Dr. Cretacia is Rex Owen's mother and Dr. Ancient's wife.

Character DesignEdit

Like her son, Dr. Cretacia has short blonde hair. She wears a pink suit with white cuffs at the end, a blue vest, and glasses.


Like her butler, Jonathan (his Japanese name being "Jurasson"), Dr. Cretacia's name is parody of a time period in the Mesozoic Era, specifically the word "Cretaceous" which is the ending period of the Mesozoic Era and the extinction of the dinosaurs.


Dr. Cretacia has a rather outgoing personality, unlike her husband's more cool and reserved one. She and her husband also really love Rex so much.



  • Rex also inherited her blonde hair.
  • She has an outgoing and silly personality, much like Dr. Owen.
