Up to 13 meters in length and 9 metric tonnes in weight, tyrannosaurs had the largest teeth of any carnivorous dinosaur, capable of tearing flesh and crunching bone. They also had highly-developed senses of smell, on par with vultures, and incredibly acute eyesight—better than eagles. They were the apex predators of the late Cretaceous period, roaming over what is now western North America, in environments ranging from bayous to semi-arid plains. Their giant rear legs and swaying tail made them efficient walkers, capable of stalking prey over long distances before closing in for the kill with a burst of speed. They could also smell carrion at a great distance then chase other predators from the carcass, making them the bullies of the Cretaceous lunch room.
This amazing walking dinosaur model is a wind-up DIY wooden scale model of a full-grown Tyrannosaurus Rex. The top of the tail conceals the winding key. Remove the key and insert into the ratchet mechanism on the dinosaur's left side, making sure the head of the left femur is clear of the opening (if you need to, flip the on/off switch to the "on" position, then spin the gear above the T-Rex's shoulders to move the leg). Flip the on/off switch to the "off" position (toward the head) and wind the mechanism half a dozen times clockwise, replacing the key to its position between the tail and body. Place the Tyrannosaurus on a smooth, flat surface, holding the automaton by the body (don't squeeze the legs together!), flip the on switch and release. Your Tyrannosaur will stalk away, in search of its next meal, its tail swinging and jaws crunching up and down in anticipation. It's actually kind of terrifying!
The Ugears Tyrannosaurus Rex is rated "Advanced" level, has 249 parts, and promises 8 hours of exciting assembly time. No glue or special tools are required for assembly. Just follow the step-by-step instructions in 11 languages (English, German, Ukrainian, French, Polish, Spanish, Portuguese, Japanese, Italian, Chinese and Korean) to guide your build, making sure to properly sand and lubricate all moving parts for optimal dino function.
