Most of us know that the map of earth today is not how earth looked many million years ago. For example, it is well known that the Himalayas are a young mountain range that grew and is still growing as India pushed against Asian continent.

The subject of paleogeography deals with geography at the planet scale. I found this animation that shows earth starting 200 millions year ago and projects the shape 200 million years hence.

While this is amazing, wouldn’t it be great if we could also visualise the life on earth at those points in time? I made a timeline (50 ma gap) of the dominant (or interesting) life-forms of that period. (All images are from Wikipedia)
