What Is the Jaw Fossil?
The Jaw Fossil is a Pokémon fossil item. It represents the jaw of an ancient Pokémon.

Tyrunt has Rock/Dragon typing. This combination gives it several useful offensive options.
Tyrunt later evolves into Tyrantrum. Tyrantrum has much higher power and a strong physical attack stat.
Players often choose the Jaw Fossil when they want an aggressive Pokémon. Its design also appeals to fans of dinosaur-like Pokémon.

What Is the Sail Fossil?
The Sail Fossil is another ancient Pokémon fossil. It represents the sail-like structure of an ancient creature.
The fossil revives into Amaura in games where it appears. Amaura has a gentle appearance and a dinosaur-inspired design.
Amaura has Rock/Ice typing. This combination gives it access to powerful Ice-type attacks.
Amaura evolves into Aurorus. Aurorus keeps the Rock/Ice typing and becomes much larger.
The Sail Fossil suits players who want Ice-type coverage. It can also help teams that lack strong special attackers.
Jaw Fossil vs Sail Fossil: Main Differences
The biggest difference comes from the Pokémon each fossil creates.
| Feature | Jaw Fossil | Sail Fossil |
|---|---|---|
| Revived Pokémon | Tyrunt | Amaura |
| Final evolution | Tyrantrum | Aurorus |
| Main types | Rock/Dragon | Rock/Ice |
| Fighting style | Mainly physical | Mainly special |
| Evolution level | Tyrunt evolves at level 39 during the day | Amaura evolves at level 39 at night |
| Main strength | Physical power | Special attacks |
| Key appeal | Dinosaur-like attacker | Ice-type coverage |
| Best for | Aggressive teams | Coverage-focused teams |
The fossil choice does not have one universal answer.
Instead, consider your current team. Look at your team’s weaknesses and missing attack types.
Tyrunt and Tyrantrum Explained
Tyrunt is the Pokémon linked to the Jaw Fossil.
It has a small body but a fierce personality. Its Rock/Dragon typing gives it useful offensive moves.
Tyrunt evolves into Tyrantrum at level 39 during the day in the games where this evolution applies.
Tyrantrum becomes a powerful physical attacker. Its high Attack stat makes moves such as Rock-type and Dragon-type attacks useful.
Its ability, Strong Jaw, also supports certain biting moves. This ability increases the power of moves that use biting.
Tyrantrum can therefore fit teams that need physical damage.
However, its typing creates several weaknesses. Players should avoid sending it into poor matchups.
Amaura and Aurorus Explained
Amaura comes from the Sail Fossil.
It has a calmer design than Tyrunt. Its Rock/Ice typing gives it a very different role.
Amaura evolves into Aurorus at level 39 at night in the games where this evolution applies.
Aurorus focuses more on special attacks. It can use Ice-type moves to hit several common Pokémon types effectively.
Aurorus also has a large amount of HP. This can help it survive some attacks.
However, Rock/Ice typing creates several important weaknesses. Players should understand these weaknesses before building around Aurorus.
Its Ice typing can also provide valuable coverage against Flying, Ground, Grass, and Dragon Pokémon.

Which Fossil Is Better?
There is no single winner between the Jaw Fossil and Sail Fossil.
The Jaw Fossil usually suits players who want stronger physical offense. Tyrantrum can deal heavy damage with physical attacks.
The Sail Fossil suits players who want Ice-type coverage. Aurorus offers a different attacking style and team role.
Your existing team should guide the decision.
For example, imagine your team already has several physical attackers. In that case, Amaura may add more variety.
Now imagine your team lacks a strong physical attacker. Tyrunt may fill that role better.
Therefore, team balance matters more than the fossil’s appearance.
Jaw Fossil or Sail Fossil for Story Mode?
For a normal Pokémon adventure, both choices can work.
Tyrunt offers strong physical damage after evolution. Its Dragon typing also gives it useful offensive options.
Amaura offers Ice-type attacks that can help against several important matchups.
Your choice should depend on the Pokémon you already use.
If your team needs physical power, consider the Jaw Fossil.
If your team needs Ice coverage, consider the Sail Fossil.
You should also consider which Pokémon you enjoy using. Pokémon games are more fun when your team matches your personal style.
Real-Life Team Examples
Example 1: Your Team Needs Physical Power
Suppose your team already has several special attackers.
You may want a strong physical Pokémon.
In this situation, the Jaw Fossil makes sense.
Tyrunt can provide physical damage early. Tyrantrum becomes much stronger after evolution.
Example 2: Your Team Needs Ice Coverage
Suppose your team lacks Ice-type attacks.
The Sail Fossil could help fill that gap.
Amaura can learn Ice-type moves. Aurorus continues this role after evolution.
This choice can improve your team’s attacking coverage.
Example 3: You Prefer Dinosaur Designs
Some players simply choose based on appearance.
If you like aggressive dinosaur designs, Tyrunt may be more appealing.
If you prefer a larger, elegant prehistoric design, Amaura may win.
There is nothing wrong with choosing based on style.
Your Pokémon team should also be enjoyable to use.
