The Metal Earth models are amazingly detailed etched models that are fun and satisfying to assemble. Each model starts out as 4 inch square metal sheets and you simply pop out the pieces using wire cutters and follow the included directions to assemble your model. The species Tyrannosaurus rex (rex meaning "king" in Latin), commonly abbreviated to T-Rex, is one of the most well-represented of the large theropods. Tyrannosaurus was a bipedal carnivore with a massive skull balanced by a long, heavy tail. Relative to its large and powerful hind limbs, Tyrannosaurus fore limbs were short but unusually powerful for their size and had two clawed digits. It was among the last non-avian dinosaurs to exist before the Cretaceous-Paleogene extinction event. The model measures 6.7 x 0.87 x 2.4 inches when assembled. Difficulty level: Moderate. No glue or solder needed. Choking hazard Imported Material & Care Plastic Spot clean only
