Imagine a flying reptile that looks like it got its head from one group and its tail from another. That is Darwinopterus. It lived in the middle Jurassic period, about 160 million years ago, in what is now China.1 2

Datu dibertigarriak

Darwinopterus was a 'transitional fossil' because it had a head and neck like later short-tailed pterosaurs, but a long tail like earlier ones.1 2

More than 30 fossils of Darwinopterus have been found, all from the same rock layer in China.1

The name Darwinopterus honors Charles Darwin, the famous scientist who came up with the idea of evolution by natural selection.1 2

Darwinopterus had a very long tail, made of more than 20 vertebrae, with thin bony rods wrapping around it.2

Its skull was huge, almost twice as long as the bones of its back. That's even bigger than many later pterosaurs.2

Darwinopterus had about 15 pairs of slender, spike-like teeth in its mouth, good for gripping prey.2

The first Darwinopterus species, D. modularis, was named in 2010. Later, three more species were added in 2011, 2025, and 2010.1 5

Darwinopterus: gehien egindako galderak

?Was Darwinopterus a dinosaur?

No, Darwinopterus was a pterosaur, a flying reptile that lived while dinosaurs walked on land. Pterosaurs are not dinosaurs.4 1

?How big was Darwinopterus?

It was a relatively small pterosaur. Its skull was about 0.14 to 0.19 metres long, and its forelimbs were about 0.34 to 0.46 metres long.2

?What did Darwinopterus eat?

Its slender, spike-like teeth were well suited for gripping prey, so it probably caught small animals like insects or fish. Scientists infer this from the tooth shape.2 1

?Why is Darwinopterus called a transitional fossil?

Because it had a head and neck like later short-tailed pterosaurs, but a long tail like earlier ones. This mix shows how one group evolved into the other.1 4
