Archeopteryx lithographica is an emblematic species of evolution, considered a crucial link between dinosaurs and modern birds. It lived during the late Jurassic period, approximately 150 million years ago, and its fossils have been found in the Solnhofen region of Bavaria, Germany. This discovery, first made in 1861, revolutionized our understanding of bird evolution.
Archeopteryx had a size comparable to that of a modern pigeon, with a length of approximately 50 - 70 centimeters and an estimated weight of 0.5 to 1 kilogram. Its anatomy presents a fascinating mix of both avian and dinosaurian characteristics. It had well-developed feathers, similar to those of modern birds, suggesting that it may have been capable of flight or at least gliding. Feathers were present not only on its wings and tail, but also on the body, indicating a possible thermal insulation function in addition to flight ability.
Anatomically, Archeopteryx had jaws with sharp teeth instead of a beak, claws on its wings, and a long, stiff bony tail, more like that of dinosaurs than modern birds. Its skeleton, light but robust, showed adaptations for both arboreal life and flight. The wings had three fingers with claws, which allowed it to climb and hold on to branches.
The habitat of Archeopteryx in the Solnhofen lakes was an environment of shallow lagoons and salt marshes with rich biodiversity. This ecosystem offered abundant food resources, from small reptiles and amphibians to insects, which were part of the Archeopteryx diet.
The discovery of Archeopteryx lithographica has been fundamental in paleontology because it provides direct evidence of the evolutionary transition between theropod dinosaurs and birds. Similarities between Archeopteryx and small theropod dinosaurs suggest that birds evolved from these carnivorous dinosaurs. This iconic fossil has also fueled debates about the evolution of flight and feathers in dinosaurs.
