(Chinese Academy of Sciences Headquarters) A joint team of researchers from China and Britain revealed a new fossil fauna, the Anji Biota, which document post-extinction sponge-dominated communities from uppermost Ordovician rocks of South China. More than 75 sponge species represent multiple lineages that survived the Late Ordovician mass extinction. Sponges also flourished after other mass extinctions and may have facilitated ecosystem recovery by stabilizing sediment.
