It's time for a lesson in Jurassic swag, courtesy of UFC fighter Derrick "The Black Beast" Lewis ... who dropped $125k on the a golden T-Rex motor thingy ... and TMZ Sports has the pics.
Lewis hit up Joseph McCamish of Etune Autosports in Houston and told the man he wanted "the baddest T-Rex he could build" ... and was willing to pay big bucks for it.
We talked to McCamish who tells us his guys were up to the task and created a one-of-a-kind ride for the Octagon god.
