Editing Mesozoic (section)

===Microbiota===
At the dawn of the Mesozoic, ocean plankton communities transitioned from ones dominated by green [[Archaeplastida|archaeplastidans]] to ones dominated by endosymbiotic algae with red-algal-derived plastids. This transition is speculated to have been caused by an increasing paucity of many trace metals in the Mesozoic ocean.<ref>{{cite journal |last1=Zhang |first1=Qiong |last2=Bendif |first2=El Mahdi |last3=Zhou |first3=Yu |last4=Nevado |first4=Bruno |last5=Shafiee |first5=Roxana |last6=Rickaby |first6=Rosalind E.
