and distinctive neck frill. Seeing one is breathtaking – both for characters like Dr. Grant in the movies and for viewers watching at home. It’s a consistently awe-inspiring sight throughout the film series.

9
Parasaurolophus

13 Feet

The Parasaurolophus is one of the dinosaurs that has been featured in all of the Jurassic Park/World movies. This plant-eating dinosaur is easily recognized by the large crest on its head. As seen in Jurassic World Dominion, Parasaurolophus travel in herds, like when Owen Grady (Chris Pratt) encounters a group of them in a snowy landscape.

These dinosaurs are quite large, typically standing 13 to 15 feet tall and reaching lengths of 30 to 33 feet. They’re generally peaceful animals and are often seen in groups. They mainly eat plants and don’t have many predators, likely because their size and appearance make them seem intimidating.

8
Tyrannosaurus Rex

At Least 13 Feet

As a huge movie fan, especially of this franchise, it’s always been tricky figuring out just how big the T-Rex really is. Some people say around 12 to 15 feet tall at the hips, which seems right. But others measure to the top of its head, even though it’s usually bent over, claiming it’s closer to 20 feet! Whatever the exact size, I’ll never forget the first time it burst onto the screen in the rain – genuinely terrifying! And it’s been fascinating to see it play both the monster and the unlikely hero throughout the films.

The Tyrannosaurus Rex has become a recurring hero in the Jurassic World films, notably rescuing Claire Dearing (Bryce Dallas Howard) and Grady. The first Jurassic World movie famously concludes with a battle featuring this dinosaur. It remains incredibly popular with fans and was instrumental in making the franchise a massive success.

7
Spinosaurus

16 Feet

Spinosaurus is a distinctive dinosaur known for its large, curved spine, which looks almost like a fin. It appears in the films Jurassic Park III and Jurassic World: Fallen Kingdom, where it’s shown causing trouble and even fighting a T-Rex by itself. Like the T-Rex, it’s a meat-eater, preying on any animal it encounters.

The Spinosaurus has made several appearances in the movie series, sometimes even as a skeletal display. This dinosaur is typically aggressive and stands about 16 feet tall.

6
Giganotosaurus

18 Feet

Once a dinosaur grows to over 18 feet tall, it becomes truly frightening. In Jurassic World Dominion, the Giganotosaurus is a powerful opponent for the T-Rex. The two dinosaurs have an epic battle while the team attempts to escape the island by helicopter. Ultimately, the T-Rex receives help from another dinosaur to defeat its rival.

This dinosaur is another meat-eater, and it only appears briefly before the final showdown. As its name suggests, it’s one of the largest predatory dinosaurs. Because of its size, scientists used its DNA to create the Indominus Rex, a powerful dinosaur featured in the Jurassic World movies.

5
Apatosaurus

20 Feet

The Apatosaurus was a truly massive plant-eater, growing as tall as 20 feet. These long-necked dinosaurs could reach lengths of up to 90 feet and are known for their gentle nature. They’re featured throughout the Jurassic World movies, peacefully wandering the landscapes of Isla Nublar.

The long-necked animals reach plants that other creatures can’t, making them well-suited to the island environment. Sadly, in Dominion, many are killed by the Indominus Rex simply for fun, as Grady observes. They deserve better than to be treated as scenery.

4
Therizinosaurus

20 Feet

The Therizinosaurus is a remarkably unusual dinosaur, reaching up to 40 feet in length and 20 feet in height. Despite being shown as blind in the movie Dominion, it relentlessly pursues and attempts to harm Claire, proving it’s a dangerous predator. It relies on its incredibly sharp senses to hunt and survive.

Despite first appearing as a threat, the dinosaur ultimately joins forces with T-Rex to defeat the Giganotosaurus in the film’s final battle. During this epic fight, the Therizinosaurus uses its keen senses to coordinate a powerful attack with T-Rex while the rest of the team escapes.

3
Indominus Rex

22 Feet

The Indominus Rex is a frightening, genetically engineered dinosaur featured in the Jurassic World movies. Created by Dr. Henry Wu (B.D. Wong) for the park in the first film, it quickly becomes a dangerous threat. After things go wrong at Jurassic World, the Indominus Rex causes chaos as the staff desperately try to escape.

The first movie ends with an unlikely alliance: the T-Rex and Owen Grady’s velociraptors working together to defeat the Indominus Rex. This massive creature stands 22 feet tall and is 19 feet long, and its powerful tail alone can cause significant destruction.

2
Mosasaurus

55 Feet Long

Let’s talk about the Mosasaurus, shall we? It’s not exactly a dinosaur you measure for height – being more like a giant, prehistoric fish. But 55 feet long? That’s massive! I first really noticed it in Jurassic World when things started going downhill fast. Remember poor Zara? That scene with the Pteranodons snatching her up while everyone else was scrambling to escape? Seriously shocking, and a real standout moment in the whole series.

Honestly, that scene where the Spinosaurus gets pulled under by the Mosasaurus is just unforgettable! It’s such a classic moment from the movie, and I think it really foreshadowed what would happen with the Indominus Rex. The T-Rex and raptors managed to push it back far enough that it ended up falling into the lagoon, and the Mosasaurus finished it off – it was a perfect full-circle moment!

1
Dreadnoughtus

30 Feet

The Dreadnoughtus is the largest dinosaur featured in the Jurassic films. Appearing in Dominion, the character Grant is amazed when he first sees one. This colossal dinosaur isn’t just the biggest; it’s also the heaviest, weighing over 130,000 pounds and reaching up to 85 feet long and 30 feet tall.

Its long neck is a key feature that identifies it as a titanosaur. The dinosaur shown in the movie was still growing, suggesting it could have become even bigger. The Dreadnoughtus perfectly represents everything that’s on the line in the Jurassic series.
