Cretaceous Period 143 - 65 Million Years ago

The Cretaceous period takes its name from the Latin creta for chalk, which was deposited towards the latter half of the period. It is the last period of the Mesozoic era where we know that the first seed bearing plants developed and the dinosaurs reached their peak before they became extinct towards the end of the Cretaceous.

During the early Cretaceous the climate was sub tropical with wet and dry seasons but by the end of the Cretaceous the world began to look much more like we know it today.

Jurassic Period 208 – 146 Million Years Ago

The Jurassic period was the middle period of the Mesozoic era. The name Jurassic comes from the Jura Mountains between France and Switzerland where the rocks formed during this period were first studied.
