Stegosaurus Mandala Coloring Pages

The stegosaurus had seventeen bony plates along its spine, but scientists still debate their exact purpose. They may have been used for temperature control, defense, or displaying dominance to other stegosaurus. The plates were covered in skin and blood vessels, suggesting they were incredibly sensitive.

A stegosaurus measured about 30 feet long from nose to tail and weighed around 9,000 pounds, roughly the size of a school bus. Despite this impressive size, it had a surprisingly small brain, about the size of a walnut, and walked on four sturdy legs.

Stegosaurus were herbivores that munched on low-growing plants, ferns, and shrubs. They had a small head and weak teeth for grinding, suggesting they ate softer vegetation. Their long neck and front legs were shorter than back legs, making them browse at ground level.

The stegosaurus had four sharp spikes on its tail, collectively called a thagomizer. These spikes were powerful defensive weapons used to protect against predators like the allosaurus. Recent fossil evidence suggests tail spikes inflicted serious injuries on attacking theropods.

Stegosaurus roamed Earth during the Late Jurassic Period, approximately 155 to 150 million years ago. They lived alongside famous sauropods like brachiosaurus and diplodocus, long before the more well-known T-rex appeared during the Cretaceous Period.

Stegosaurus disappeared at the end of the Jurassic Period around 150 million years ago. Scientists believe climate change, shifting vegetation, and competition from other herbivorous dinosaurs contributed to their extinction. Their decline happened millions of years before the asteroid impact that killed T-rex.
