Geologists Have, For The First Time, Animated How The Earth’s Plates Moved Relative To Each Other Over The Last Billion Years. The Geologists Spent 4 Years To Create The Animation, Using Paleomagnetism And Current Tectonic Plate Data. The Animation May Help Explain How Earth Became Habitable For Complex Creatures.

A Software Engineer, Ian Webster, Inspired By Plate Tectonics, Has Created A Map That Can Enable Anyone To “Time Travel” To The Past, Up to 750 Myrs Ago, To Find The Location Of Modern-Day Landmark Or City, With Associated Location Fossils. This Location Shift Is Because The Continents Have Been Drifting Away And Towards Each Other.

The Recently Discovered Fossilized Tail Of The First River Dinosaur, Spinosaurus Aegyptiacus (SA), In Southern Morocco, Indicates That Dinosaurs Were Not Only Land And Air Animals, But Were Also Powerful Swimmers That Adapted Quite Well In Water. The Study Notes That SA Prowled The Rivers That Flowed Through The Sahara Desert 100 Myrs Ago. Fascinating!

The USGS, In Collaboration With NASA And The Lunar Planetary Institute, Have For The First Time Created A Detailed Map, 1:5,000,000 scale, Of The Entire Moon Surface Rock Types. The Geologic Map Is Expected To Aid Future Moon Missions And Used As A Learning Tool. The Map Was Created From Recent Satellite Missions And Historic Apollo-Era Data. Cool!!
