What is Skeletal Dunkleosteus in Steal An Egg?
Skeletal Dunkleosteus is the bone-white version of Dunkleosteus, one of the six prehistoric animals in the Extinction Egg. It swaps the normal fish-armored look for a skeletal one and pays out more cash per second.
You do not pick this version on purpose. Every Extinction Egg hatch has a small separate chance to reroll whatever base animal you got into its Skeletal form, and Dunkleosteus is one of the six it can happen to.
Because the reroll is rare on top of an already random base pull, Skeletal Dunkleosteus is one of the harder catches from this egg.

How to get Skeletal Dunkleosteus
Is Skeletal Dunkleosteus good?
Strengths 4
- Pays more per second than the normal Dunkleosteus.
- A Skeletal pet is an instant show-off since the reroll is rare.
- Extinction Egg also drops other strong prehistoric pets while you farm for it.
- Fits the growing Skeletal set alongside
Skeletal Sabertooth and 
Skeletal Gigantus.
Weaknesses 4
- You cannot target it directly: it needs the base Dunkleosteus pull plus the separate Skeletal reroll.
- The base Extinction Egg pool has several other animals competing for the same hatch.
- No confirmed way to boost the Skeletal reroll odds.
- The base, non-Skeletal Dunkleosteus is not shown as its own tracked pet yet, so its plain income is not published.
How to use Skeletal Dunkleosteus well
- 01
Farm Extinction Eggs in bulk rather than one at a time, since both the base pull and the reroll are random.
Grinding - 02
Keep any Skeletal pet you roll, even a low one, since the reroll itself is the rare part.
- 03
Track which base animals you still need from the Extinction Egg pool so you are not only farming for Dunkleosteus.
Did you know?
Dunkleosteus was a real armored prehistoric fish, which explains the bony plated look on both versions.
The Skeletal line runs across several Extinction Egg animals, not just this one.
