Mesozoico Guide: How to get started
About
OverviewMesozoico is a Roblox survival game where you play as a mesozoic animal, eat, grow, and fight to stay alive. The game is in alpha, so bugs can happen, and the developers have designed it so that unfair deaths are part of the experience. This guide covers how to start, how to grow faster, how to manage your stats, and how the main playable animals fight.

How to get started
Step
The game's three opening badges tell you exactly what to aim for early on: play as a mesozoic animal, grow one to 100%, and land your first attack on another player. Jumping straight into a large carnivore makes all three harder than they need to be.
- Pick a starter begin as Microraptor or a herbivore so you can learn where food spawns without fighting anything dangerous.
- Find food quickly eat whatever your animal prefers until your nutrition climbs above 70%, which triggers a 20% growth speed bonus called Nourished.
- Avoid sprinting everywhere running constantly builds fatigue, which lowers your maximum stamina; walk between locations and only sprint when ambushing or fleeing.

Nutrition and the Nourished bonus
Tips
Every animal has a preferred diet, and eating those foods raises nutrition more efficiently than neutral ones. Keeping nutrition above 70% keeps the Nourished buff active, which stacks with normal growth and also speeds up the Elder phase later.
- Maiasaura, Achelousaurus, Papiasaurus, and Fabrosaurus all get good nutrition from Fruit, which is an uncommon bush that spawns on the ground but not on rocks.
- Gallimimus, Pachycephalosaurus, and Beishanlong can eat Fruit but gain very little nutrition from it.
- Miragaia prefers Fern over anything else, while Achelousaurus prefers Fruit and dislikes Fern.
- Carnivores get nutrition from specific prey animals listed in their diet; after a kill, sit on the body and eat until it disappears so nothing is wasted.
- When Fruit spawns it produces a blue plume when sniffed, making it easier to spot.
Cleanliness — the stat players forget
WarnCleanliness does not affect your combat stats directly, but it drags down your ability to recover from bleed and other injuries. The debuff scales gradually from the 60% mark down to 0%, where every form of healing is reduced by 30%. Entering any large body of water — a lake or a river — restores cleanliness from zero to full in around ten seconds.
The Elder system
Check
Once you hit 100% growth, an Elder button appears in the info menu just above your growth meter. Pressing it twice starts the process after a warning screen. You cannot undo it, and the total time required is three times your normal growth duration.
- The Elder button only appears at 100% growth.
- The boost is roughly 20% to size and stats, but stamina drain and food requirements also rise by 20%.
- Maiasaura, Ceratosaurus, Siamotyrannus, Achelousaurus, and Miragaia gain the most from Eldering.
- The first 10% of Elder growth takes your normal growth time, and the last 10% takes twice that.
- Keep nutrition above 70% during Eldering the Nourished bonus applies and shortens the process.
- Eldering cannot be reversed.
Combat basics for each animal
TableThe animals below each have one ability that defines their combat style and one threat that counters them hardest. Learn both before picking a fight.
| Ceratosaurus | key move is Force Sit, which stops the target from fighting back; chain it so packmates get free bites, and use Fracture on large legs for around 315N of damage. |
| Achillobator | key move is Latch, available above 40% growth; bite while latched and get off when stamina is low, then rest on a rock while packmates keep the target busy. |
| Miragaia | key move is Thagomizer, an omnidirectional tail whip dealing 275N fully grown; always keep your tail facing attackers and never let anyone reach your neck. |
| Concavenator | key move is Tail Whip, which applies 7% stress per hit and can blind targets; use water to ambush and regenerate stamina, and avoid prolonged fights on land. |
| Achelousaurus | key move is Counter, which reflects 75% of incoming damage and deals 135N back to the attacker; time it against Siamotyrannus bites or Ceratosaurus fractures. |
| Beishanlong | key move is Body Slam, which builds momentum for up to 180N on the first hit; manage distance carefully because stamina runs out fast if charges miss. |
Stamina management in a fight
Tips
Every ability in the game costs stamina, and most animals become nearly helpless when it is gone. The following habits apply across all animals.
- Walk between locations and only run when ambushing or escaping — sprinting everywhere is the fastest way to reach fatigue.
- Fatigue builds from long runs and reduces your maximum stamina until you rest.
- For Ceratosaurus, each Force Sit and Fracture use a large chunk of stamina, so walk into fights with a full bar.
- Achillobator consumes less stamina when latched onto a swimming target.
- Concavenator's Tail Whip costs significant stamina and slightly slows movement.
- Miragaia's Thagomizer has a noticeable cooldown that skilled attackers will bait — wait for a real opening rather than swinging freely.

Common questions
FAQCan I play on a console?
You can open the game on a console, but console controls have not been added. You need to connect a keyboard and mouse to your console to play properly.
How do I grow faster?
Keep your nutrition above 70% to stay in the Nourished state, which adds 20% to your growth speed. Eat your animal's preferred foods to raise nutrition efficiently, and the same bonus applies while you are Eldering.
Is Eldering worth it for every animal?
Eldering raises stats by roughly 20% but also raises stamina drain and food needs by 20%, and it cannot be undone. Large animals like Maiasaura, Ceratosaurus, Siamotyrannus, Achelousaurus, and Miragaia benefit most.
How many animals can be in one pack?
Pack sizes vary by species: Achillobator allows up to 6, Achelousaurus up to 5, Ceratosaurus up to 3, and Concavenator up to 2.
