Compsognathus was a small carnivorous theropod dinosaur, from the end of the Jurassic period, million years ago. It was about a metre long, and ran on two legs, using its long tail to keep its balance. The German specimen was found in the Solnhofen limestone in Bavaria, over years ago. Although originally described as a separate species called Compsognathus corallestris, others have since renamed it as another example of Compsognathus longipes. It is one of the few dinosaurs whose diet is known with certainty: the remains of small, agile lizards are preserved in the bellies of both specimens. Thomas Henry Huxley “Darwin’s bulldog”, who was a comparative anatomist, made a study of it nearly years ago. He compared the first fossil bird, Archaeopteryx, with Compsognathus. These two fossils were found in the same rocks : Solnhofen limestone in Bavaria, Germany. The strata come from the end of the Jurassic, about million years ago. Huxley showed that the two were almost identical, except for the front limbs and feathers of Archaeopteryx.
Compsognathus lightweight, muscular body enabled Compsognathus to run fast Compys off of a diet, that don’t get away in.

More Info: en. Due to their high adaptability on the previous islands they were once on, being Isla Nublar and Isla Sorna, the Compsognathus have very little problems surviving in the states. But to prevent inbreeding some compies leave the pack and make a new pack. Acta Geologica Sinica. Jun 23, PM. The largest Compsognathus specimen is estimated to have weighed somewhere between 0. Altispinax Monolophosaurus?
Members of its single species Compsognathus longipes could grow to around the size of a turkey. Paleontologists have found two well-preserved fossils, one in Germany in the s and the second in France more than a century later. Today, C. Many presentations still describe Compsognathus as “chicken-sized” dinosaurs because of the size of the German specimen, which is now believed to be a juvenile. Compsognathus longipes is one of the few dinosaur species whose diet is known with certainty: the remains of small, agile lizards are preserved in the bellies of both specimens. Teeth discovered in Portugal may be further fossil remains of the genus. Although not recognized as such at the time of its discovery, Compsognathus is the first theropod dinosaur known from a reasonably complete fossil skeleton. Until the s, it was the smallest-known non- avialan dinosaur, with the preceding centuries incorrectly labelling them as the closest relative of Archaeopteryx. However, dinosaurs discovered later, such as Caenagnathasia, Microraptor and Parvicursor, were even smaller. The largest Compsognathus specimen is estimated to have weighed somewhere between 0.
