Compsognathus longipes is a small theropod dinosaur that lived during the Late Jurassic period, approximately 150 million years ago. Its name, meaning "elegant jaw", reflects one of its most distinctive features. This dinosaur is known for being one of the smallest theropods and for its almost complete skeleton that has provided valuable information about its biology and behavior.
Compsognathus was about 1 meter long and weighed approximately 3 kilograms, making it comparable in size to a modern turkey. Its body was slender and light, with a long, stiff tail that provided balance while running. The hind legs were long and thin, adapted for speed, suggesting that it was an agile runner, probably capable of catching fast prey. Its front legs were shorter but strong, with hands provided with three fingers with sharp claws, useful for capturing and manipulating prey.
The skull of Compsognathus was small and elongated, with large eye sockets suggesting good vision, an essential sense for an active predator. The teeth, sharp and curved backwards, indicate that it was carnivorous. Fossil remains have revealed that it fed mainly on small reptiles and other animals, such as lizards, some of which have been found in the stomach contents of fossil specimens.
As for its skin and feathers, although they have not been found directly on Compsognathus, it is likely that, like other theropod dinosaurs of its size and time, it had some kind of feather-like covering, which could have provided thermal insulation and, possibly, an advantage in terms of camouflage or visual display.
Compsognathus fossils have been found mainly in Europe, specifically in Germany and France, in marine sediments that suggest that it lived in a coastal or island environment. This environment could have offered abundant food resources and shelters, contributing to its survival and evolutionary success.
