Laurasia-Gondwana Video (MV)

Zero parallel location during the Cambrian
Drifts assemble and break her up
Silurian volcanism reforming Laurasia
They are coiled close together

Lapetus rafts terranes to be added back
Neo-Tethys pushes them across the Equator
Microcontinents and blocks amalgamate
Unknown if they originated on her shores

Lycopods invade and dominate the tropics
Terrestrial pteridophytes colonize rapidly
Baragwanathia flora occurs in two strata
Replaced by Archaeopteris and giant moss

Rheic closure, ocean currents reroute
Gondwana rotates clockwise, Australia shifts
South to more temperate coordinates
Coal-forming forests form from ice melting

Now petrified voltziaelan conifers evolve
Extinct glossopterids reach peak diversity
Plant-vertebrate-insect ecosystem results
Hexapods codevelop, therapsids arrive
