[B]英文版：The generic name is dedicated to Mr. Michael Crichton, author of the book "Jurassic Park". Dinosaurs became one of the most popular scientific subject due to this book. The specific name is dedicated to Dr. B. Bohlin, a well-known Swedish collector of vertebrate fossil including several ankylosaurs along the Silk Road, Northwestern China.
The specimens came from the Sunjiawan Formation of Beipiao Basin, Liaoning Province, northeastern China. The newly found ankylosaur fossil supports the Late Cretaceous age of this unit (Cenomanian-Turonian). The materials contain a fragment of left mandible bearing three teeth (IVPP V 12745); two cervical vertebrae, a complete dorsal (IVPP V12746); four sacral and caudal vertbrae, complete scapula, coracoid, humerus, and femur, as well as various plates and scutes of dermal armor (LPM 101). LPM is the abbreviation of the Paleontology Museum of Liaoning.
Crichtonsaurus is a medium-sized ankylosaur, 3 meters in length on the basis length of vertebrae. The mandible is thin and without outer surface ornamentation. The teeth are small, and typically ankylosaurid in shape. The crown of each tooth is symmetrical with 4 or 5 marginal denticles. The cingulum is strong on the base of crown. Small ridges are found on flatter side of the crown. The centra of cervical vertebrae are short and amphicoelous. The cnetra of dorsal vertebrae are amphiplatyan, with upward-pointing diapophyses. The centra of anterior caudal vertebrae are broad and comparatively short with long transverse precesses. the scapula and coracoid are not fused together as a scapulocoracoid. Dermal plates,scutes, and spikes vary in size and form.
