While some news aggregators were hastily reporting that the DLC was already available, the official release of Crocodilia Coast for Jurassic World Evolution 3 actually took place on August 11. And that isn’t the only thing hasty sources got wrong. Frontier Developments didn’t just add a set of new species to the game; they introduced an entire coastal ecosystem featuring the series’ first crocodilian, hundreds of decorations, and mechanics fans have been waiting for since launch. Let’s dive into the details—and find out which of the five new species are truly worth your money and which ones come for free.
Below is the full list of species, their unique abilities, exact pricing across all platforms, and a complete breakdown of the free Update 1.4. Spoiler: Elasmosaurus is making a comeback.

What Crocodilia Coast Adds—Five New Species with Unique Mechanics
Crocodilia Coast is a themed expansion focused on coastal fauna. Unlike standard DLCs, where new inhabitants are simply added to the roster, here each species has been given a lifelike quality—featuring full family groups with unique behaviors, intraspecies interactions, and even bioluminescent offspring. The developers at Frontier took a thorough approach: the expansion introduces not just skins, but entire ecosystem niches.
A total of five prehistoric species are being added to the game:
Deinosuchus—The Series’ First Crocodilian with the “Death Roll”
The giant Deinosuchus is the first crocodilian in the franchise’s history. This semi-aquatic predator boasts a bite force surpassing even that of the Tyrannosaurus: it lurks in the depths, waits for prey, and delivers a devastating strike using its signature “death roll.” With its long, broad snout, muscular tail, and quadrupedal gait, Deinosuchus is equally deadly on land and in the water. Its design clearly draws inspiration from real paleontology; this crocodylomorph lived during the Late Cretaceous period, approximately 82–73 million years ago.
Styxosaurus and Shonisaurus — Bioluminescent Marine Creatures
Named after the mythical River Styx, Styxosaurus is a long-necked plesiosaur and the first species in Jurassic World Evolution 3 to feature bioluminescent skin in its juveniles. The visual effect is impressive: the young glow in the dark, while adult males display unique patterns and coloration.
Shonisaurus, a giant ichthyosaur from the Late Triassic, rounds out the aquatic collection. Both species are introduced as complete family groups, featuring both juveniles and adults.
Postosuchus and Desmatosuchus — a terrestrial predator and a herbivore
Postosuchus is a bipedal predator—a distant relative of modern crocodiles—featuring armored skin and dagger-like teeth. In a recent gameplay trailer, the developers showcased the unique behavior of the entire family group within their enclosure for the first time: Postosuchus individuals stalk visitors and grab them with their forelimbs.
Desmatosuchus is the exact opposite: a herbivorous relative of crocodiles featuring powerful shoulder spikes and bony plates along its back that deter predators. Its calm temperament makes it an ideal candidate for spacious, open-air enclosures.
Where to buy Crocodilia Coast and how much it costs
Crocodilia Coast is available on PC (Steam and Epic Games Store), PlayStation 5, and Xbox Series X|S. The recommended retail price is $14.99/£11.99/€14.99. On Steam, the DLC costs HK$102.
The base game, Jurassic World Evolution 3, is required to play. Please note: if you are using the Windows version, a Steam account is required.
Free Update 1.4 — what all players get
As a tribute to the series’ fans, all owners of the base game will receive the free content update 1.4.0 alongside the paid DLC.
The Return of the Elasmosaurus
The centerpiece of the update is the return of the Elasmosaurus from Jurassic World Evolution 2. In this third installment, the plesiosaur has been revamped: it is now available as a full family group—complete with juveniles—rather than as a solitary individual.
New Decorations and Sandbox Settings
The building editor has been expanded to include “Clear Glass” modular decorations, which can be used for enclosures, viewing platforms, and walkways. New settings have also been added to Sandbox mode, offering greater freedom when customizing parks.
Hawaii Map and Steam Workshop
Update 1.4 introduces a square Hawaii map for Sandbox mode, as well as support for the Steam Workshop (including Workshop Collections), allowing players to share their creations.
Is Crocodilia Coast Worth Buying? A Value Breakdown
For $15, you get five new species with unique behaviors not found in the base game, plus a set of 274 new items for building coastal areas: boardwalks, waterside huts, signage, decorations, interior furnishings, and 13 pre-made blueprints.
Importantly, the DLC contains exclusively Crocodilia Coast content—species and decorations. All gameplay mechanics (family groups, offspring, bioluminescence) are available in the base game for free. Meanwhile, the free 1.4 update adds the Elasmosaurus, glass decorations, and new sandbox settings; this is not a replacement for the DLC, but a supplement to it.
Verdict: If you actively build coastal parks and want a wider variety of aquatic and semi-aquatic creatures, the DLC is worth the price. If the Elasmosaurus from the free update is enough for you, you might want to wait.

Conclusion:
Crocodilia Coast is available now on PC, PS5, and Xbox Series X|S. Frontier Developments didn’t just roll out another species pack—they added the game’s first crocodilian family, bioluminescent juveniles, and hundreds of building elements. If you want to turn your parks into true coastal sanctuaries, now is the perfect time.
