Rock scratches hint at future quakes

The 23-million-year-old bones of the newly-discovered giant, Simbakubwa kutokaafrika, had been left for nearly 40 years in a drawer

Hidden mysteries lie in wait inside Kenya’s fossil treasury

A diagrammatic representation of the Earth in the Archaean showing subducted ocean floor carrying its chemical signature into the deep mantle. The signature which includes water and chlorine is preserved in melt inclusions contained within olivine and carried back up to surface within komatiite lava flows.

This fossilized tree leaf, is the first of their kind to have been found in the area. Alexandre Demers-Potvin, used the samples he collected to establish that Eastern Canada would have had a warm temperate and fully humid climate during the middle of Cretaceous period.
