How to Get Compsognathus in My Dino Park
Compsognathus is listed at $500 — and the Common Egg that hatches it costs exactly $500. It has the fastest payback of any dinosaur in the game at 10 minutes, but the lowest income at $50 per minute. Here is the real math, the roll odds, and why it is your launch pad rather than your end goal.
The Short Answer
Compsognathus is a Common dinosaur and the Common Egg is its only source. It is the first dinosaur most players ever hatch. The egg costs the same as the dino is worth, so there is no markup to warn about — but also no hidden discount. Buy it to start the income loop, then reinvest the $50 per minute into better eggs.

✅ The price tag is exactly the egg Every other acquisition guide on this site has to warn you that the egg costs more than the sticker. Not here. Compsognathus is valued at $500, and the Common Egg that produces it is $500 — you pay $0 less than the number on the card, because the two numbers are the same. Payback is 10.0 minutes on paper and 10.0 minutes in practice, since there is no premium to strip out.
The $500 Price Tag Is Exactly What You Pay
Tier lists quote the $500 dinosaur value. That is an in-game valuation used for comparison, not a purchase price. The only route to a Compsognathus is the $500 Common Egg, which costs exactly the same — no markup, no discount. The number on the card is honest here.

📈 It leads the speed chart Rank the whole roster by sticker payback and Compsognathus sits 1 of 12 at 10.0 minutes — the fastest in the game. Re-price every dinosaur at the egg you actually have to buy and it slips to 3 of 12 at 10.0 minutes, because Dilophosaurus and Gallimimus earn more from the same $500 egg. Still a top-three payback either way.
All 3 Common Egg Outcomes, Ranked
The $500 Common Egg lists 3 possible dinosaurs, so each roll is roughly a 33% shot at any one of them. Here is what each result is actually worth at the same egg price — because you paid the same amount no matter which one appears.
| Result | Listed value | Income | Payback at egg price | vs Compsognathus | Maxed income |
|---|---|---|---|---|---|
| 🦎 DilophosaurusCommon | $1,500 | $100/min | 5.0 min | +100% | $1,080/min |
| 🏃 GallimimusCommon | $1,000 | $75/min | 6.7 min | +50% | $810/min |
| 🐣 CompsognathusCommon | $500 | $50/min | 10.0 min | — | $540/min |
🎲 Third of three — and that is fine Compsognathus lands 3 of 3. Only Dilophosaurus beats it, by 100%, and 0 of the 3 results are worse — it is the floor of the pool. But the floor of the Common Egg is still a working dinosaur that fills a slot and earns. You are not gambling on a jackpot here; you are buying the cheapest possible start.
How Many Eggs Until a Compsognathus?
Each roll is independent, so a miss never improves the next attempt. With 3 outcomes the per-egg chance is about 33%. The last two columns are the ones that matter — they show what you own regardless of whether the roll cooperates.
| Eggs | Total spend | Chance of ≥1 | Slots filled | Income either way |
|---|---|---|---|---|
| 1 | $500 | 33.3% | 1 | $75/min |
| 2 | $1,000 | 55.6% | 2 | $150/min |
| 3 | $1,500 | 70.4% | 3 | $225/min |
| 4 | $2,000 | 80.2% | 4 | $300/min |
| 6 | $3,000 | 91.2% | 6 | $450/min |
| 8 | $4,000 | 96.1% | 8 | $600/min |
| 10 | $5,000 | 98.3% | 10 | $750/min |
🧠 Do not target it — just buy eggs Targeting one specific Compsognathus takes 3 eggs on average, or $1,500, which works out to a 30.0 minute payback against the 10.0 minutes you get from a single egg. But those 3 eggs are not wasted — they fill 3 enclosures and earn roughly $225 per minute combined whatever hatches. Buy the egg for the tier, not for the dinosaur.
The $500 Decision: Egg or Save?
Across this site the answer is usually "buy the upgrade first". Compsognathus is the opposite end of the scale: at $500 the Common Egg is the only thing you can afford, and a Visitor Booth costs $2,000. In a brand-new park earning nothing yet, there is no contest — the egg is the only move that starts the loop.
$500 Common Egg
Adds one new dinosaur to an empty enclosure. Expected income across all three possible results is $75 per minute.
+$75/min
Roughly 33% of a starter park, from a single purchase
$2,000 Visitor Booth
Multiplies everything you already own by a flat 20%. Powerful later, but it can only scale what is already there — and you own nothing yet.
+$45/min
A 20% lift on a park that is barely earning yet
🧮 The exact break-even The Common Egg costs $7 for every $1 per minute it adds. A Visitor Booth only beats that rate once your park already earns $1,500 per minute. A full Common starter park makes $225 per minute — well under the line — so the egg wins by 1.7×. Cross $1,500 per minute and the answer flips permanently to upgrades. See the full upgrade order →
Where a Cheap Dinosaur Stops Being the Right Answer
Compsognathus is efficient per dollar but tiny per enclosure, so the correct answer depends entirely on which resource is scarce. Take $50,000: it buys exactly one T-Rex at $2,500 per minute in a single slot, or 100 Common Eggs at roughly $7,500 per minute across 100 slots — 200% more income, if and only if you have the space.

