Theasaurus 

Theasaurus was not a true dinosaur. It lived long after most dinosaurs and fed on the spare time of the verbose. But mostly, it had trouble spelling and pronouncing the word "thesaurus".

A Theasaurus can still help you find a synonym for "dapper" if you ask it nicely.

Tokisaurus

A scientific failure, named after Toki Wartooth, that experimental scientists had been working on at Dethklok HQ. The Tokisaurus was meant to be a Tyrannasaurus Rex for a Dethklok concert, but during the manufacturing stage, a stran of Toki Wartooth's hair fell into the DNA. The Tokisaurus was immediatley killed after several pictures were taken of it. The autopsy contained scientific information that has been withheld from the public by Dethklok. It's remains are buried at Dethklok Cemetery.

I bought a Tokisaurus collectible at that Dethklok concert
