Hope you are fresh and fine my brother/sister…
Ever heard of a dinosaur that looks like a giant chicken? Sounds like something straight out of a weird dream, right? But guess what? It’s real. And it has a name that sounds even crazier — Anzu Wyliei, also known as the “chicken from hell.”
This dinosaur is one of the most exciting finds in recent science history. It’s not just because it looks like a bird, but because it brings us one step closer to understanding how chickens and dinosaurs are closely related.
If you skip this article, you’ll miss out on some wild facts, jaw-dropping discoveries, and some good ol’ fossil science that ties chickens to ancient creatures that roamed the Earth millions of years ago. So stay with me — it’ll be worth your while.
What is the Dinosaur That Looks Like a Chicken?

Let’s not keep you waiting. The dinosaur you’re thinking of is called Anzu Wyliei. Scientists often refer to it by its nickname — “chicken from hell.”
Why such a name?
- “Anzu” comes from a demon bird in Mesopotamian mythology.
- “Hell” comes from the Hell Creek Formation, where it was discovered.
- And “chicken” — well, just look at it!
Anzu had feathers, a beaked mouth, long legs, and a slender body. It’s like a chicken that got too big for the coop — human-sized, actually!

The Dinosaur in Question: Meet Anzu Wyliei

Anzu Wyliei is not a new myth. It’s a real species that lived around 66 million years ago, during the late Cretaceous period. It belonged to a group of dinosaurs called Oviraptorosaurs — creatures known for their bird-like features.
🦴 Key Facts:
- Size: About 10 feet long and 5 feet tall.
- Weight: Roughly 500 pounds.
- Found in: Hell Creek Formation (North and South Dakota, USA).
- Discovered by: A team of scientists in 2014.
- Skeleton evidence: Three main fossils helped confirm this species.
Why It Looks Like a Chicken

So, what gives Anzu its “chicken vibe”?
- Feathers – Fossils show it had long feathers, just like birds.
- Beak – No teeth, just a beak like a modern bird.
- Long legs – Great for running and moving fast, like an animal on the move.
- Crested head – A tall crest like a rooster’s crown.
These features make it a perfect blend between a bird and a dinosaur.
🧠 In a study, scientists said Anzu was one of the most bird-like dinosaurs discovered in North America. And yes, chickens are distant relatives!
Behavior and Diet
Was Anzu a meat-eater? A plant-eater? Or something else?
Turns out, it was probably omnivorous — eating both plants and small animals.
🔍 Based on fossils and jaw bones, here’s what it likely ate:
- Small reptiles or mammals 🐭
- Seeds 🌱
- Insects 🐜
- Possibly eggs 🥚
Its beak wasn’t built for tearing meat like a T. rex, but more for picking, cracking, or pecking — kind of like a modern chicken.
Importance in Evolution
You may ask — why should we care?
Well, Anzu helps fill a huge gap in our understanding of how birds evolved from dinosaurs. It gives strong evidence that birds didn’t just come after dinosaurs — they are dinosaurs!
Here’s what Anzu teaches us:
- Birds and dinosaurs share a common ancestor
- Chickens have ancient dinosaur DNA
- The line between birds and reptiles isn’t so clear after all
Yes, the chicken you eat today may have come from a dinosaur. Mind-blowing, right?
Where to See Anzu Today
If you’re eager to see this chicken dinosaur up close, head to:
🏛️ Carnegie Museum of Natural History – Pittsburgh, USA
This is where you’ll find a full model and some original bones of Anzu. It’s part of their fossil exhibit and a big draw for dinosaur fans.
Fun Facts About the “Chicken Dinosaur”
- Nickname: “Chicken from Hell” (scary and silly at the same time).
- Anzu means: A demon bird from ancient myth.
- Fossils found in: Hell Creek Formation, a hotspot for dinosaur remains.
- Cretaceous period: Same time as T. rex.
- It ran fast: Thanks to long legs and light bones.
- Not a bird: But had feathers and beak like one.
- New species: Only officially discovered in 2014.
Are Chickens Dinosaurs? Yes or No?
✅ Yes. Scientists agree that birds, including chickens, are direct descendants of dinosaurs.
In fact, studies show that chickens are more closely related to T. rex than any lizard or crocodile. The genetic evidence is clear.
What About Chickenosaurus?
Some scientists, like Jack Horner, believe we could one day reverse-engineer a chicken to look like a dinosaur — a chickenosaurus.
Here’s how:
- Tweak chicken DNA
- Reactivate ancient dinosaur genes
- Bring back traits like tails, teeth, and claws
Is it science fiction or future fact? Only time will tell. But the news from labs shows we’re getting closer.
FAQs (Frequently Asked Questions)
What dinosaur is similar to the chicken?
Anzu Wyliei and other Oviraptorosaurs look a lot like chickens.
Is Anzu a demon?
Not really. The name comes from a mythological demon bird.
Did Anzu live with T. rex?
Yes! Both lived in the Hell Creek Formation during the Cretaceous period.
How big is Anzu?
Anzu was around 10 feet long and 5 feet tall.
What’s the chicken mimic dinosaur?
That’s another nickname for Anzu and other similar species with bird-like features.
Are chickens velociraptors?
They are distant cousins! Chickens and velociraptors share a dinosaur ancestor.
Is dinosaur DNA still alive?
Not exactly. But parts of dinosaur DNA survive in birds like chickens.
Conclusion: From Dinosaurs to Chickens – A Wild Ride Through Time
So, there you have it.
The chicken-looking dinosaur is real. It’s Anzu Wyliei, the wild “chicken from hell.” It lived 66 million years ago, had feathers, a beak, and legs made for speed.
Today, its fossils give scientists a better understanding of how birds evolved, and why a chicken might just be your T. rex’s tiny cousin.
