5. FEATURED PAPER: Modelling Gondwana break-up

   Gondwana break-up changed the global continental configuration, leading to the opening of major oceanic gateways, shifts in the climate system and significant impacts on the biosphere, hydrosphere and cryosphere. Although […]

6. Antarctic fossils show creatures wiped out by asteroid

   A study of more than 6,000 marine fossils from the Antarctic shows that the mass extinction event that killed the dinosaurs was sudden and just as deadly to life in the polar regions.
