Scientists have unveiled Khankhuuluu, a new Mongolian dinosaur species that predates and closely resembles early Tyrannosaurs. With its long snout, small horns, and lean build, it represents a transitional form between swift mid-sized predators and giant apex hunters like T. rex. The find also suggests that large Tyrannosaurs first evolved in North America following an ancient migration from Asia.
