Tyrannosaurus rex

Tyrannosaurus rex

Also known as T. rex, T-Rex

Tyrannosaurus rex dominated late Cretaceous ecosystems as an apex macropredator equipped with bone-crushing jaws capable of generating over 35,000 newtons of force. Forward-facing eyes provided acute stereoscopic depth perception comparable to modern raptors, while massive olfactory bulbs granted an exceptional sense of smell for tracking herds or locating carcasses across expansive river deltas. Juveniles possessed slender, fleet-footed proportions and likely occupied different ecological niches before undergoing dramatic growth spurts during their teenage years.
