Stegosaurus existed from about 155 to 150 million years ago. That was during the Kimmeridgian and Tithonian stages of the Jurassic period.
Like all dinosaurs, Stegosaurus lived in the Mesozoic era. It lived 150 million years ago. That was during the Jurassic period, the second period of the Mesozoic.

The Stegosaurus dates from about 155 - 145 million years ago in the Kimmeridgian and Tithonian age of the Upper Jurassic Period. This was in the Mesozoic Era which was part of the Phanerozoic Eon.Some estimates suggest that it may have survived until the Berrisian (145-140 Ma) in the early Cretaceous Period although this is not generally recognised by most scientist.The geological time units are as followsPhanerozoic Eon (545 Ma - Now)Mesozoic Era (251 - 65 Ma)Jurassic Period(199 - 145 Ma) Cretaceaous(145 - 65Ma)Kimmerridgian age(155 - 150 Ma) & Tithonian age(150 - 145) & Berrisian(145 - 140 Ma)

The Stegosaurus is perhaps one of the most widely recognized dinosaurs due to its armored plates that ran along its back in two columns. The Stegosaurus lived 150 to 145 million years ago during the late Jurassic period.
Othniel Charles Marsh discovered Stegosaurus near the town of Morrison, Colorado in 1877. Since then, Stegosaurus fossils have been found in the Morrison Formation in Wyoming, Colorado, and Utah. In 2006, it was announced that Stegosaurus had also been discovered in Portugal.
Albertosaurus lived between 71 and 68 million years ago. Stegosaurus lived between 155 and 150 million years ago, meaning that they died out 79 million years before Albertosaurus existed. If they had lived at the same time and in the same place, though, Albertosaurus would have hunted Stegosaurus.
It lived on Earth
Stegosaurus never lived with tyrannosaurus Rex due to their different periods of existence.
Baby Stegosaurus would have made an easy meal for almost any carnivorous dinosaur, even small ones like Ornitholestes. However, Stegosaurus lived in herds and the parents would have done their best to protect the youngsters. Adult Stegosaurus had predators too, though. Carnivorous dinosaurs large enough to hunt adult Stegosaurus include Ceratosaurus, Torvosaurus, Allosaurus, Epanterias, and Saurophaganax.
# Stegosaurus laid hard shelled eggs, probably in a nest of vegetation to incubate the eggs. # The hatchlings were raised by their mothers for a while. # After a few years, the young Stegosaurus reach maturity. Soon they lay eggs and a new generation begins.
