Known locations: China,‭ ‬Liaoning Province‭ ‬-‭ ‬Sunjiawan Foramtion.

Fossil representation: Holotype based upon a jaw and teeth,‭ ‬remains of further remains including a skull and several postcranial elements have now been added to the genus.

       Crichtonsaurus seems to have been a fairly small genus of ankylosaur that lived in China during the earlier stages of the Late Cretaceous period.‭ ‬As an ankylosaur Crichtonsaurus would have been a squat quadrupedal dinosaur that browsed upon low growing plants.
       At the time of writing two species of Crichtonsaurus have been identified by Chinese palaeontologists,‭ ‬though some research has already cast some doubts upon the apparent validity of these species.‭ ‬In a Ph.‭ ‬D thesis written by Victoria Megan Arbour,‭ ‬it was noted that there was no clear link between the holotype specimen of Crichtonsaurus and the later referred fossils,‭ ‬and that on this basis the type species C.‭ ‬bohlini was dubious.‭ ‬Arbour also stated that at least one partial skeleton attributed to C.‭ ‬bohlini should be moved to the second species C.‭ ‬benxiensis.‭ ‬However it was noted that there are clear differences in the scapulas‭ (‬shoulder blades‭) ‬of the known fossil specimens,‭ ‬and that itself does support the presence of at least two ankylosaurs species/genera in the Sunjiawan Foramtion.
       Crichtonsaurus was named after the famous writer Michael Crichton.‭ ‬Among other things,‭ ‬Michael Crichton wrote many great‭ ‬bestselling books,‭ ‬two of which‭ ‬will be known to many dinosaur fans being Jurassic Park in‭ ‬1990,‭ ‬and The Lost World in‭ ‬1995,‭ ‬both of which were remade into,‭ ‬major blockbuster movies in‭ ‬1993‭ ‬and‭ ‬1997‭ ‬respectively,‭ ‬which would‭ ‬also in turn spawn their own sequels.
