Stegosaurus was a Late Jurassic (155-150 Mya) herbivorous quadrupedal dinosaur known for its array of upright plates on its back and strong spiked tail. Heavily built with short limbs, a small head, and large body, Stegosaurus was a defensive dinosaur that likely foraged for twigs and low hanging fruits. Stegosaurus has a body length of 30’ | 9.1 m and a height of 14’ | 4.3 m.
Tyrannosaurus Rex (T-Rex) was one of the largest predatory dinosaurs that ever existed. Living during the Cretaceous period (68-66 Mya) in the forested river valleys of today’s western North America, Tyrannosaurus is a carnivore popularly known for its large 5’ | 1.5 m skull, ferocious serrated teeth, small useless arms, strong tail, and powerful bipedal legs. Tyrannosaurus Rex was 40’ | 12.3 m in length, with a head height of 17’ | 5.2 m and hip height of 12’-13’ | 3.7-4 m.
Height (Hips): 12’-13’ | 3.7-4 m
Period: Cretaceous (68-66 million years ago)
Scientific Name: Tyrannosaurus

Brachiosaurus was an extremely tall dinosaur that lived during the Late Jurassic period (154-153 Mya). Built for browsing for foliage high above the ground surface, Brachiosaurus is characterized by its long neck and body, small head, and larger forelimbs than hindlimbs. Brachiosaurus has a height of 31’-43’ | 9.4-13 m and a body length of 59’-69’ | 18-21 m.
Period: Late Jurassic (154-153 million years ago)
Scientific Name: Brachiosaurus

Spinosaurus was a large carnivorous Cretaceous period (112-93.5 Mya) dinosaur characterized by its large thin back spikes. A giant predator on both land and water, similar to the present day crocodile, fossils prove that the Spinosaurus was as larger or larger than the Tyrannosaurus Rex. Spinosaurus has a length of 49’-51’ | 15-15.6 m, a head height of 16.5’ | 5 m, and an overall spine height of 21.5’ | 6.5 m.
Height (Head): 16.5’ | 5 m
Period: Cretaceous (112-93.5 million years ago)