One Legendary out-earns one Compsognathus by this much in the same space. Once enclosures run out, only this ratio matters.
⚖️ The rule Compsognathus is the right buy while Cash is your bottleneck, and the wrong buy the moment enclosures become the bottleneck. It takes 33 average Common rolls to match one T-Rex, and a T-Rex out-earns a Compsognathus 50.0 in the same slot. So fill every empty space cheaply first, then start replacing the weakest residents from the top down. Plan your enclosures →
How Long to Save $500
Income figures below are computed live from the dinosaur table, so they match what your park actually produces at each stage. The Common Egg is the first purchase every player makes, and these are the realistic waits to afford one.
| Park stage | Dinos | Multiplier | Income | Time to afford |
|---|---|---|---|---|
| 1 Compsognathus | 1 | ×1 | $50/min | 10m |
| Full Common starter | 3 | ×1 | $225/min | 2m |
| Starter + Visitor Booth | 3 | ×1.2 | $270/min | 2m |
| Starter + Booth + Food Court | 3 | ×1.8 | $405/min | 1m |
🎁 The free-code shortcut The 11 active codes are worth $171,650 in Cash, which buys 343 Common Eggs with $150 left over — around 114.3 expected Compsognathus and roughly $25,725 per minute across 343 filled slots. The same Cash spent on Legendary Eggs buys 3 T-Rex for $7,500 per minute, so the Common route is 3.43× the income if you have the space for it. Grab every active code →
Every Dinosaur, Priced at the Egg You Actually Buy
Standard tier lists divide the listed value by income, which flatters expensive dinosaurs and punishes cheap ones. This table uses the egg price you genuinely pay. Compsognathus moves from 1 of 12 to 3 of 12, and the whole game's cheap end looks even stronger than advertised.
| # | Dinosaur | Source egg | Real cost | Income | Payback at egg price |
|---|---|---|---|---|---|
| 1 | DilophosaurusCommon | Common Egg | $500 | $100/min | 5.0 min |
| 2 | GallimimusCommon | Common Egg | $500 | $75/min | 6.7 min |

| 12 | TriceratopsEpic | Epic Egg | $25,000 | $1,200/min | 20.8 min |
Compsognathus ranks 3 of 12 on real cost — the third-fastest payback in the game, behind only Dilophosaurus and Gallimimus. But it caps at $50 per minute, so it stops mattering once you can afford a Rare or Epic egg.
A Maxed-Out Compsognathus
Stacking all four park upgrades multiplies every dinosaur by ×10.8 for a total of $80,000. Compsognathus contributes 0.6% of a full 12-dinosaur park income for 0.3% of its cost — one of only a handful that pull more weight than they cost.

The multiplier applies to every dinosaur equally, so it never changes which one is the better buy — it only shortens every payback in the park at the same rate.
Four Mistakes to Avoid
✕ Saving to the $500 listed price
You never need that much. The Common Egg is $500, and there is no direct purchase option in the shop. Saving a single cent more than $500 is a waste — the egg and the sticker are the same number.
✕ Rerolling away a Dilophosaurus
Dilophosaurus earns 100% more per minute than Compsognathus from the identical $500 egg. It is the best result in the pool. Keeping the worst roll instead of the best is a straight income loss.
✕ Buying upgrades before filling your slots
A Visitor Booth multiplies what you own. In a $0 per minute brand-new park that is $0 per minute, against $50 from one egg. Multipliers need something to multiply — buy the egg first, then scale it.
✕ Still buying Common Eggs after $1,500 per minute
Past that income the Visitor Booth returns more per dollar than another Common roll, and by the time enclosures are full the Rare and Epic tiers earn far more per slot. Cheap and efficient stops being the same thing.

How do you get Compsognathus in My Dino Park?
Buy a $500 Common Egg from the in-game shop, wait the instant hatch and place the dinosaur in an empty enclosure. The Common Egg is the only source, and it can also hatch Gallimimus or Dilophosaurus instead.
How much does Compsognathus cost?
The dinosaur is listed at $500, and that is also the price. You cannot buy it directly — you pay $500 for the Common Egg, which is the same figure. Unlike most dinosaurs, there is no markup between the sticker and the egg.
Is the Common Egg guaranteed to give Compsognathus?
No. The Common Egg lists three possible outcomes, so a single egg is about a 33% shot at Compsognathus specifically. Two eggs reach roughly 55.6%, three reach 70.4% and ten reach 94.4%. Every miss still hatches a working dinosaur, so no roll is wasted.
How much money does Compsognathus make per minute?
$50 per minute at base rate, paying back the $500 egg in 10.0 minutes. With all four park upgrades active the ×10.8 multiplier lifts a single Compsognathus to $540 per minute, or $32,400 per hour, and payback drops to about 0.9 minutes.
Is Compsognathus the best Common dinosaur?
No, Dilophosaurus is. It earns $100 per minute against Compsognathus at $50 from the same $500 egg, which is 100% more. Compsognathus is third of the three possible results, behind Dilophosaurus at $100 and Gallimimus at $75.
Is Compsognathus worth buying?
Yes, as your first dinosaur. Priced at the egg you actually buy, it pays back in 10.0 minutes and ranks 3rd of 12 — behind only Dilophosaurus and Gallimimus, and ahead of every Rare, Epic and Legendary dinosaur in the game.
Should I buy a Common Egg or a Visitor Booth first?
The egg, until your park earns $1,500 per minute. Below that line the egg adds more income per dollar; above it the Visitor Booth multiplier pulls ahead. A full Common starter park makes $225 per minute, so the egg wins by about 1.7× at that stage.
Can I get Compsognathus for free with codes?
Indirectly, yes. The 11 working codes are worth $171,650 in Cash, which buys 343 Common Eggs with $150 to spare — roughly 114.3 expected Compsognathus at even odds, and about $25,725 per minute of new income across 343 filled slots.
