Dane's little brother Trek is a bit of a copycat. He is always following Dan around and trying to get him to play dinosaurs with him. Of course, that's just because Trek idolizes Dan. Dan loves his brother but finds it a bit of a challenge to include him in his dinosaur research. Surprisingly, Trek will usually end up helping Dan out. Trek's innocence usually points out the simple truth of a situation.
5 years after Dan stopped his Dino Experiments Dan asked Trek (By a video message) if he could finish them for Dan. Trek now see`s Dinosaur like Dan and solves Dino Experiments like Dan. With the help of His Friends: Penelope, Bobby, and Hannah.
