- Game Update - 27 July 2026
Eating from plants can drop berries onto the ground. Eating from trees can drop pods onto the ground. Eating from dinosaurs can drop meat chunks on the ground. Eating from these treats gives a substantial amount of growth points. (50x the normal amount of growth given by the source)Argentinosaurus' swimming offset has been updated.All dinosaur land speeds have been adjusted based on real estimates.Yhangchaunosaurus, deinocheirus, brachiosaurus, padillasaurus, argentinosaurus speeds were quadrupled because they were too slow to be at all playable if they remained their real-life speeds. Sarcosuchus, deinosuchus, and dimetrodon speeds were doubled for the same reason. Spinosaurus speed has been increased 8x. Stegosaurus, ankylosaurus, and kentrosaurus speed was increased 2.5x. Aerial dinosaurs' land speed has been increased up to 8x higher than their land speed estimates.All aquatic dinos…

- Multiplayer Update - 5 July 2026
Multiplayer mode has been added to the game and a game server is available for players to join!Your dead dinosaurs can now be revived after a certain amount of time passes after their death. The amount of time is based off the dinosaur's size category, with larger dinosaurs requiring more time to pass. (The previous nest point cost to revive was removed from the game, nest points may be used for something different in the future)Swapped some of the ground textures, rocks, grass, plants, and trees with more detailed models and textures.Added enhanced "umbra" shadows. This feature can be toggled in the game settings menu.

- Update 2026.6.7.3.0 - 7 June 2026
Reduced a set of lag spikes that occurred with the player. Reduced the amount of system memory the game uses from around 19gb down to around 9gb. Weather sounds are once again controlled by the weather volume slider. Fixed some cases of dinosaurs blinking in and out of visibility when they were coming into view. The quetzalcoatlus' carcass is now 1/3rd of its current size. Carnivores can no longer remove toxicity by eating fresh meat. They must eat minerals and then drink water like the herbivores have to do to remove toxicity. Your dinosaur's minimum growth rate is now 100% as a hatchling, 50% as a juvenile, 25% as a sub adult, and 0% as an adult. Eating enough of your preferred foods can increase this rate.

- Growth Rate Update and More - 19 March 2026
Hey everyone! Here is a list of all of the updates that have been released since the last patch notes!Also of note your dinosaur's growth rate requirements have changed and in order to grow you'll need to meet certain dietary requirements. To gain any growth in the Hatchling stage you need to have all of your Diets equal to or greater than 30% each.

- Accumulated Updates - March 13 - 13 March 2026
Hey everyone! Here are the patch notes for all of the updates that have went live in small unannounced patches since the last posted update.Important:I realized that I made the wrong decision when I dampened the accumulated growth of your creatures after reaching the adult stage in a previous update. Part of the fun of the game was growing larger than life creatures after reaching adulthood and that change hindered that activity. Now your previously acquired sizes are restored and continuing to grow after reaching adult is much more achievable. The only downside now is that if you die you lose 5% of your after-adult accumulated growth!New:Hatchlings have new idle, friendly, and aggressive call sounds. These are also temporarily being used for their juvenile call sounds. The species were broken down into a handful of major categories that each have their own sounds.Sub adults have new id…

These are gained from eating your general dietary needs. Having more gastroliths in your digestive system increases the nutrients gained from eating. Basic nutrients are now required for your diet ranking to be at its best. Basic nutrients are a buffer between poor diet and needing to have preferred foods in your diet to get higher diet rankings for benefits such as enhanced growth rate and trait bonus enhancements.Fixed grabbed dinosaur's position not being in the mouth due to the A* pathfinding scripts being enabled while being carried after a previous update.Baryonyx can now play its eating animation while swimming.Fish are now disappearing when fully eaten.
