What was the land and sea like in the Mesozoic era?

The Mesozoic period (roughly 180MYA) was a period when much change was happening in the Earth's continental arrangement. The final stage of the break up of the supercontinent Pangaea is generally considered to have taken place in this period. Land and sea were different to how we see them today. Pangaea was on the onset of forming 2 smaller supercontinents called Laurasia and Gondwana. The Atlantic Ocean had not yet formed. The Himalayas were not there. It was a very different picture to what we see today. Have a look at this page for further details concerning the break up of Pangaea. http://en.wikipedia.org/wiki/Pangaea
