Stegosaurus existed from about 155 to 150 million years ago. That was during the Kimmeridgian and Tithonian stages of the Jurassic period. The Jurassic was the second period of the Mesozoic era.
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)
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.
Stegosaurus was a large herbivore. Like large herbivores today, they probably spent almost their entire day foraging. They also would have drank some water every day and slept at least for a short time. Mother Stegosaurus probably raised their young for a period of time, as evidenced by tracks of an adult Stegosaurus that overlap those of a juvenile.
The Jurassic period - about 200 million to 145 million years ago.
