A opposite trex, A opposite T. rex is a small, lightweight dinosaur with a short, narrow head and a tiny mouth filled with flat, dull teeth. It has very long, powerful arms with delicate fingers, perfect for fine motor skills. Its body is thin and fragile, supported by slender legs built for slow, careful movement. Instead of a long balancing tail, it has a short, useless nub. Overall, it looks harmless, graceful, and easy to ignore, more like a shy scavenger than a fearsome predator. See more
