<dinofyi-dinosaur slug="stegosaurus"></dinofyi-dinosaur>Stegosaurus is famous for its double row of large bony plates along its back and the spiked tail (thagomizer). Despite its large body, its brain was only the size of a walnut. The plates may have been used for thermoregulation and display.
Physical Description
| Measurement | Value | Human Scale |
|---|---|---|
| 全長 | 9.0 m | roughly the length of a large SUV |
| Height | 4.0 m | — |
| 体重 | 5.0 t | about the weight of 0.8 elephants |
Diet & Feeding
Stegosaurus was a plant-eating dinosaur. Herbivores typically fed on ferns, cycads, conifers, and other vegetation available during their era. Many herbivorous dinosaurs developed specialized teeth and digestive systems for processing tough plant material.
Time Period
Stegosaurus lived during the Jurassic Late period of the Mesozoic Era, approximately 161.5 to 145.0 million years ago.
One of the most iconic periods for dinosaurs. Giant sauropods like Brachiosaurus and Diplodocus roamed alongside predators like Allosaurus. Archaeopteryx, the earliest known bird, appeared. The Morrison Formation preserves an extraordinary fossil record from this time.
