This was the Jurassic Period, 199.6 to 145.5 million years ago* — a 54-million-year chunk of the Mesozoic Era.

How many years did the Triassic period last?

The Triassic (/traɪˈæs.ɪk/ try-ASS-ik) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago (Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era.

What was the world like during the Jurassic period?

The Jurassic Period, part of the Mesozoic Era, was a very different world than what exists today.
