The Natural History Museum Display consists of a DINOSAUR, a DIORAMA, and a T-Rex. The DINOSAUR is a prehistoric creature that lived millions of years ago and is now extinct. A DIORAMA is a three-dimensional model of a scene, often used to recreate a historical event or natural environment. The T-Rex is a species of DINOSAUR that lived during the late Cretaceous period and was one of the largest land predators of its time. All three elements of the display are meant to give visitors an insight into the history of the natural world.
