How to Get Spinosaurus in My Dino Park
Spinosaurus is the best non-Legendary dinosaur in My Dino Park — it earns more per minute than every other Epic and Rare. But it only hatches from the $25,000 Epic Egg, which shares a 50/50 roll with Triceratops. Here is the real cost, the roll odds, and the honest verdict on whether it beats saving for a guaranteed T-Rex.
The Short Answer
Spinosaurus is an Epic dinosaur and the Epic Egg is its only source. There is no quest, no level gate and no direct purchase — you buy the egg, wait out the hatch and hope the roll lands on Spinosaurus. The numbers below use the egg price, not the dinosaur value, because the egg price is what actually leaves your balance.

⚠️ You cannot target it The Epic Egg lists Spinosaurus / Triceratops as its possible outcomes, so every $25,000 spend is roughly a 50% shot at Spinosaurus. Never spend your last Cash on one roll — budget for at least two.
There Is No "Buy Spinosaurus" Button
Spinosaurus is listed at $25,000, and because that happens to equal the $25,000 Epic Egg price, the number looks honest. The catch is that you still cannot buy the dinosaur directly — the egg is the only path, and the roll can miss, so the amount you should plan for is higher again.

📉 The uncomfortable coincidence The expected cost of targeting one Spinosaurus is $50,000 — exactly the price of the Legendary Egg, which hatches a guaranteed T-Rex earning $2,500 per minute instead of $1,400. If Spinosaurus is a goal rather than a happy accident, the same Cash buys nearly twice the income with none of the RNG. Compare with T-Rex →
Epic Egg Roll Odds
The game does not publish drop rates, so this table assumes an even split across the 2 outcomes the Epic Egg lists. Treat it as a planning floor, not a guarantee — real rates could be weighted either way.
| Eggs bought | Cash spent | Chance of a Spinosaurus | What it means |
|---|---|---|---|
| 1 | $25,000 | 50.0% | A coin flip. Fine if you would be happy with either dinosaur. |
| 2 | $50,000 | 75.0% | The break-even point most players plan around. |
| 3 | $75,000 | 87.5% | Still a one-in-eight chance of walking away without one. |
| 4 | $100,000 | 93.8% | Diminishing returns — you have now spent two Legendary Eggs. |
| 5 | $125,000 | 96.9% | Chasing at this point costs more than the entire rest of your roster. |
Cumulative probability of at least one Spinosaurus across repeated rolls, assuming independent draws and an even split across the 2 listed outcomes.
Spinosaurus or Triceratops: Which Roll Is Better
Both dinosaurs come out of the same $25,000 egg, so the fair comparison is what each one returns on that identical spend. Payback here is measured against the egg price, which is why both numbers are worse than the values you see on tier lists.
| Roll outcome | Listed value | Income | Payback vs egg | Fully upgraded |
|---|---|---|---|---|
| 🐊 SpinosaurusEpic | $25,000 | $1,400/min | 17.9 min | $15,120/min |
| 🦕 TriceratopsEpic | $20,000 | $1,200/min | 20.8 min | $12,960/min |
🎲 Spinosaurus is the better half of the egg Spinosaurus earns 16.7% more per minute than Triceratops for the identical egg price, which makes it the better outcome on every measure. Averaged across both possibilities the Epic Egg pays itself back in 19.2 minutes — a solid buy overall, and the stronger of the two rolls when it lands.
How Long $25,000 Actually Takes
Time to bank the Epic Egg price at five real park stages, using this site dinosaur and upgrade data. Notice how the upgrade multiplier compresses the wait far more than adding dinosaurs does.
| Park stage | Dinos | Multiplier | Income | Time to afford |
|---|---|---|---|---|
| Fresh start | 1 | ×1 | $50/min | 8h 20m |
| Starter park | 4 | ×1 | $475/min | 53m |
| Starter + 2 upgrades | 4 | ×1.8 | $855/min | 29m |
| Mid park | 9 | ×1 | $2,925/min | 9m |
| Mid park, fully upgraded | 9 | ×10.8 | $31,590/min | 1m |

Four Mistakes People Make Chasing Spinosaurus
✕ Expecting a direct purchase
Spinosaurus is listed at $25,000, which equals the Epic Egg price, but the shop has no direct option. The only way in is the egg, and the roll can hand you a Triceratops instead.
✕ Rerolling until it appears
Each egg is an independent draw, so a miss does not improve your next odds. Every extra roll is another $25,000 with the same coin flip attached.
✕ Selling a Triceratops to reroll
Triceratops earns less per minute than Spinosaurus, but it is still a solid Epic. Trading a guaranteed earner away to gamble for a slightly better one costs income twice over.
✕ Buying Epic Eggs before the cheap upgrades
Visitor Booth and Food Court cost $10,000 combined and multiply your entire roster by 1.8. Buying them first makes every later egg easier to afford.

How do you get Spinosaurus in My Dino Park?
Buy the Epic Egg for $25,000 Cash in the in-game shop, wait out the 1-minute hatch, then place the dinosaur in a free pen. The Epic Egg is the only source, and it can also hatch a Triceratops instead.
How much does Spinosaurus cost?
The dinosaur is listed at $25,000, and that happens to be the exact Epic Egg price. You cannot buy it directly — you pay $25,000 for the egg and take the 50/50 roll.
Is the Epic Egg guaranteed to hatch a Spinosaurus?
No. The Epic Egg lists Spinosaurus and Triceratops as its possible outcomes, so a single egg is roughly a coin flip. Two eggs put you at about 75% and three at about 87.5%.
How much does Spinosaurus earn per minute?
$1,400 per minute at base rate. With all four park upgrades active the multiplier is 10.8, which lifts a single Spinosaurus to about $15,120 per minute, or $907,200 per hour.

Is Spinosaurus the best dinosaur that is not T-Rex?
Yes. At $1,400 per minute it out-earns every other Epic and Rare dinosaur in the game, which makes it the strongest non-Legendary you can field.
Should I chase Spinosaurus or save for T-Rex?
Save for T-Rex if you are choosing deliberately. Targeting a Spinosaurus costs $50,000 on average, which is exactly the guaranteed Legendary Egg price, and T-Rex earns $2,500 per minute versus $1,400 with no RNG involved.
Can I get Spinosaurus for free with codes?
Indirectly. The 11 active codes are worth $171,650 in Cash, which funds 6 Epic Eggs with $21,650 left over — about 3 expected Spinosaurus at even odds, before your park earns anything.
