Crichtonsaurus was a genus in the Ankylosauridae family. They lived in China during the Late Cretaceous Period. Only one species of this genus is known: C. bohlini. Crichtonsaurus was a medium-sized ankylosaur, 3 meters in length on the basis length of vertebrae. The teeth are small, and typically ankylosaurid in shape. Dermal plates, scutes, and spikes vary in size and form. The specimens of the first species were discovered in 2002 in China, and named by paleontoligist Dong Zhiming. A second species was discovered in 2007 in rocks of the early Late Cretaceous-age (Cenomanian-Turonian) Sunjiawan Formation of Beipiao Basin, Liaoning Province, northeastern China. Only a skull and other parts of the skeleton were found. These would later be reclassified as Crichtonpelta.
In 2014, a study determined that Crichtonsaurus was actually a nomen dubium, as it was incomplete and had no traits to distinguish it from other ankylosaur species in the area. The second species, C. benxiensis, was determined to actually be different enough from other ankylosaurs to be removed from Crichtonsaurus and given its own genus, Crichtonpelta.
Scientists at the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences named the new ankylosaur species Crichtonsaurus bohlini in honor of Michael Crichton because "dinosaurs became one of the most popular scientific subjects due to (his) book."
Crichtonsaurus is one of five dinosaurs that are available in deluxe edition of the game. This will be the first time it has ever physically appeared in any Jurassic Park game. Its' coloration is a simple dull brownish-grey.
