# What the Earth was like
Timelapse made using [**11 paleogeography maps**](http://www.stromboidea.de/?n=People.RonBlakey) from Prof. Ron Blakey (NAU Geology).
> *Paleogeographic maps portray immense amounts of data in a single view. When used in time sequence, they show trend and pattern through geologic time.*
Here, the timelapse depicts Earth geological evolution from the Early Jurassic until current epoch:
* Early Jurassic (-200 Ma)
* Middle Jurassic (-170 Ma)
* Late Jurassic (-150 Ma)
* Early Cretaceous (-120 Ma)
[[See the Sketchfab model](https://sketchfab.com/models/6678aed9091248158061c847ee409c10)]
* Middle Cretaceous (-105 Ma)
* Upper Cretaceous (-90 Ma, Turonian)
* Cretaceous - Tertiary boundary (-65 Ma, Maastrichtian/Danian)
* Eocene (-50 Ma)
* Oligocene (-35 Ma)
* Miocene (-20 Ma)
* Holocene (Present)
