Back when dinosaurs first began to roam the Earth, our planet was composed of a single landmass that formed the supercontinent Pangea. Its extreme conditions can offer insights to scientists studying our changing climate today.
in the oceans. Pangea’s flora may not have been to alien to us in some ways, as it was dominated by species such as conifers, ferns and horsetails, Olsen continues. Flowering plants, however, if present, were very rare.
Jessica Whiteside, a professor of geological sciences at San Diego State University, explains that biodiversity was flipped in Pangea compared to today’s world.

Scientists have now exploited those limitations to write a cookbook of hundreds of chemical recipes with the potential to give rise to life. Their ingredient list could focus the search for life elsewhere in the universe by pointing out the most likely conditions -- planetary versions of mixing techniques, oven temperatures and baking times -- for the recipes to come together.
