The "delicate jaw" was discovered in the 1850s in Bavaria, Germany by Dr. Oberndorfer and described by Johann A. Wagner in 1859. Compsognathus lived during the Late Jurassic Period about 156 to 145 million years ago. According to CSC it was 1 and half meter (5 ft) long, .60 meter (2ft) high and 11 pounds (5kg) in weight. Compsognathus can be found on Isla Sorna as well as possibly Isla Nublar. Dr. Robert Burke, the Paleontologist of the InGen Expedition to Isla Sorna in 1997, either mistook Compsognathus to be Procompsognathus triassicus or both genus are present on Sorna.
