Update 9 (EA 1.6.4) was the ninth content, and second major update to Prehistoric Kingdom.
This patch introduces 4 new animals, swimming, a new map, biome, as well as a new selection of font styles.
This release also adjusts our version numbers to better reflect our original versioning scheme, which we were too silly to follow through on. Oopsies!
Your patience this year has been greatly appreciated, and we look forward to sharing our plans for Prehistoric Kingdom with you in January’s Dev Diary in 2024. For all the details on what's changed in Update 9, please be sure to read the full patch notes at the bottom of this post!

Update 9 Features[]
Animals[]
Expand your kingdom's collection with 4 brand new species: Ouranosaurus, Muttaburrasaurus, Carcharodontosaurus and Spinosaurus!
| Animal | Period | Description |
|---|---|---|
 |
Cretaceous | Carcharodontosaurus's name is not only a mouthful, but was actually inspired by the Great White Shark’s scientific name: Carcharodon! We reckon your guests will be screaming to see this dinosaur in action. |
 |
Cretaceous | With a distinct nose and snuffly vocalizations, Muttaburrasaurus will bring some Australian representation to your park. |
 |
Cretaceous | Having once roamed the prehistoric floodplains of West Africa, Ouranosaurus is best known for its stunning sail made up of tall vertebrae. |
 |
Cretaceous | Hailing from Cretaceous North Africa, Spinosaurus gets its name from the tall spines that make up the iconic sail it is known for. |
Swimming[]
Take the plunge with swimming! This new behaviour allows animals to cross rivers and explore deep water bodies by swimming across the surface.
Every species has varying degrees of water affinity, meaning that some animals like Spinosaurus frequently try to seek out water, while other species will try to avoid it all costs.
New Map: Tanzania[]
Build in the heart of the savanna with our new map set in the grassland biome. With sparse vegetation and flat terrain, this location is perfect for builders!
New Biome: Grassland[]
Adding 9 new types of plants, the grassland biome is one of our most versatile climates yet. Alongside classic trees like the Acacia, the grassland biome also comes with, well... grasses!
New Fonts[]
A collection of new styles are now available for the modular letter pieces. Coming in a range of different themes, these fonts are the perfect way to change up your park's signage.
[]
Due to the introduction of water-based locomotion, all navmeshes will have to be regenerated! This means that upon initial load, your saved games may take longer to enter. Please resave your games once loaded in.
We have also made slope limit changes to the navmesh, so if you had animals that we were previously stuck in surprising places (e.g. rocks, roofs) you'll have to move them back down to an appropriate area.
Known Issues & Additional Notes[]
- We will be fixing as many crashes as possible as they're reported. Please send feedback and bug reports to our Discord server's appropriate channel.
- Muttaburrasaurus is missing Nigel voicelines! We will be adding them next year when we do our next recording session with Nigel
- We’re still tuning the render distance for small objects, so some items may disappear sooner than expected
- Animals do not animate while in the Nursery due to the new locomotion system. They will animate again in the future
- Animal IKs are a work in progress and will be improved in future updates
- Animals may jitter when resting or sleeping in shallow water
- Guests can pick some pretty funky paths! We're in the middle of reworking our technical backend for path choices, so this will be fixed in a following update

- Foliage
- Added Acacia 1, 2, 3
- Added American Tarwort 1, 2
- Added Digitaria Dry Grass 1, 2
- Added Digitaria Grass 1, 2
