Tyrannosauruses (mostly and also called Tyrannosaurus Rexes or T. Rexes) are a species of carnivorous dinosaurs which existed during the Stone Age featured in the franchise of The Flintstones.
Tyrannosauruses were bipedal carnivorous dinosaurs with massive skulls balanced by their long, heavy tails and their forelimbs were small, though unusually powerful for their size, and bore primary digits.
They rarely saw much use compared to most other dinosaurs and were not as commonly seen, but according to The Flintstones' Wacky Inventions, I Yabba-Dabba Do! and Hollyrock-a-Bye Baby (set 20 years after the original series) tyrannosauruses enjoyed more frequent use, especially in construction, including the Tyrannosaura-Crane. They were also edible with their meat, including the Tyrano-Ribs in the episode, "Dawn of the Disposals", featured in Yabba-Dabba Dinosaurs.
