Stegosaurus was a stegosaurian dinosaur from the Jurassic. It is characterised for its distinctive spinal plates and thagomizer.
Physical appearance and biology[]
Stegosaurus was a large dinosaur. It had a small head with relatively small eyes. It had a blunt beak for a mouth.
The hind limbs of Stegosaurus were thick and were far larger than its front limbs.
Down the vertebrae of Stegosaurus were spinal plates (or osteoderms) which ran down its neck until near the end of its tail. Each plate had a root-like pattern.
Near the tip of its tail were two pairs of sharp thagomizers. The spikes were slightly curved in shape. This made Stegosaurus different from its relative Kentrosaurus, who had paired spikes throughout the entire length of its tail and on its back.
Stegosaurus was primarily green and yellow with dark green splodges. The spots were outlined with white. The plates were translucent and the rim of the plates was blueish-green.
Behaviour and traits[]
Stegosaurus, in comparison to the other animals in its environment, was a very odd dinosaur. Its body features and shape were very strange compared to the other Jurassic fauna.
Stegosaurus possessed a long row of spinal plates, which are also called osteoderms, lined down its vertebrae. Within the plates were veins that blood could pump through. The blood flushing into the plates would create vivid patterns and colours. This extraordinary display would used for display and intimidation
Near the end of its tail was a pair of sharp spikes. This weapon was called a thagomizer. Stegosaurus used its thagomizer to protect itself from predators like Allosaurus. The force of the impact as well as the sharpness of the spikes would deal a devastating blow - breaking bones and impaling the victim.
Stegosaurus was not the brightest of beings. Its skull was small compared to its body and as a result, its brain was tiny as well. Due to its low intelligence, it was unable to probably determine what was dangerous and what was harmless. Stegosaurus would often mistake small dinosaurs as a threat and those unfortunate animals would often be slaughtered. Stegosaurus had nerve ganglia in its hips region. While it wasn't a true 'second brain' as it was initially suggested, it did help the dinosaur to coordinate its movements, especially in its hind legs and tail, for its brain didn't quite manage it.
For Stegosaurus, reproduction was a very complicated procedure, due to its many ornaments.
