Tristansaurus-Rex 

The most dangerous of all dinosaurs for a number of reasons; Firstly it has opposable thumbs, Secondly it has a markedly larger brain than dinosaurs usually exhibit, and most importantly because it is the only one not extinct.

The Tristansaurus-Rex was locked in mortal combat with the imposing Chupacabra.
