• 144 to 65 Million Years Ago
• The Jurassic Period

The Triassic Period

• The Triassic period was named in 1834 by the
  German geologist Friedrich August Von Alberti
• This is the first stage of the Mesozoic era which
  is referred to as the age of the dinosaurs.
• This period took place 248-208 million years ago.
• Pterosaurs or flying reptiles made their first
  appearance here as well as frogs, turtles, and
  crocodiles.
• During the Late Triassic period, many small
  mammals also arose.
