Archaeopteryx (151-149 mya)

Archaeopteryx is one of the most famous animals of the Jurassic Period and perhaps the best-known “transitional fossil” in the history of science. This ancient feathered reptile lived about 150–145 million years ago in what is now Germany and is considered a distant relative of modern birds. Archaeopteryx was the first known animal capable of flight using feathered wings.

When its remains were discovered during the time of Charles Darwin, the find was hailed as a “missing link” between reptiles and birds. At the time, Archaeopteryx truly seemed unique, combining features of both dinosaurs and birds. However, later discoveries in China showed that feathers were widespread among many theropods, meaning Archaeopteryx was not an exception but rather one of many feathered dinosaurs. Even so, its anatomy clearly displays avian traits, making it a crucial form in the evolution of birds.

Archaeopteryx was relatively small — about 60 cm long and weighing up to 1 kg. Its brain was about three times larger than that of modern reptiles and approached the size of a bird’s brain, although its structure remained more primitive.

Its wings bore asymmetrical flight feathers, like those of modern flying birds. This shape generates lift and makes powered flight possible. The entire body of Archaeopteryx was covered in contour feathers, giving it the appearance of a true bird.

At the same time, Archaeopteryx retained many distinctly dinosaurian features: each wing had three fingers, two of them ending in sharp claws; its jaws contained small teeth, and there was no beak. Its pelvis was intermediate between that of birds and non-avian dinosaurs, and its tail was long, consisting of 21–23 separate vertebrae, unlike the short fused tail of modern birds.

Scientists suggest that Archaeopteryx lived in warm, lightly wooded environments with scattered trees and shrubs, hunting small animals and insects. It likely spent much of its time on the ground or in the trees, using flight mainly to escape predators or move between habitats.
