"though I don't agree with Tyrannosaurus rex, at least he tries to contribute."
-Edaphosaurus replying to Rexby
Tyrannosaurus rex arrived in mid-September of 2012, but began posting frequently only in early January 2013. He wasn't as mature as Paleoworld-101, PredatorX, or Pinky And Ze Brain. He was insulted by T-RexUSA, and especially rexby. This frustrated him. Though PredatorX came to his side. Tyrannosaurus rex did not leave the forum and ignored these trolls. He was then regarded as a contributur by most other contributors. His rate of posts began to decline as the summer of 2013 came, until he stopped posting.
