Facts About Archaeopteryx
You probably haven’t heard of the Archaeopteryx before, but it’s actually a major part of history. In fact, it’s often referred to as the first bird!
The Archaeopteryx lived in the late Jurassic period 150 million years ago and was kind of like a mix of dinosaurs and birds. Keep reading to learn more about the unique Archaeopteryx and check out all the cool facts we have! You’ll be a pro on the bird dinosaur in no time.

What did Archaeopteryx look like?
Given its title as the first bird, it’s no surprise that the Archaeopteryx probably looked like a bird at first sight. If you looked closer, past its feathery wings, you’d notice its long tail and sharp teeth—telltale signs of a dinosaur! Still, it would be a pretty confusing sight given the Archaeopteryx was covered in feathers, especially since the Archaeopteryx was one of the earliest creatures to have them. Check out an example below!
Despite its bird-like appearance, the Archaeopteryx still had lots of dino features. Did you notice the claws on its wings? The Archaeopteryx had sharp claws on its fingers, allowing it to grab food. It also had sharp teeth and a long bony tail, possibly to help it easily swoop down and chomp its food. That said, scientists aren’t sure if it could flap its wings like a modern bird. It’s possible that the Archaeopteryx used its large wingspan to simply glide from tree to tree!

How big was the Archaeopteryx?
The Archaeopteryx was much smaller than most other dinosaurs, standing at only 50 centimetres long and weighing 2 pounds. That’s about the same size as a modern chicken or a raven, so the Archaeopteryx was pretty small! It might not sound impressive compared to giant beasts like the Brachiosaurus, but its lightweight body was exceptionally helpful for a flying creature. As it didn’t have much weight to carry, the Archaeopteryx could easily move at high speeds and possibly flap into the air. Its wingspan was around 60 centimetres, which isn’t huge, but compared to its tiny body, they were massive!

What did the Archaeopteryx eat?
The Archaeopteryx was a carnivore, meaning it hunted and ate meat! Its sharp teeth and claws suggest that it might have hunted small lizards and insects, grabbing them with its claws and using its teeth to chew them up. Some scientists think it stalked prey on the ground and leapt up into the air to snatch food, which might have included small dinosaurs! Others believe the Archaeopteryx hunted like modern birds, swooping down to grab small animals with its feet.
Where did the Archaeopteryx live?
The Archaeopteryx lived during the late Jurassic period in what we now call Germany! Back then, the Earth was warm and humid, making Germany a tropical paradise filled with forests, lakes, and other vegetation. This habitat would have been perfect for the Archaeopteryx to glide between trees and would have been abundant with smaller creatures for it to hunt.
Europe at this time was also covered with shallow ocean, so the Archaeopteryx may also have been able to hunt fish and other small sea creatures. Archaeopteryx fossils have actually been found in what used to be a lagoon, which is kind of like a shallow part of the sea that’s separated from the rest. Some scientists think the Archaeopteryx was prone to falling into the water and getting stuck in the mud. However, this mud is what preserved their fossils so well!

What killed the Archaeopteryx?
The Archaeopteryx lived in the Jurassic period, which was long before the mass extinction event that wiped out the dinosaurs. While scientists aren’t sure what exactly happened to the Archaeopteryx, it’s likely it died out due to more advanced dinosaurs and flying reptiles like the Pteranodon. Given it was such a small creature, the Archaeopteryx likely didn’t stand much of a chance against other dinosaurs, especially those evolving at the end of this period.
Since we only have a few Archaeopteryx fossils, it might also be possible that it simply wasn’t a common animal, meaning it would be harder for the species to survive predators or climate changes. It also wouldn’t have been well-equipped to fight back, so bigger flying creatures likely made it harder for it to survive in the air as well as on the ground.
Fun Archaeopteryx Facts
- The name Archaeopteryx comes from the Greek words “archaios” and “pteryx”, which means ancient wing! Since it was one of the first known birds, it’s a pretty fitting name.
- Like modern flying birds, the Archaeopteryx’s feathers weren’t symmetrical. Although we don’t know if it could fly or simply glide, atypical feather lengths and shapes indicate that it was at least capable of some flight.
- While the clawed fingers on its wing might have been to grab food, they also might have helped the Archaeopteryx climb trees. If it wasn’t able to take flight, being able to climb would help it get up high to glide to other trees.
- Modern birds don’t have teeth, instead using their beaks to peck at food. Although the Archaeopteryx did have a beak, it also had teeth to catch and chew small insects or animals.
- The Archaeopteryx was discovered in 1861, just two years after Charles Darwin created the theory of evolution! The Archaeopteryx was instrumental in proving that we evolved from other animals since modern birds are so similar and likely came from species like the Archaeopteryx.
- Scientists are still debating exactly how fast the Archaeopteryx was, but some suggest it would run at 10-15 miles per hour on the ground, making it as quick as a squirrel!
Closing Summary:
The Archaeopteryx might not have been the biggest or strongest dinosaur around, but it was certainly interesting! It was pretty quick for its size and while it isn’t around today, it helped scientists understand how birds evolved from creatures like the Archaeopteryx. Plus, with its feathers, sharp teeth, and clawed wings, it was still quite a unique dinosaur!
