Compsognathus was once thought to have been the smallest dinosaur. It has now been beaten by dinosaurs such as Microraptor and Parvicursor.


Compsognathus was about the size of a goose, but its sharp teeth and pointed claws would have made it a deadly predator.



"Elegant jaw"


Compsognathus was a small, bird-like dinosaur with a delicate, long skull and a tapered snout. Its skinny body was perfect for life on the run. 



Compsognathus lived during the Late Jurassic.

They Call it Home

In the Late Jurassic, this area of Europe was an archipelago in the Tethys Sea. Compsognathus would have lived alongside Archaeopteryx and Pterodactylus around lagoons situated between beaches and coral reefs. A tropical paradise!

What Big Teeth You Have

Compsognathus had small, sharp teeth for catching small lizards.

The Poop Scoop

Dinosaur Poop

We haven't found any poop, but one fossil Compsognathus was found with a lizard in its guts.


The Most Fantastic Find

Compsognathus was first discovered in 1859 in Bavaria, Germany, by Joseph Oberndorfer. Inside the ribcage of the fossil was a lizard known as Bavariasaurus. The lizard was first thought to be an embryo, but in fact it was this Compsognathus' prehistoric lunch. Direct evidence of predation in the fossil record is extremely rare and this gives us a unique insight into this dinosaur's hunting behaviours.

From The Expert

Compsognathus is found in the same rock units as the oldest known bird, Archaeopteryx. The similarity of their skeletons led early scientists like Thomas Henry Huxley to suggest that birds evolved from dinosaurs.

Dino On The Go!

Compsognathus had hollow bones, a long neck and tail, and strong bird-like hind limbs. It has one of the fastest estimated speeds of any dinosaur.

Family Album

Family Album

Compsognathus is a member of the theropod subgroup Compsognathidae, which includes several species of small, agile predators. Other Compsognathidae included Sinosauropteryx and Juravenator.



Compsognathus Vision

This dinosaur's eye sockets were exceptionally large. It would have needed binocular vision for hunting small, agile lizards and mammals.

The Skinny On Their Skin


Compsognathus might have had feathers.


What's In The Nest?

Compsognathus Egg

Compsognathus would have laid eggs in a nest like other dinosaurs. If they did possess feathers, as palaeontologists suspect, they would have brooded their eggs, just like a bird.



compsognathus brain size

Compsognathus had a small head and, based on its closest relatives, a relatively large brain, making it one of the more intelligent dinosaurs.


Quite The Bite

Compsognathus had a slender jaw - perfect for eating small vertebrates and, possibly, insects.



Good Eatin'

Plant Icon

Compsognathus had solid claws with three digits for grasping its quick prey. It hunted lizards like Bavariasaurus, which it would have ingested whole!


Parental Guidance

Compsognathus Parent and Child

Based on their closest relatives, it is highly likely that Compsognathus brooded its nest of eggs and set apart at least some of its time to bring up its offspring.


True Colours

Color Wheel

Palaeontologists believe that Compsognathus would have had feathers, because its closest relatives had them. If this is true, Compsognathus may have been quite colourful.
