How Big Did T.rex Get? E.D. Cope: The New Giant

The true size of Tyrannosaurus rex is hotly debated. Tyrannosaurus rex is the megatheropod with the largest sample size, which may lead to finding the biggest specimens. The gigantic Tyrannosaurus rex specimen E.D. Cope, “Copium rex,” may be the biggest Tyrannosaurus rex specimen yet described in the literature. This video takes measurements from paleontologists and uses them to calculate how big was the biggest Tyrannosaurus. E.D. Cope was likely bigger than Scotty, Sue, Trix, and almost any other theropod. With new estimates placing it at approximately 1500 kilograms heavier than even the dentary Giganotosaurus specimen.

A special acknowledgement goes to Ivano Borghi for creating the fantastic 3D models of Cope featured in this video. Check out his ArtStation here: https://www.artstation.com/infestedivy

Thanks also goes to Peter Larson, Scott Hartman, and Asier Larramendi for providing their various perspectives on Cope’s measurements and overall size.
